Low-pressure systems in various regions of the world can spawn supercell thunderstorms when atmospheric conditions are ripe. Supercells are also known to produce extreme winds and flash flooding. If thunderstorms are the menace that every pilot, IFR or VFR, learns to respect at the greatest possible distance, embedded thunderstorms represent the trickiest for an instrument pilot to avoid penetrating. A farmer has 19 sheep All but 7 die How many are left? In that situation, satellite images that displays the cloud top temperature can be used. Embedded thunderstorms (or cumulonimbus): Thunderstorms (or cumulonimbus (CB) clouds) that are embedded in cloud layers or concealed by haze. Questions? Quiz: Can You Answer These 6 Aircraft Fuel Questions? . The horizontal and vertical coordinates of the point on the rope where the $i$ th balloon is attached are $x_i$ and $y_i$, and $T_i$ is the tension in the $i$ th segment. We recognize our responsibility to use data and technology for good. Up to date for and complete with all charts and figures and professional, illustrated explanations. This causes the sound of thunder. Thunderstorm development is associated with a variety of boundaries in the Earth's planetary boundary layer. Select the correct answer that completes each statement or Some supercells produce tornadoes in addition to large hail and wind damage. They may be isolated, grouped together in clusters, or organized in lines. What is the average 40 yard dash time for a 11 year old boy? In Fig. A squall is a sudden increase of at least 15 knots in average wind speed to a sustained speed of C- 20 knots or more for at least 1 minute. Supercells are highly organized storms characterized by updrafts that can attain speeds over 100 mph (160 km/h) and are able to produce giant hail with strong or even violent tornadoes. *A clear area in a line of thunderstorm echoes on a radar scope indicates. They will rarely produce any precipitation. To share with more than one person, separate addresses with a comma. Supercells have a distinct appearance on Doppler radar, which often features a so-called hook echo on the lower-left portion of thestorm. In areas of South America and Africa that are very close to the Equator, there can be more than 180 days with thunder every year. An idealized supercell. This combination of changing wind directions and speeds creates a horizontal rolling motion in the lower atmosphere. Wiki. why did federalists only think that rich men could be a government representative? *Which type cloud is associated with violent turbulence and a tendency toward the production of funnel clouds? Is Flying Through Snow Considered 'Known Icing'? People are safer inside a building or a car and away from open doors, windows, and electrical appliances. In general, the risk of thunderstorms is lower in occluded fronts that appear east and south of the low (for east moving lows on the Northern Hemisphere), and higher in occluded fronts north and west of the low. Thunderstorms are a common weather disturbance. [News sharing] UK CAA Reveals Almost 15,000 Ghost Flights Operated During The Pandemic, [Youtube] Air Crash Investigation crash of Continental 3407, News Sharing: Video shows the shocking moment when a DHL cargo plane split in 2 after making an emergency landing, Pilots Handbook of Aeronautical Knowledge, FAA-H-8083-25B, Aviation Maintenance Technician HandbookAirframe, Volume 2, FAA-H-8083-31A, Understanding Weather & Climate, Books a la Carte Edition (6th Edition) #ISBN-13: 978-0321773227 #ISBN-10: 0321773225. Rising near-surface air in an unstable air mass expands and cools, making it warmer than its environment, which causes it to rise even farther. 15 miles ahead of the associated precipitation. C- Thunderstorms are obscured by other types of clouds. They are typically as wide as they a high. In effect, the falling rain turns the updraft into a downdraft. Precipitation is sparse or well removed from the updraft and/or often is transparent. A convective SIGMET may be issued for any convective situation which the forecaster feels is hazardous to all categories of aircraft. Heavy rain: Could be an indicator of embedded showers and hence a risk of lightning, especially in cold fronts and occluded fronts. Embedded thunderstorms are likely found in warm from occlusion Surface Weather Chart Tornadoes This website uses cookies to help deliver and improve our services and provide you with a much richer experience during your visit. Which weather phenomenon signals the beginning of the mature stage of a thunderstorm? An isolated thunderstorm is a storm that only effects 10 percent thunderstorm, a violent short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail, and strong gusty winds. Thunderstorm types may be classified as: a. Which type cloud is associated with violent turbulence and a tendency toward the production of funnel clouds? Sustained surface winds of greater than 30 knots at the surface. Which politician received the most support from younger voters A. Ross Perot? The speed at which the entire cluster of thunderstorms move downstream can make a huge difference in the amount of rain any one place receives. Lighting has serious potential to temporarily blind pilots. The classic supercell will have a large, flat updraft base with striations or banding seen around the periphery of the updraft. SIGMETs are issued for 6 hour periods for conditions associated with hurricanes and 4 hours for all other events. Quiz: 6 Questions To See How Much You Know About IFR Weather. This rotating updraft is known as a mesocyclone ILS Critical Area: When Should You Hold Short? 