Abstract

The measurement of the vertical profiles of rainfall parameters such as drop size distribution, rain rate, liquid water content, fall velocity and radar reflectivity were carried out using Micro Rain Radar at Akure Lat 5° 15E, long 7 15N in South- Western Nigeria. The vertical distributions of these parameters with heights are presented for 0 - 4800 m. The range gates for the measurement are 30 with a height step of 160 m. The variation of the drop size distribution, rain rate and liquid water content with height were evaluated. The correlation coeficient and theregression line equation was computed for each rain event. The highest rain rate and liquid water content were observed within the height range 0-6400 m. Results obtained shows a good correlation between the measured parameters, henceit shows that specific liquid water content increases with increasing rain rate for both stratiform and convective rain types in this part of the world.
