An Evaluation of Radar- and Satellite-Data Based Products to Discriminate Between Tornadic and Non-Tornadic Storms
(2017-12)
Severe weather, and specifically tornadoes, can pose a significant threat to property and human life. Tornadic storms have been extensively studied using radar observations for decades, and some more recent studies have ...
Characteristics of the 2011-2016 California Drought
(2017-05-13)
The recent California drought persisted for five years from 2011-2016 and was the worst drought in recent memory. Previous studies have established that this drought was marked by low but not unprecedented rainfall coupled ...
Quantifying Precipitation Efficiency and Drivers of Excessive Precipitation in Post-Landfall Hurricane Harvey
(2019)
Hurricane Harvey produced widespread rainfall amounts over 1000 mm in portions of Southeast Texas, including Houston from 26-31 August 2017. The highly efficient and prolonged warm rain processes associated with Harvey ...
In-Situ Measurements and Remotely Sensed Estimations of Surface Fluxes over the Southern Great Plains of the United States
(2016-12)
Evapotranspiration (ET) is an important variable in the hydrologic cycle. As such, improved understanding of the spatial and temporal variability of ET is critical to weather and climate analysis and prediction, water ...
Evolution of Specific Differential Phase in Squall Lines and Corresponding Lightning Channels
(2017-08-01)
Dual-polarimetric radar products have been used in observing changes and persistence of thunderstorm electric fields in relation to lightning discharges. One such product, specific differential phase (KDP), is valuable ...
The "U-Tube": An improved aspirated temperature system for mobile meteorological observations, especially in severe weather
(2012)
The ability to obtain quality air temperature measurements in and around
thunderstorms is often problematic, and even more challenging from a moving platform
such as a ground-based vehicle. Since the original Verification ...
Observing system simulation experiment studies on the use of small UAV for boundary-layer sampling
(2018)
A long-desired component to the U.S. operational observing systems is the capability to measure vertical profiles of wind, temperature and moisture in the lower troposphere at high spatial and temporal resolution. This ...
Observations of Tropical Cyclone Vortex Rossby Waves and Their Role in Inner Core Rainbands
(2016-08-12)
Vortex Rossby Waves (VRWs) are hypothesized to exist in tropical cyclones (TCs), acting as an axisymmetrizing mechanism to the inner core TC flow and restored by the radial gradient of storm vorticity. In addition, they ...
Synoptic and Mesoscale Analysis of the 2015 Southern Great Plains Flash Pluvial
(2019-08)
During May and June of 2015, the Southern Great Plains (SGP) of the United States experienced numerous heavy rainfall and flooding events. The immense amount of rainfall (in excess of 80 cm) over a short period had tremendous ...
The Effects of Terrain on an Idealized Tornado using a Large-Eddy Simulation
(2019-08-01)
Tornado structure is known to be sensitive to the characteristics of near-surface inflow, which in turn is affected by inhomogeneities in surface features. Many observational studies such as VORTEX-SE have identified ...
