Abstract
This paper investigates the variability of raindrop size distribution (DSD) and particularly, the role of specific drop sizes in rain integral parameters at a tropical location. Rain DSDs for the years 2006-2007 at Ahmedabad (23°04′ N, 72°38′ E) have been measured using a Disdrometer. Variability of DSD is evaluated and its effect on the integral rain parameters like radar reflectivity, rainfall intensity and attenuation are examined. It is observed that drops with diameter around 4 mm contribute maximum to the radar reflectivity while drops having diameter 3 mm contribute maximum to the rainfall intensity for the present location. Further, a strong effect due to variability of critical drop diameter is observed on rain rate and rain attenuation but the effect is found to be less pronounced on radar reflectivity.
