Vertical velocity statistics in continental stratocumulus as measured by a94GHz radar

Doppler power spectra from a vertically pointing 94GHz cloud radar are used to retrieve the mean and turbulent components of the in-cloud vertically v elocities for a continental stratocumulus cloud field. Several horizontal s cales of motion in the mean velocity field are shown, including a wave-clou d feature seen in satellite photographs. A profile of vertical velocity var iance is computed for both a high reflectivity and a low reflectivity regim e. These profiles appear reasonable and agree well to similar statistics fr om an instrumented aircraft.
