On the collision of drops in turbulent clouds
WebCalifornia Institute of Technology Web31 de mar. de 1997 · In heterogeneous clouds the collision rates are increased, and the effects due to the inertia of the drop soon become predominant. The effect of turbulence in causing collisions between unequal drops becomes comparable with that of gravity when e is about 2000 cm^2 sec^(−3).
