Differential Doppler Velocity: A Radar Parameter for Characterizing Hydrometeor Size Distributions
Publisher: American Meteorological Society
Abstract: Observations of Doppler-resolved spectra of differential radar reflectivity provide estimates of particle shapes as a function of their terminal velocity, and they can be derived by having the antenna at a significant ...
Effects of Initial and Boundary Conditions of Mesoscale Models on Simulated Atmospheric Refractivity
Publisher: American Meteorological Society
Abstract: adar ducting is caused by sharp vertical changes in temperature and, especially, water vapor at the top of the atmospheric boundary layer, both of which are sensitive to variations in the underlying surface conditions, ...
Using Continuous Ground-Based Radar and Lidar Measurements for Evaluating the Representation of Clouds in Four Operational Models
Publisher: American Meteorological Society
Abstract: The ability of four operational weather forecast models [ECMWF, Action de Recherche Petite Echelle Grande Echelle model (ARPEGE), Regional Atmospheric Climate Model (RACMO), and Met Office] to generate a cloud at the right ...
