A Polarimetric and Microphysical Investigation of Winter Storms
(2018-12)
The U.S. WSR-88D network has been upgraded to polarimetric capabilities, providing dual-polarization data for regions of the country never before sampled by polarimetric radar and allowing for an unprecedented view into ...
The Changing Hydroclimate of the United States Great Plains: Meteorological and Climatological Impacts on Water Resources
(2018-12-14)
In the United States Great Plains (GP), understanding precipitation variability is key in developing an understanding of the present and future availability of water in the region. Numerous studies have investigated the ...
Forecast Sensitivity to Observations using Data Denial and Ensemble-based Methods over the Dallas-Fort Worth Testbed
(2018-05)
The ‘Nationwide Network of Networks’ (NNoN) concept was introduced by the National Research Council to address the growing need for a national mesoscale observing system. Part of this growing need is the continued advancement ...
A LAGRANGIAN PERSPECTIVE OF MESOCYCLONES AND DOWNDRAFTS IN OBSERVED AND NUMERICALLY SIMULATED SUPERCELLS
(2018-05)
On 29 May 2004, a high-precipitation supercell thunderstorm developed in western Oklahoma and produced tornadoes during almost every distinct mesocyclone cycle over a six-hour period. The storm was exceptional in its size, ...
The Great Plains Nocturnal Low-Level Jet: Spatial and Temporal Evolution
(2018-12)
The nocturnal low-level jet (NLLJ) is a maximum in the vertical wind profile often occurring in the lowest 1-km of the atmosphere during the overnight hours in the Great Plains of the United States. This wind maximum has ...
Observations and Simulations of Moisture Changes Occurring Around Sunset at the ARM Climate Research Facility
(2018-05-11)
Each summer, the U.S. Southern Great Plains (SGP) hosts a variety of ingredients (e.g. moisture, shear, instability, and lift) critical to understanding the life-cycle of deep, moist convection. Past studies have primarily ...
The Use of Polarimetric Radar Data for Informing Numerical Weather Prediction Models
(2018-05-11)
The explicit prediction of convective storms using storm-scale models has recently become a reality. Radar data is a crucial source of information about the microphysical and kinematic properties of convection at the ...
