Data collected during the Indo-Soviet Monsoon-77 expedition are used to determine quadratic expressions for the universal constants A and B, as functions of the stability parameter, p. A quadratic expression has also been obtained for u*, in terms of the surface wind u,. It is shown, from the mean values of q and en, that the entire area covered by the expedition could be divided into four regions around the point 13"N, 78" E. The mean thermal characteristic of each region differs. It is shown that the northeastern quadrant is most favourable for the sustenance of a tropical storm once it has formed.

Seventy years pentad rainfall data for the southwest monsoon of India (June-September) of Bombay have been examined for their precipitation patterns using statistical techniques. It is found that the character of one pentad has an influence on the character of the following pantad. Further, there is slight tendency for wet pentads to be followed by further wet pentads. There is no tendency for dry period to be further followed by further dry period.
