Abstract

In this paper, the authors attempt, in particular, to find functional relations between surface rainfall and Cloud Liquid Water (CLW), Precipitation Water (PW), and Latent Heat (LH) at the TRMM vertical profiling levels. The investigation shows strong correlations between rainfall and each of these parameters and a combination of all these. The study indicates that the functional relation at the closest TRMM profiling level to the Earth at 0-0.5km (and at all levels), can estimate rainfall accurately. So, the authors suggest designing and installing an instrument at say, 0.5km to measure the PW/CLW/ LH or all of the three parameters. This will estimate rainfall with excellent accuracy. Alternatively, the authors feel the need for establishing functional relations between the surface parameters say, surface pressure (SP), surface temperature (ST), and relative humidity (RH), and the upper-air parameters, viz. CLW, PW, and LH. Such relations will help to estimate rainfall at any location, in two steps- first estimating the upper-air parameters from the surface parameters and then surface rainfall from the latter.
