GEOLOGY

Detailed explanation-1: -Tornado formation typically needs the four ingredients: shear, lift, instability, and moisture. Wind shear is the most important factor that plays into the creation of tornadoes. When there is wind shear, sometimes these winds begin to roll into a horizontal column of air.

Detailed explanation-2: -Formation Ingredients 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: -In order for a thunderstorm to form, there are three basic ingredients that are essential, and are what we look for to provide a severe weather forecast. These three ingredients include moisture, rising unstable air, and a lifting mechanism. Moisture: A moisture supply is essential, of course.

Detailed explanation-4: -Wind shear is the change in wind speed and/or direction with height. Directional wind shear is the change in wind direction with height. In the image below, the view is looking north. The wind near the surface is blowing from the southeast to the northwest.

Detailed explanation-5: -There are three basic ingredients needed for thunderstorm development: moisture, an unstable atmosphere, and some way to start the atmosphere moving.