01:50 PM Eastern, National Centers for Environmental Prediction, N A T I O N A L W E A T H E R S E R V I C E, National Oceanic and Atmospheric Administration, hail greater than or equal to 3/4 inches in diameter, wind gusts greater than or equal to 50 knots. It can produce winds as fast as 300 miles (483 kilometers) per hour. It will open up a new set of resources for assistance. Read this article if you want to know how to differentiate between dark thunderstorms and dark stratocumulus clouds. *Where do squall lines most often develop? A- Downdrafts are kept cool by cold rain which tends to accelerate the downward velocity. Quiz: Can You Answer These 6 IFR Preflight Planning Questions? In addition, turning maneuvers increase stress on the aircraft, According to NOAA: Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. There is probably thunder, lightning, wind, and rain occurring when a thunderstorm is active. 1533, solve for the following values: $R_\text{T}$, $I_\text{T}$, $V_1$, $V_2$, $V_3$, $I_2$, $I_3$, $P_1$, $P_2$, $P_3$, and $P_\text{T}$. One example of these limitations is that the Nexrad weather . CWAs are issued for: An AIRMET advises of weather potentially hazardous to all aircraft but that does not meet SIGMET criteria. Denmark The automatic altitude and speed controls will increase maneuvers of the aircraft thus increasing structural stress, If using airborne radar, tilt the antenna up and down occasionally. CWAs are advisories issued by the Center Weather Service Units (CWSUs) that are for conditions just below severe criteria. When tornadoes are spawned by supercells, they are nearthe hook echoon radar. Quiz: Can You Answer These 6 Airport Operations Questions? Although different from a boundary, some terrain features are known to be preferred locations for the initiation of thunderstorms. Tornadoes obscured by heavy precipitation are typically known as "rain-wrapped.". For example, in a veering wind situation the winds may be from the south at the surface and from the west at 15,000 feet (4,500 meters). Most thunderstorms are single-cell, or a storm that pulses up, rains for half an hour, and dissipates. Precipitation area is two five miles in diameter, (aircraft identification) EXTREME precipitation two zero miles west of Atlanta V-O-R, two five miles wide, moving east at two zero knots, tops flight level three niner zero, Above all, remember: never regard any thunderstorm "lightly" even when radar observers report the echoes are of light intensity; Avoiding thunderstorms is the best policy. (Note segment 0 is the segment between the point of attachment and the first balloon, and segment $N$ is the segment between the last balloon and the other point of attachment). The smartest way to avoid thunderstorms is to keep your distance, and never fly through embedded thunderstorms. Copyright TWC Product and Technology LLC 2014, 2023. With the lack of precipitation, no "hook" seen on Doppler radar. issued outside of the CONUS follows the international coding standard. There is a potential for severe and extreme clear air turbulence, Don't fly without airborne radar into a cloud mass containing scattered embedded thunderstorms. The storm is rotating counter-clockwise (red arrows), which is typical for most long-lived supercells in the Northern Hemisphere. why granite is more suitable than marble for astatue? Thunderstorms are so called because of the thunderous loud noise . As the lightning heats the air, it causes it to expand. A- during the downdraft and heavy rain showers. It represents extreme convective activity in the atmosphere, with both updrafts and downdrafts reaching high speeds. AIRMETS are also amended as necessary due to changing weather conditions or issuance cancellation of a SIGMET. source: FAA/NOAA Aviation Weather Services (AC 00-45G) Ace Any FAA Written Test! Atmospheric pressure changes due to a thunderstorm will be at the lowest value. Thunderstorms are most common in the late afternoon, but can occur at any time of the day. Weve been busy, working hard to bring you new features and an updated design. Pilots may encounter thunderstorms of different size and types. Long-lived strong squall lines after called "derechos" (Spanish for 'straight'). Snow: Lightning can in some rare cases occur in connection with snow showers but is rather uncommon (at least in northwestern Europe). There is probably thunder, lightning, wind, and rain occurring when a thunderstorm is active. However, if atmospheric conditions are right and the ordinary cell is strong enough, there is the potential for more than one cell to