CPOL Radar-Derived Drop Size Distribution Statistics of Stratiform and Convective Rain for Two Regimes in Darwin, Australia

Drop Size Distributions and Radar Observations of Convective and Stratiform Rain over the Equatorial Indian and West Pacific Oceans

Two-dimensional video disdrometer (2DVD) data were analyzed from two equatorial Indian (Gan) and west Pacific Ocean (Manus) islands where precipitation is primarily organized by the intertropical convergence zone and theMadden–Julian oscillation (MJO). The 18 (3.5) months of 2DVDdata fromManus (Gan) Island show that 1) the two sites have similar drop size distribution (DSD) spectra of liquid wa...

Vertical Profiles Of: Rain Drop Size Distribution & Radar Reflectivity Factor-rain Rate (z-r) Relation

A method for estimating rain rate and drop size distribution from polarimetric radar measurements

Polarimetric radar measurements are sensitive to the size, shape and orientation of raindrops and provide information about drop size distribution (DSD), canting angle distribution and rain rate. In this paper, we propose and demonstrate a method for retrieving DSD parameters for calculating rain rate and the characteristic particle size. The DSD is assumed to be a Gamma distribution and the go...

Sensitivity of the Estimated Monthly Convective Rain Fraction to the Choice of Z–R Relation

This study investigates the sensitivity of the estimated monthly convective rain fraction— that is, the percentage of the areal rain accumulation contributed by precipitation identified as convective—to variations of the Z–R parameters used in radar-based rainfall estimation. Accurate knowledge of the fractions of precipitation that are convective and stratiform is important for climatological ...
