Abstract

Frequency distributions of the heights of convective clouds observed in different regions in India during the hot weather and monsoon seasons have been investigated in order to study the growth mechanisms of such clouds. The study is based on the available radar data of heights of such clouds in five different regions in India, namely, around Bombay, Calcutta, Hyderabad, Gauhati and Delhi. During both the seasons, frequency distributions of the heights of the radar echoes of such clouds have been found to be lognormal in all the places except for larger height groups. The observed distributions suggest that convective clouds grow according to the law of proportionate effects. The deviation of the height distributions from lognormality at greater heights is attributed to the effect of the tropopause which inhibits vertical development of clouds.