form and can include microburst winds (usually less than 70 mph/112 km/h) and weak tornadoes. This means in the absence of moisture, but presence of thunderstorms, satellite views will not produce a visual return! *What is a difference between an air mass thunderstorm and a steadystate thunderstorm? Shear turbulence from a thunderstorm has been encountered. When the sky is yellow after a thunderstorm, that means the sun is trying to penetrate through the thick clouds.If the sky is yellow during a thunderstorm, that means its a very severe thunderstorm. These storms are the most intense type of thunderstorm. As the name implies, there is only one cell with this type of thunderstorm. If a person is caught outside during a thunderstorm, it is important to stay away from trees because lightning strikes the tallest objects. Supercell thunderstorms are a special kind of single cell thunderstorm that can persist for many hours. JetStream, Comments? Lightning can kill or seriously injure a person, so it is important to follow simple safety instructions during a thunderstorm. On all sides and directly under the thunderstorm cell. Movement: Often rather fast (15-30 knots, sometimes faster). for more about how to use satellite images. Sometimes the atmospheric conditions are such that new cell growth is quite vigorous. It is therefore not uncommon to see lightning during the late night and early morning, and then no lightning detected a few hours after sunset. The smartest way to avoid thunderstorms is to keep your distance, and never fly through embedded thunderstorms. What Happens If You Go Around After The Missed Approach Point On An Instrument Approach? Do's and Don'ts of thunderstorm penetration: Do keep your eyes on your instruments. Embedded or severe thunderstorms expected to occur for more than 30 minutes. The is visible as a lowered, rotating cloud, called a Wall Cloud, forms below the rain-free base and/or below the main storm tower updraft. Swayne is an author of articles, quizzes and lists on Boldmethod every week. When viewed in an open area, classic supercells have the "mothership" appearance often photographed in the Plains states. What feature is normally associated with the cumulus stage of a thunderstorm? $(a)$ Figure 4-43b shows a free-body diagram for the $i$ th balloon. If a tornado were to form, it would usually do so within the wall cloud. More research is underwayto discover why some of these rotating thunderstormsare accompanied by tornadoes while others are not. Please note: Text within images is not translated, some features may not work properly after translation, and the translation may not accurately convey the intended meaning. Scattered thunderstorms not embedded usually can be visually circumnavigated, Don't trust the visual appearance to be a reliable indicator of the turbulence inside a thunderstorm, Don't assume that ATC will offer radar navigation guidance or deviations around thunderstorms, Don't use datalinked weather next generation weather radar (NEXRAD) mosaic imagery as the sole means for negotiating a path through a thunderstorm area (tactical maneuvering), Do remember that the datalinked NEXRAD mosaic imagery shows where the weather was, not where the weather is. Here is the list of hazards: International SIGMETs are defined within a specific FIR. Storms can range in height from 10,000 feet to over 60,000 feet. Thunderstorms are weather phenomena usually accompanied by heavy rainfall as well as strong winds, hail, and tornadoes Thunderstorms: In the winter months, snowfall can occasionally take place in a thunderstorm Such is often termed thunder-snow Alert Examples: Difficulties in forecasting: If there are moderate to heavy showers in a given area, it could be difficult to forecast which of the showers that could develop into thunderstorms. Although the NWS will mention lightning as a hazard in some warning products, lightning Do's and Don'ts if you cannot avoid thunderstorms: Tighten your safety belt, put on your shoulder harness (if installed), if and secure all loose objects, Plan and hold the course to take the aircraft through the storm in a minimum time, To avoid the most critical icing, establish a penetration altitude below the freezing level or above the level of minus 15C, Verify that pitot heat is on and turn on carburetor heat or jet engine anti-ice. Three conditions are necessary for the formation of a thunderstorm: sufficient water vapor, an unstable lapse rate, and an initial upward boost (lifting action). Because of turbulence, it will most likely be difficult to maintain an exact airspeed, so try to stay on the slow side of your Va. Va adds an extra level of protection if you're flying through moderate to severe turbulence in a thunderstorm. *What is indicated by the term "embedded thunderstorms"? Every pilot should know these regulations. Thunderstorms are obscured by other types of clouds. 