Abstract :
A discussion is given on the effect of wind on raindrops. It is shown that wind in itself cannot be a cause of raindrop canting. Vertical wind gradients are shown to produce a horizontal force on the drops, resulting in a canting angle. Calculations, based on a general model for wind gradients between 10 and 200 m for strong winds, show that canting angles of several degrees are possible.
