✦ Synopsis

The velocity of a cloud is the velocity of the air in which it floats, except in the case of a stationary type-crest cloud, banner cloud, e* cetera--or a billow cloud. With these exceptions, it therefore is approximately the gradient velocity at the cloud level, which varies with altitude, latitude, temperature, and pressure distribution.

Average values, observed at certain places, are given in the following table, also copied from Hann's" Lehrbuch der Meteorologie "" Average Wi~d Velocity in Metres t~er Second.
