What are some of the meteorological or atmospheric conditions that favor the development of severe thunderstorms? The difference between ordinary cell thunderstorms and severe thunderstorms‚ is that severe thunderstorms “produce at least one of the following: large hail with a diameter of at least one inch‚ surface wind gusts of

you decrease in relative humidity. If you had a hot summer day and a steady dew point; you would actually had a lower relative humidity. 3. In what ways are severe thunderstorms different from ordinary cell thunderstorms? What are some of the meteorological or atmospheric conditions that favor the development of severe thunderstorms? The basics of a thunder storm are fairly easy‚ because they consist of thunder‚ lightning‚ winds‚ rain and heavy hail at times. “The storm itself may be a single

destruction. Chiefly‚ there are different causes for a tornado. “An MCS is a cluster of thunderstorms that act as a system and often produce severe weather” (Bluestein). Many past thunderstorms formed super cells; super cells contained fast-spinning air called a mesocyclone. “The air that rises from the ground in the vortex creates low air pressure near the ground” (Bluestein). Many tornado-forming thunderstorms have formed in low-pressured areas. “You need warm‚ moist air from the Gulf of Mexico

generated inside the thunderstorm. 2. How are tornadoes formed? Tornadoes form in unusually violent thunderstorms when there is sufficient instability‚ and wind shear present in the lower atmosphere. Instability refers to warmer and more humid than usual conditions in the lower atmosphere‚ and possibly cooler than usual conditions in the upper atmosphere. Wind shear in this case refers to the wind direction changing‚ and the wind speed increasing‚ with height. 3. Parts of a thunderstorm a) Updrafts/Downdrafts-

A tornado is defined as a violently rotating column extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of two hundred and fifty miles per hour or more. Damage paths can be more than one mile wide and fifty miles long. In an average year‚ eight hundred tornadoes are reported nationwide‚ resulting in eighty deaths and over one thousand five hundred injuries. In the body of my essay‚ I will tell you about types of tornadoes
