Answer to Question 1

All thunderstorms need three basic ingredients: 1 ) moist surface air; 2 ) a conditionally unstable atmosphere; and 3 ) a forcing mechanism, or trigger, that forces the air to rise. Potential forcing mechanisms are: random, turbulent eddies that lift small bubbles of air; unequal heating at the surface; the effect of terrain (such as small hills) or the lifting of air along shallow boundaries of converging surface winds; diverging upper-level winds, coupled with converging
surface winds and rising air; large-scale uplift along mountain barriers or gently rising terrain; or warm air rising along a frontal zone. Usually, several forcing mechanisms work together with vertical wind shear to generate thunderstorms.