11:50 AM Mountain| Wind shift: There will often be sudden wind shifts in connection with thunderstorms, both in direction and wind speed. How Mixture Control Works On Carbureted Engines. Thunderstorm formation require three conditions: Unequal warming of the surface of the Earth, Orographic lifting due to topographic obstruction of air flow, Dynamic lifting because of the presence of a frontal zone, Lifting cools air to dew point, condensing water vapor into water droplets or ice crystals, High winds moving up and down and may extend above thunderstorm, Form when the atmosphere is unstable, but there is little or no wind shear, These storms are short lived and last for less than an hour after becoming strong enough to produce lightning, Groups of cells in different stages of development, which have merged into a larger system, The cloud becomes divided into updraft and downdraft regions, separated by a gust front, The gust front may extend for several miles ahead of the storm, bringing with it an increase in wind speed and atmospheric pressure, a decrease in temperature, and a shift in wind direction, Formed as an organized line or lines of multi-cell storms frequently with a gust, They often arise from convective updrafts in or near mountain ranges and linear weather boundaries, usually strong cold fronts or troughs of low pressure, The squall line is propelled by its own outflow, which reinforces continuous development of updrafts along the leading edge, Squall lines tend to be hundreds of miles long, These lines can move swiftly and in some parts of the line, bow echoes can form, bringing with it high winds, dangerous lightning, and possibly tornadoes, Heavy rain, hail, and damaging winds, such as derechos, can occur in a squall line, Large, severe quasi-steady-state storms, which form when the wind speed and direction vary with height ("wind shear") separates downdrafts from updrafts and contain a strong, rotating updraft, These storms normally have such powerful updrafts that the top of the cloud (or anvil) can reach miles into the air and can be 15 miles wide, Most tornadoes occur from this kind of thunderstorms, Turbulence is a large variation in wind velocity over a short distance, While there is some evidence that maximum turbulence exists at the middle level of a thunderstorm, recent studies show little variation of turbulence intensity with altitude, There is no useful correlation between the external visual appearance of thunderstorms and the severity or amount of turbulence or hail within them, The visible thunderstorm cloud is only a portion of a turbulent system whose updrafts and downdrafts often extend far beyond the visible storm cloud, Severe turbulence can be expected up to 20 miles from severe thunderstorms, This distance decreases to about 10 miles in less severe storms, Weather radar, airborne or ground based, will normally reflect the areas of moderate to heavy precipitation (radar does not detect turbulence), The frequency and severity of turbulence generally increases with the radar reflectivity which is closely associated with the areas of highest liquid water content of the storm, NO FLIGHT PATH THROUGH AN AREA OF STRONG OR VERY STRONG RADAR ECHOES SEPARATED BY 20-30 MILES OR LESS MAY BE CONSIDERED FREE OF SEVERE TURBULENCE, Turbulence beneath a thunderstorm should not be minimized, This is especially true when the relative humidity is low in any layer between the surface and 15,000', Then the lower altitudes may be characterized by strong out flowing winds and severe turbulence. So instead, allow airspeed and altitude to fluctuate while maintaining a level attitude. Your pitot tube is covered in ice. A RESTful web service that receives samples and returns a scan result. Thunderstorms can and do cause aircraft structural failure and fatal accidents. Beneath the supercell, the rotation of the storm is often visible as well. Be a persistent feature that lasts for 10 minutes or more, Appear with lots of rising or sinking motion within and around the wall cloud. What is THOR Thunderstorm? The rapidly rising air cools and condenses creating the shelf cloud. The rising air will gradually cool down until reaching saturation and the water content in the air will condensate and form clouds. area will be clear. Thunderstorms are weather phenomena usually accompanied by heavy rainfall as well as strong winds, hail, and tornadoes, In the winter months, snowfall can occasionally take place in a thunderstorm, Differing air masses cause turbulence, worst where updrafts and downdrafts meet, Most severe turbulence in top 1/3rd of storm, A shear zone can be created between the surrounding air and the cooler air of the downdraft, Lightning is associated with thunderstorms, Hail can be significant and thrown miles from a storm. If you encounter a large, deep band of storms and your equipment (or ATC) informs you of the storm's size, you may want to find a quicker exit. Line of thunderstorms at least 60 miles long with thunderstorms affecting 40% of its length. To re-enable the tools or to convert back to English, click "view original" on the Google Translate toolbar. *During the life cycle of a thunderstorm, which stage is characterized predominately by downdrafts? Required fields are marked *. As there will be a net flux of radiation outwards during the nighttime, the temperature in clouds will fall in the top of the clouds. Thunderstorms usually develop between May and September in the Northern Hemisphere. 