On the Annual Rainfall Effect Governing the Relation between GMS-IR and Rainfall on the Ground in Southeast Asia

Abstract

It was found that the daily and 10-daily rainfall at a station corresponding to a given level of cold cloud cover fraction Fc=0.3 depend on the annual rainfall at the station. This dependence will be called as “Annual rainfall effect”. The effect indicates that the rainfall phenomena strongly reflects the local geographical, meteorological and other conditions that determine the amount of annual rainfall. The precision of regional as well as global estimates of precipitation would be improved by including the average annual rainfall in the estimation formulae.
