GEOLOGY

Detailed explanation-1: -Tornadoes can often precede or succeed a storm, feeding off on the warm, moist air around the storm. The thunderstorm structure that houses the rotating updraft of wind, which can produce other phenomena like hail, is called a supercell.

Detailed explanation-2: -Supercell thunderstorms are a special kind of single cell thunderstorm that can persist for many hours. 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. Supercells are also known to produce extreme winds and flash flooding.

Detailed explanation-3: -Thunderstorms are known to occur in almost every region of the world, though they are rare in polar regions and infrequent at latitudes higher than 50° N and 50° S. The temperate and tropical regions of the world, therefore, are the most prone to thunderstorms.

Detailed explanation-4: -When warm, moist air collides with cold, dry air, tornadoes emerge. Generally, thunderstorms form when cooler, denser air is pushed over warmer air which is the cause of tornadoes. Updrafts are caused by warm air rising through the cold air. Whenever the wind strength or direction changes, the updraft begins to rotate.

Detailed explanation-5: -Often called “popcorn” convection, single-cell thunderstorms are small, brief, weak storms that grow and die within an hour or so. A multi-cell storm is a common, garden-variety thunderstorm in which new updrafts form along the leading edge of rain-cooled air (the gust front). More items
