Development and validation of a sodar simulator for atmospheric boundary layer characterization
(2014-05-09)
A sodar simulator capable of producing time-series data emulating sodar signals
has been developed and tested. The atmospheric elds used to populate the sodar
simulator are taken from output of a large eddy simulation ...
Variability of Tropical Cyclones in the Philippines
(2014-05-09)
The massive impacts of tropical cyclones (TCs) on the Philippines are well known. This study provides an improved understanding of TC activity in the country, allowing improved risk mitigation strategies that possibly can ...
Polarimetric Radar Observations and Numerical Simulations of Tornadic Debris
(2014-05-09)
Tornadic debris are critical aspects of tornado studies because airborne debris pose significant threats to life and property, and debris often dominate backscattered radar signals, causing biased Doppler velocity measurements. ...
Atmospheric Moisture Transport Associated with the West African Monsoon System: An Observational Study and Evaluation of a WRF Dynamical Downscaling Simulation
(2014-05-09)
The intraseasonal variability of the low-level atmospheric moisture transport and its divergence associated with the West African monsoon (WAM) has been investigated for the 1960-2008 period using the NCEP-NCAR reanalysis ...
Observational and model analyses of the Oklahoma City urban heat island
(2014-05-09)
To date, much of the current understanding of the impacts of urban areas on atmospheric processes results from a number of field programs. Between 28 June and 31 July 2003, a vast array of instrument systems collected ...
Coupling the Advanced Regional Prediction System and the Discrete Event Specification Fire Spread Model to Predict Wildfire Behavior
(2014-05-09)
The cost of wildfire suppression in the United States has risen dramatically over the last 20 years. As the interface between wildland and urban areas expands, increased emphasis is being placed on rapid, efficient deployment ...
The formation of small-scale atmospheric vortices via horizontal shearing instability
(2014-12-12)
Motivated by recent high-resolution observations of small-scale atmospheric vortices along near-surface boundaries, this study presents a series of simulations that attempt to replicate the dynamics of the dryline and ...
Moisture and Thermal Characteristics of Southern Plains Ice Storms: Insights from a regional climatology and high-resolution WRF-ARW sensitivity study
(2014-08-15)
Winter storms, including snowstorms and ice storms, are infrequent in the Southern Great Plains of the United States (SGP), but can produce significant hazard and socioeconomic disruption. During 2000-2010, several severe ...
Estimating and Mitigating Errors in Dual-Polarization Radar Attenuation Correction
(2014-12-12)
Correction for rain attenuation is an important data quality issue when using data collected by radars operating at attenuating wavelengths, specifically C and X bands. Such issues are especially important for quantitative ...
ENSEMBLE KALMAN FILTER METHODS FOR CONVECTIVE-SCALE RADAR DATA ASSIMILATION AND MULTI-SCALE DATA ASSIMILATION OF THE 13 JUNE 2010 TORNADIC SUPERCELL ENVIRONMENT
(2014-08-15)
Ensemble data assimilation at convective-scales will need to solve a number of scientific and technical issues prior to being usable for operational numerical weather prediction. This research contributes to this goal by ...