12:50 PM Central| Sometimes a heavy thunderstorm can create a gust front ahead of the actual thunderstorm with strong gusty winds. Why can multiple alleles provide many different phenotypes for a trait. Thunderstorm clouds hidden inside other clouds or cloud mass. US SIGMETs cover the contiguous United States and follow US coding standards. Britannica does not review the converted text. If you have (and even if you haven't), you've probably heard the recovery acronym "PARE". They are usually violent and short-lived. Sometimes thunderstorms will form in a line which can extend laterally for hundreds of miles. It is therefore important to use satellite images as an additional tool. Although an airmass is unstable, it often needs a lifting mechanism in order for showers and thunderstorms to form. Under your teachers supervision, use a dropper to add iodine solution to a slice of potato, a slice of apple, and a piece of cheese. If an offshore location is far from the coast, there could be problems with both the radar coverage and that heavy showers could be displayed with the same intensity as light or moderate showers closer to the radar location. hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh *What feature is normally associated with the cumulus stage of a thunderstorm? Isolated showers or thunderstorms typically appear in relative cold air after a cold front has passed or forming during the day over land in the summertime and are easy to spot. Quiz: Can You Fly The North Pole RNAV Approach To Runway 18? That hook echo appendage extends southward from the thunderstorm's main core,wherelarge hail and heavy rain are typically located. Read our article for more about how to use satellite images. There are many times where the individual cell moves downstream but addition cells forming on the upwind side of the cluster and move directly over the path of the previous cell. A thunderstorm is a storm with lightning. This helps with thunderstorm flexibility. Bulletins are issued hourly at Hour+55. National Oceanic and Atmospheric Administration. Private Pilot through ATP and mechanic. Area of thunderstorms covering at least 40% of the area concerned and exhibiting a very strong radar reflectivity or a significant satellite or lightning signature. Which term might be used to describe an area of the ribcage? Accessible across all of today's devices: phones, tablets, and desktops. They are responsible for nearly all of the significant tornadoes produced in the U.S. and for most of the hailstones larger than golf ball size. Thunderstorms occur in almost every region of the world. They can and do occur at any time of the year, but are most likely to happen during the afternoon and evening hours and during the spring and summer seasons . Thunderstorms can have a large impact on offshore operations. These "squall lines" can persist for many hours and produce damaging winds and hail. If your autopilot is engaged, consider disengaging altitude or speed hold modes while you're in rough air. (MORE: Where Tornadoes Strike Around the World). b. urethra Because these modes will only increase aircraft maneuvering as the autopilot tries to re-capture its altitude and speed parameters. The same rapidly rising air motions that form the thunderstorm turn this horizontal rotation into a vertical rotation, which can then be spectacularly evident in the circular striations, or layers, visible in the cloud structure of the supercell. A- 1,000 feet for each 10 knots windspeed. You can, and should, declare an emergency with ATC if you get stuck in embedded thunderstorms. active. However, the risk of lightning will be high. The small size of the water droplets indicates that there is a small vertical movement in the cloud. With our huge population, wouldnt this lesses the atmospheric oxygen level over a period of time? The most dangerous feature of a thunderstorm is lightning. are similar to the US SIGMETs except convective SIGMETs are treated the same as other Focus most of your attention on maintaining a level attitude, and allow your airspeed and altitude to fluctuate. Hail can also form embedded with small pieces of debris like tree branches as the debris . Updrafts, and therefore new cells, continually re-form at leading edge of system with rain and hail following behind. ", Don't turn back once you are in the thunderstorm. Supercell thunderstorms are sometimes referred to as low precipitation (LP) or high precipitation (HP). +45 82 30 67 50 an area where precipitation drops are not detected. When supercells develop in a volatile atmospheric environment, they can survivefor dozens or even hundreds of miles over multiple hours. Long story short, this advice by the FAA is broad and doesn't cover every situation. And at night, turn up flight deck lights to the highest setting to help avoid being blinded by lightning. A steady state thunderstorm is associated with B- weather systems. In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground. Embedded