Effective Dielectric Constants of Mixed-Phase Hydrometeors
Publisher: American Meteorological Society
Abstract: Melting snow, graupel, and hail are often modeled as uniform mixtures of air?ice?water or ice?water. Two-layered models have also been proposed in which the particle consists of a dry snow or ice core surrounded by water ...
Comparisons of Cross Sections for Melting Hydrometeors as Derived from Dielectric Mixing Formulas and a Numerical Method
Publisher: American Meteorological Society
Abstract: One of the impediments to the interpretation of radar signatures from the melting layer is the uncertainty over the dielectric mixing formula for ice-water mixtures. In the commonly used Maxwell Garnett mixing formula, the ...
A Feasibility Study for Simultaneous Estimates of Water Vapor and Precipitation Parameters Using a Three-Frequency Radar
Publisher: American Meteorological Society
Abstract: The radar return powers from a three-frequency radar, with center frequency at 22.235 GHz and upper and lower frequencies chosen with equal water vapor absorption coefficients, can be used to estimate water vapor density ...
Relationship between Horizontal Wind Velocity and Normalized Surface Cross Section Using Data from the HIWRAP Dual-Frequency Airborne Radar
Publisher: American Meteorological Society
