Abstract
Two aspects of radar-based measurement of convective rainfall over the
Transvaal Highveld are examined. Drop size distributions (DSDs) are studied in
order to quantify the effects of drop size distribution variability on the Z-R
relationship, and the area-time integral (ATI) method is investigated as a possible
means of radar rainfall measurement. Drop sorting effects are clearly evident in
convective rain with resultant DSDs having higher numbers of large drops and
causing Z-R derived rain rates to be overestimated. Abbreviation abstract)
