Effect of High-Resolution Meteorological Forcing on Nearshore Wave and Current Model Performance
(American Meteorological Society, 2013)ccurate representation of wind forcing and mean sea level pressure is important for modeling waves and surges. This is especially important for complex coastal zone areas. The Weather Research and Forecasting (WRF) model ... -
C-Band Polarimetric Radar QPE Based on Specific Differential Propagation Phase for Extreme Typhoon Rainfall
(American Meteorological Society, 2013)o obtain accurate radar quantitative precipitation estimation (QPE) for extreme rainfall events such as land-falling typhoon systems in complex terrain, a new method was developed for C-band polarimetric radars. The new ... -
The Importance of Accurately Measuring the Range Correlation for Range-Oversampling Processing
(American Meteorological Society, 2012)fundamental assumption for the application of range-oversampling techniques is that the correlation of oversampled signals in range is accurately known. In this paper, a theoretical framework is derived to quantify the ... -
Application of a Bayesian Classifier of Anomalous Propagation to Single-Polarization Radar Reflectivity Data
(American Meteorological Society, 2013)naïve Bayes classifier (NBC) was developed to distinguish precipitation echoes from anomalous propagation (anaprop). The NBC is an application of Bayes's theorem, which makes its classification decision based on the class ... -
Impact from a Volumetric Radar-Sampling Operator for Radial Velocity Observations within EnKF Supercell Assimilation
(American Meteorological Society, 2012)aximizing the accuracy of ensemble Kalman filtering (EnKF) radar data assimilation requires that the observation operator sample the model state in the same manner that the radar sampled the atmosphere. It may therefore ... -
Detection of Optically Thin Mineral Dust Aerosol Layers over the Ocean Using MODIS
(American Meteorological Society, 2013)nalyses show that several existing Moderate Resolution Imaging Spectroradiometer (MODIS) dust detection techniques, including an approach based on simple brightness temperature difference thresholds, the D-parameter method, ... -
Ground-Based Observations and Modeling of the Visibility and Radar Reflectivity in a Radiation Fog Layer
(American Meteorological Society, 2012)he development of a radiation fog layer at the Cabauw Experimental Site for Atmospheric Research (51.97°N, 4.93°E) on 23 March 2011 was observed with ground-based in situ and remote sensing observations to investigate the ... -
A Surface Mooring for Air–Sea Interaction Research in the Gulf Stream. Part II: Analysis of the Observations and Their Accuracies
(American Meteorological Society, 2012)surface mooring was deployed in the Gulf Stream for 15 months to investigate the role of air?sea interaction in mode water formation and other processes. The accuracies of the near-surface meteorological and oceanographic ... -
Partial Beam Blockage Correction Using Polarimetric Radar Measurements
