Prediction of convective rainfall using multi-technique observations

Nowcasting of rain amount is extremely essential in various fields of life. In this paper, we have shown that monitoring of brightness temperature at 31.4 GHz, the frequency having strong absorption due to liquid water, can give an estimate of rain accumulation with a prediction efficiency of ~ 80 % and a lead time of 75 minutes. It has also been observed that atmospheric electric field also shows definite changes before rain the magnitude of which can be related with the rainfall amount.
