Evaluation of the Warn-on-Forecast System with Doppler Lidar and Mobile Radiosondes from TORUS2019
(2020)
Doppler lidar and mobile radiosonde observations from the Targeted Observations with
Radars and UAS of Supercells 2019 (TORUS2019) eld project are compared to the environ-
mental guidance NSSL Warn-on-Forecast System ...
The Impact of the Madden-Julian Oscillation on Extreme Winter Weather in the United States
(2022-08)
Winter weather has substantial impacts on human activity, but it is challenging to predict more than 7-10 days in advance. Subseasonal-to-seasonal (S2S) prediction is a rapidly developing field of meteorology that could ...
ANALYSIS OF FLOW AND THERMODYNAMIC CHARACTERISTICS AT A SITE IN COMPLEX TERRAIN
(2018-08)
The goal of the Perdigão Field Experiment was to study atmospheric flows in complex terrain and to collect a high-quality dataset for the validation of meso- and micro-scale models. An Intensive Observation Period (IOP) ...
The Response of a Long-lived Mesoscale Convective System to Changes in Lower-Tropospheric Conditions
(2017-05)
Most continental regions experience an afternoon or evening maximum of convective activity, which is dominated by convection driven by surface heating. However, the Great Plains of North America experiences a nocturnal ...
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 ...
Examining the Vertical Structure of Hurricane Laura (2020) Using Azimuthal-Mean Vertical Profiles and an EOF Analysis
(2023-08-04)
The eyewall, inner rainband, and outer rainband regions of tropical cyclones (TCs) have been extensively studied, resulting in numerous conceptual models. While these conceptual models are insightful regarding basic-state ...
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 ...
Mesovortex-Induced Tornadoes: A Case Study of the 13 April 2018 Northwest Louisiana Quasi-Linear Convective System
(2022-12-16)
Mesoscale-gamma circulations occurring along the leading edge of Quasi-Linear Convective Systems (QLCS), and their propensity to produce tornadoes and straight-line wind damage has long been noted in literature. Furthermore, ...
