Rainfall Prediction using Soil and Air Temperature in a Tropical Station

摘要

An attempt is made to establish a linkage between soil and air temperature and south-west monsoon rainfall at Pillicode (12°12N,75°10E) a tropical station in north Kerala. The dependence of monsoon rainfall on pre-monsoon soil temperature decreases as the depth of the soil increases. A regression equation has been developed for the estimation of monsoon rainfall using pre-monsoon soil and air temperature. The results show that sub soil temperature along with air temperature can be used for forecasting the monsoon level.
