GEOLOGY

Detailed explanation-1: -Because wind is invisible, it is hard to see a tornado unless it forms a condensation funnel made up of water droplets, dust and debris. Tornadoes can be among the most violent phenomena of all atmospheric storms we experience.

Detailed explanation-2: -The key atmospheric ingredients that lead to tornado potential are instability-warm moist air near the ground, with cooler dry air aloft and wind shear-a change in wind speed and/or direction with height.

Detailed explanation-3: -Tornadoes are formed by a combination of atmospheric instability and wind shear. Instability occurs when warm, moist air is wedged under drier, cooler air aloft. This warm air rises, causing the intense updrafts and downdrafts seen in strong thunderstorms-the incubators of tornadoes.

Detailed explanation-4: -The pressure inside a tornado is less than the surrounding atmospheric pressure. That pressure differential causes flow into the tornado of objects such as cars, mobile homes, other structures and more (reference Dorothy and Toto).