thunderstorms referring cumulonimbus or sort of extensive vertical clouds can be obscured by other cloud formations and are not always visible from the ground or while in flight. These cells may be severe and produce hail and microburst winds. Individual thunderstorm updrafts and downdrafts along the line can become quite strong, resulting in episodes of large hail and strong outflow winds which move rapidly ahead of system. An active thunderstorm means that there is currently a thunderstorm in an area indicated. All rights reserved. Thunderstorms are rarely widespread, but it is difficult to determine which showers that will develop into thunderstorms. A classic supercell photographed near Sanford, Kansas, on May 7, 2013. The US does issue international SIGMETs for Alaska and for oceanic areas off lifting forces carry cooler air inward and upward. Most lightning starts inside a thunderstorm and travels through the cloud. With convective activity, there's an increased potential for icing conditions. From the standpoint of electron structure, what do the elements in the $p$ block have in common ? (LO 2.1, 2.2) Any convective SIGMET implies severe or greater turbulence, severe icing, and low-level wind shear. For Windows PCs, Mac, iPhone/iPad, Android, PocketPC, and MP3 Audio.

They form so fast that each new cell develops further and further upstream giving the appearance of the thunderstorm cluster is stationary or is moving backwards, against the upper level wind. Quiz: Can You Identify These 6 Uncommon Airport Lighting Systems? Which weather condition is an example of a nonfrontal instability band? Thunderstorms are a common weather disturbance. mayo 29, 2022 . [RefPilots Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 12-16]. of a given area where it forms. Making city governments better. A common combination supportive of supercells often found in the Plains states is a southerly or southeasterly wind near ground level and a southwesterly or westerly wind higherin the atmosphere. Cumulonimbus clouds: The towering cumulus will often develop further into cumulonimbus clouds and get the typical thunderstorm cloud appearance with an anvil formed cloud. The wind speed in a height of around 10.000ft (around 3.0km), is often a good indicator of both the direction and the speed of isolated showers and thunderstorms. This is due to the great vertical movement within the thunderstorm clouds that will bring down cold air from aloft. Keep in mind, this advice is somewhat subjective. Write a paragraph theorizing what the color change means. Towering cumulus (cumulus congestus clouds): If the atmosphere is unstable enough, the cumulus clouds will develop further into towering cumulus with a height that will exceed the width. In summertime, the rising surface temperature is the most common lifting mechanism. A non-tropical low about 300 miles north of Bermuda is producing storm-force winds. A straight course minimizes the amount of time in the thunderstorms and turning only increases structural stress on the aircraft (FAA). Individual cells can last from less than a half hour to many hours. However, supercells are responsible for spawning the vast majority of all tornadoes violent ones in particular NSSL added. Have you ever practiced a spin? An active thunderstorm means that there is currently a thunderstorm in an area indicated. *Convective clouds which penetrate a stratus layer can produce which threat to instrument flight? The higher the cloud tops are, the whiter they will appear on infrared satellite products, This is due to the colder temperatures at altitude, First and foremost, pilots should circumnavigate, avoid thunderstorms and any area they may be found, Offsetting course by 1 degree will produce 1 NM offset after 60 NM, Over the top (at least 1000' per 10 knots of wind), Penetration should never be considered unless other options are more dangerous, If penetration is the only option, penetrate perpendicular to the storm to fly straight through, Do not attempt to chase every variation of altitude and speed, they are often unreliable, Slow to maneuvering speed or the aircrafts max turbulence speed immediately, to prevent an over-stress, Aircraft loose stability in a turn and it is easier to become disoriented, Fly the attitude indicator and the aircraft will do the rest, Avoid the upper 2/3 of a mature cell (turbulence and hail) and freezing level +/- 2000' (lightning), If utilizing an autopilot, avoid altitude hold settings, but consider heading hold settings to control roll, Turn all cockpit lights to bright to include floodlights, Lower the seat to the bottom to prevent striking head against the canopy and to reduce the blinding effect of lightning, Turbulence, hail, rain, snow, lightning, sustained updrafts and downdrafts, icing conditions-all are present in thunderstorms, The probability of lightning strikes occurring to aircraft is greatest when operating at altitudes where temperatures are between minus 5 Celsius and plus 5 Celsius, METAR reports do not include a descriptor for severe thunderstorms.
