Severe winds occur most often when organized lines of thunderstorms develop in an In small thunderstorms, peak five-minute rainfall rates can exceed 120 mm (4.7 inches) per hour, but most rainfalls are about one-tenth this amount. John Wiley & Sons, Ltd., 2010. Strong thunderstorms reach above 40,000 feet (7.5 mi), which is higher than most passenger aircraft fly. If atmospheric conditions do not support super cellular development, this stage occurs rather quickly, approximately 20–30 minutes into the life of the thunderstorm.
In a typical thunderstorm, approximately 5×10In more contemporary times, thunderstorms have taken on the role of a scientific curiosity. Waterspouts are generally classified as forms of tornadoes, or more specifically, non-Flash flooding is the process where a landscape, most notably an urban environment, is subjected to rapid floods.Downburst winds can produce numerous hazards to landscapes experiencing thunderstorms.
Downburst winds are generally very powerful, and are often mistaken for wind speeds produced by tornadoes,Thunderstorm asthma is the triggering of an asthma attack by environmental conditions directly caused by a local thunderstorm. Large, The downdraft will push down out of the thunderstorm, hit the ground and spread out. It looks like the main concentration of the showers and thunderstorms will be west across central Kansas.
While larger pollen grains are usually filtered by hairs in the nose, the smaller pollen fragments are able to pass through and enter the lungs, triggering the asthma attack.Most thunderstorms come and go fairly uneventfully; however, any thunderstorm can become Preparedness refers to precautions that should be taken before a thunderstorm. Thunderstorms result from the rapid upward movement of warm, moist air, sometimes along a Thunderstorms can form and develop in any geographic location but most frequently within the All thunderstorms, regardless of type, go through three stages: the The first stage of a thunderstorm is the cumulus stage or developing stage. Clouds contain …
Single-cell thunderstorms form in environments of low vertical wind shear and last only 20–30 minutes. For other uses, see Markowski, Paul and Yvette Richardson. In the United States, a thunderstorm is classed as severe if winds reach at least 93 kilometres per hour (58 mph), hail is 25 millimetres (1 in) in diameter or larger, or if Forms of MCS that develop in the tropics are found in use either the A back-building thunderstorm, commonly referred to as a Each year, many people are killed or seriously injured by severe thunderstorms despite the advance warningAcid rain is also a frequent risk produced by lightning.
During this stage, masses of moisture are lifted upwards into the atmosphere. Let's look at how it works.
A thunderstorm is classified as “severe” when it contains one or more of the following: hail one inch or greater, winds gusting in excess of 50 knots (57.5 mph), or a tornado. pp. 209.Schnetzler, Amy Eliza. The average thunderstorm produces about 2,000 metric tons (220,000 short tons) of rain, but large storms can produce 10 times more rainfall.
Well-developed cumulonimbus clouds are characterized by a flat, anvil -like top (anvil dome), caused by wind shear or inversion near the tropopause. John Wiley & Sons, Ltd., 2010. pp. Analysis of Twenty-Five Years of Heavy Rainfall Events in the Texas Hill Country.
There are four main types of thunderstorms: single-cell, multi-cell, squall line (also called multi-cell line) and supercell. The trigger for this lift can be In the mature stage of a thunderstorm, the warmed air continues to rise until it reaches an area of warmer air and can rise no farther.

Often this 'cap' is the In the dissipation stage, the thunderstorm is dominated by the downdraft. In extreme circumstances, the gust front produced by a downburst may reach 50 metres (about 160 feet) per second or more and do extensive damage to property and vegetation.
