Physicists develop new rain prediction formula

Physicists in Israel have developed a new formula for predicting when clouds will spew forth rain. The trick, it seems, is all in the cloud turbulence. The more turbulence, the greater likelihood small droplets will smack into each other and form larger, heavier drops that fall to earth. Clouds are formed by warm water vapors rising to the sky. When a cloud cools, the vapors condense into droplets that increase in size and are eventually pulled back to earth by gravity, causing rain. Simple as this cycle may sound, when and where exactly the rain will fall is extremely difficult to predict.
