Estimation of Ground-Level Reflectivity Factor in Operational Weather Radar Networks Using VPR-Based Correction Ensembles
(American Meteorological Society, 2014)n operational method is presented that corrects the bias of radar-based quantitative precipitation estimations (QPE) in radar networks that is due to the vertical profile of reflectivity (VPR) factor. It is used in both ... -
Stable Boundary Layer in Complex Terrain. Part II: Geometrical and Sheltering Effects on Mixing
(American Meteorological Society, 2014)he authors examine how terrain texture and topography influence nocturnal mixing rates. Local topographic curvature and site sheltering exhibit systematic influences on nocturnal heat and momentum fluxes and the near-surface ... -
Radar-Derived Statistics of Convective Storms in Southeast Queensland
(American Meteorological Society, 2015)he aim of this study is to examine the statistics of convective storms and their concomitant changes with thermodynamic variability. The thermodynamic variability is analyzed by performing a cluster analysis on variables ... -
Quantifying Surface Energy Fluxes in the Vicinity of Inland-Tracking Tropical Cyclones
(American Meteorological Society, 2013)ropical cyclones (TCs) typically weaken or transition to extratropical cyclones after making landfall. However, there are cases of TCs maintaining warm-core structures and intensifying inland unexpectedly, referred to as ... -
The Dual Wavelength Ratio Knee: A Signature of Multiple Scattering in Airborne Ku–Ka Observations

WRF–SBM Simulations of Melting-Layer Structure in Mixed-Phase Precipitation Events Observed during LPVEx
(American Meteorological Society, 2014)wo mixed-phase precipitation events were observed on 21 September and 20 October 2010 over the southern part of Finland during the Light Precipitation Validation Experiment (LPVEx). These events have been simulated using ... -
Impacts of Projected Climate Change over the Lake Champlain Basin in Vermont
(American Meteorological Society, 2014)he Lake Champlain basin is a critical ecological and socioeconomic resource of the northeastern United States and southern Quebec, Canada. While general circulation models (GCMs) provide an overview of climate change in ... -
Characteristics of 50–200-m Winds and Temperatures Derived from an Iowa Tall-Tower Network
(American Meteorological Society, 2014)imitations in skill of wind speed forecasts lead to conservative bids of wind-plant production in the day-ahead energy market and usually to an underutilization of wind resources. Improvements are needed in understanding ... -
Height Correction of Atmospheric Motion Vectors Using Satellite Lidar Observations from CALIPSO
(American Meteorological Society, 2014)tmospheric motion vectors (AMVs) provide valuable wind information for the initial conditions of numerical weather prediction models, but height-assignment issues and horizontal error correlations require a rigid thinning ... -
A Physically Based Algorithm for Non-Blackbody Correction of Cloud-Top Temperature and Application to Convection Study
