In rain big raindrops are more oblate and they fall faster thern smaller onse. When turbullence occurs, droplets of different diameters, that otherwise would fall with different velocities, get the same speed due to mixing caused by turbulence. The turbulence with determind intencity E involves into motion rsindrops, which diameters are less than certain diameter. Model we present in this paper let us calculate the relationships between differential Doppler velocity and turbulence intencity. Obtained relationships shows that differential Doppler velocity and intencity of turbulence are negatively correlated.
