Thunderstorms And Tornadoes
Thunderstorms and tornadoes are severe local storms.
-
They are of short duration, occurring over a small area but are violent.
-
Thunderstorms are caused by intense convection on moist hot days.
-
A thunderstorm is a well-grown cumulonimbus cloud producing thunder and lightning.
-
When the clouds extend to heights where sub-zero temperature prevails, hails are formed and they come down as hailstorm.
-
If there is insufficient moisture, a thunderstorm can generate dust storms.
-
A thunderstorm is characterized by the intense updraft of rising warm air, which causes the clouds to grow bigger and rise to a greater height. This causes precipitation.
-
From severe thunderstorms sometimes spiraling wind descends like a trunk of an elephant with great force, with very low pressure at the center, causing massive destruction on its way. Such a phenomenon is called a tornado.
-
Tornadoes generally occur in middle latitudes.
-
The tornado over the sea is called water sprouts.
-
These violent storms are the manifestation of the atmosphere’s adjustments to varying energy distribution.
-
The potential and heat energies are converted into kinetic energy in these storms and the restless atmosphere again returns to its stable state.
