Measurements of raindrop-size distributions from dual- polarization spectral observations
Rainfall radar observations depend on underlying raindropsize distributions. Since rain rates retrieval from radar measurements is problem of current interest there is great importance in independent measurements of naturally occurring drop-size distributions. Often in situ measurements of raindrop size distributions are performed using disdrometers (Bringi et al. 2003). Despite wide acceptance...
متن کاملNonparametric Estimation of Raindrop Size Distributions from Dual-Polarization Radar Spectral Observations
This paper presents a method to retrieve raindrop size distributions (DSD) from slant profile dualpolarization Doppler spectra observations. It is shown that using radar measurements taken at a high elevation angle raindrop size distributions can be retrieved without making an assumption on the form of a DSD. In this paper it is shown that drop size distributions can be retrieved from Doppler p...
متن کاملRaindrop axis ratios and size distributions in Florida rainshafts: an assessment of multiparameter radar algorithms
Eleven penetrations of rainshafts by the University of Wyoming King Air (WKA) aircraft equipped with a twodimensional (2-D) optical array probe are studied in coordination with multiparameter radar measurements from the National Center for Atmospheric Research (NCAR) CP-2 radar collected in a multicellular storm that occurred on August 8, 1991, of the Convective and Precipitation/Electrificatio...
متن کاملRaindrop size distributions and radar reflectivity–rain rate relationships for radar hydrology*
The conversion of the radar reflectivity factor Z (mm6 m-3) to rain rate R (mm h-1) is a crucial step in the hydrological application of weather radar measurements. It has been common practice for over 50 years now to take for this conversion a simple power law relationship between Z and R. It is the purpose of this paper to explain that the fundamental reason for the existence of such power la...
متن کاملThe Modelled Raindrop Size Distribution of Skudai, Peninsular Malaysia, Using Exponential and Lognormal Distributions
This paper presents the modelled raindrop size parameters in Skudai region of the Johor Bahru, western Malaysia. Presently, there is no model to forecast the characteristics of DSD in Malaysia, and this has an underpinning implication on wet weather pollution predictions. The climate of Skudai exhibits local variability in regional scale. This study established five different parametric express...
