Abstract

Radar study of clouds has mostly been confined to that of convective clouds or precipitation-producing stratiform clouds. No such study appears to have been made of the non-precipitating clouds like altocumulus.

 

The high power radar CPS-9 at Safdarjung, New Delhi, has been receiving radar echoes from altocumulus clouds of cloudlet type and these have been under study. Two examples are presented here and discussed. Based on the radar parameters, the order of the smallest droplet size in altocumulus has been calculated and is found to be of the order 6u-8u and to be fairly independent of concentration of droplets in the cloud. The cellular structure of the cloud as revealed by PPI and RHI photographs confirms the idea of existence of Benard Cells drawn earlier on the basis of laboratory experiments and aeroplane flights.
