Abstract

Measurements o f clo ud drop ..ire spectra on non-preci pitating cumulus clouds, 1·2 km thick,
were made at differe nt levels o ver the Arabian Sea (maritime) and over r une (inland) regio n during the end of
the summer monsoo n seasons of 1973, 1974 and 1979.
The macimurn size of clo ud drops for the. Arabian Sea generally increased with height. while that for run e
JiJ not show a systematic change with height. At bot h the local ions. the total concentration o f drops decreased
with height. The maritime dist ributions were bimodal at all levels while those o..-er Punc were usually unimodal.
The average values of liquid water content. mean vo lume diameter. dispersion and conccnt rarion of drops with
diameter > 50 «m were a lin le greater and total concentration a little smaller over the maritime region as ' om'
pared to those over inland. The co ncentrations of drops with diameter < 14 ,...m and those > 78 I'm and the
ma ximum ~ i 7e were greater over Pune than o..er the sea. The ..'a riarions in cloud drop spectra and the clo ud
physical parameters over beth the locations are discussed.
