RISApplication of the Zhang–Gal-Chen Single-Doppler Velocity Retrieval to a Deep Convective Storm
Publisher: American Meteorological Society
Abstract: The Zhang?Gal-Chen single-Doppler velocity retrieval (SDVR) technique is applied to a multicell storm observed by three radars near the Orlando, Florida, airport on 9 August 1991. This dataset is unique in that 3-min volume ...
Analysis of the Gal-Chen–Zhang Single-Doppler Velocity Retrieval
Publisher: American Meteorological Society
Abstract: The authors present herein an analysis of a single-Doppler velocity retrieval (SDVR) technique whereby the unobserved wind components are determined from single-Doppler radar data. The analysis is designed to provide ...
The Influence of Helicity on Numerically Simulated Convective Storms
Publisher: American Meteorological Society
Abstract: A three-dimensional numerical cloud model is used to investigate the influence of storm-relative environmental helicity (SREH) on convective storm structure and evolution, with a particular emphasis on the identification ...
Local Adjustment of the Background Error Correlation for Surface Analyses over Complex Terrain
Publisher: American Meteorological Society
Abstract: The terrain between grid points is used to modify locally the background error correlation matrix in an objective analysis system. This modification helps to reduce the influence across mountain barriers of corrections to ...
A Cloud Climatology of the Southern Great Plains ARM CART
Publisher: American Meteorological Society
Abstract: Cloud amount statistics from three different sources were processed and compared. Surface observations from a National Centers for Environmental Prediction dataset were used. The data (Edited Cloud Report; ECR) consist of ...
A Fetch-Based Statistical Method to Bias Correct and Downscale Wind Speed over Unresolved Water Bodies
Publisher: American Meteorological Society
Abstract: AbstractThis paper presents a method to bias correct and downscale wind speed over water bodies that are unresolved by numerical weather prediction (NWP) models and analyses. The dependency of wind speeds over water bodies ...
Statistically and Dynamically Downscaled, Calibrated, Probabilistic 10-m Wind Vector Forecasts Using Ensemble Model Output Statistics
Publisher: American Meteorological Society
Abstract: AbstractA computationally efficient method is developed that performs gridded postprocessing of ensemble 10-m wind vector forecasts. An expansive set of idealized WRF Model simulations are generated to provide physically ...
The Impact of High-Resolution Sea Surface Temperatures on the Simulated Nocturnal Florida Marine Boundary Layer
Publisher: American Meteorological Society
Abstract: High- and low-resolution sea surface temperature (SST) analysis products are used to initialize the Weather Research and Forecasting (WRF) Model for May 2004 for short-term forecasts over Florida and surrounding waters. ...
Evaluation of a Wind-Wave System for Ensemble Tropical Cyclone Wave Forecasting. Part I: Winds
Publisher: American Meteorological Society
Abstract: computationally efficient method of producing tropical cyclone (TC) wind analyses is developed and tested, using a hindcast methodology, for 12 Gulf of Mexico storms. The analyses are created by blending synthetic data, ...
Evaluation of the National Hurricane Center’s Tropical Cyclone Wind Speed Probability Forecast Product
Publisher: American Meteorological Society
Abstract: A tropical cyclone (TC) wind speed probability forecast product developed at the Cooperative Institute for Research in the Atmosphere (CIRA) and adopted by the National Hurricane Center (NHC) is evaluated for U.S. ...
