要約

In rain big raindrops are more oblate and they fall faster then smaller ones. When turbulence 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 determined intensity ε involves into motion raindrops, which diameters are less than certain diameter DL. Model we present in this paper let us calculate the relationship between differential Doppler velocity and turbulence intensity. Obtained relationship shows that differential Doppler velocity and intensity of turbulence are negatively correlated.
