Vertical velocity statistics in continental stratocumulus as measured by a 94GHz 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 velocities for a continental stratocumulus cloud field. Several horizontal scales of motion in the mean velocity field are shown, including a wave-cloud feature seen in satellite photographs. A profile of vertical velocity variance is computed for both a high reflectivity and a low reflectivity regime. These profiles appear reasonable and agree well to similar statistics from an instrumented aircraft.
