An analytical solution for raindrop evaporation and its application to radar rainfall measurements

Journal of Applied Meteorology | September 1, 2001| | Copyright

ABSTRACT

An analytical solution for the evaporation of a single raindrop is derived in this paper. Based on this solution, a parameter D* is defined as the diameter of the raindrop that just evaporates completely after falling through a certain distance in a prescribed environment. The parameter D* is then used for studying the modification of raindrop size distribution by evaporation in a steady, still atmosphere. The results for the Marshall-Palmer distribution are used to discuss errors caused by rain evaporation in radar rainfall measurements. Quantitative estimation of these errors, or ...
