Investigation of Melting Layer for Convective Rain in Tropical Region

Abstract

Convective rain occurs quite often in tropical region, however, very little is known of the melting layer for convective rain. In this paper, the S band dual-polarization radar data are processed to identify the convective rain melting layer in the tropical country of Singapore. By studying and isolating the convective rain region, it is found out that among the three radar measurements of reflectivity, differential reflectivity, and cross-correlation coefficient, the crosscorrelation coefficient parameter is the most suitable indicator for convective rain melting layer detection. The reflectivity can be used to differentiate between stratiform rain and convective rain.
