Understanding the Features and Mechanisms of the Great Plains Low-Level Jet in CMIP5 Models
(2016-12)
The Great Plains low-level jet (GPLLJ) is an important driver of precipitation and severe weather outbreaks over the U.S. Great Plains during the spring and summer. Therefore, it is extremely important that features of the ...
Observations of Cold Front Features at High Spatiotemporal Resolution Using the Atmospheric Imaging Radar
(2016-08-12)
Over the past 40+ years, cold front vertical structure has been studied for the
purpose of increased understanding of convection initiation and aviation safety. Traditional
scanning radars tend to not be well-suited for ...
Understanding and Predicting Nocturnal Convection Initiation using an Ensemble-based Multi-scale Data Assimilation System
(2016-08-12)
A nocturnal maximum in precipitation exists over the Great Plains during the summer. The initiation of nocturnal storms is notoriously difficult to forecast in numerical models due to the storms often involving interactions ...
Using Machine Learning to Predict Damaging Straight-line Convective Winds
(2016-08-12)
Thunderstorms, including straight-line (non-tornadic) winds, cause an average of over 100 deaths and $10 billion of insured damage per year in the United States. In the past decade machine learning has led to significant ...
Synoptic and Local Influences on a Summertime, Long-Lived, Mixed-Phase Cloud Event Over Summit, Greenland
(2016-08-12)
Long-lived, Arctic mixed-phase clouds play a crucial role in modulating the surface energy balance over the Greenland Ice Sheet. However, due to temporally and spatially inconsistent observations, little is known about the ...
Global Large-Scale Stratosphere-Troposphere Exchange in Modern Reanalyses
(2016-08-12)
Stratosphere-troposphere exchange (STE) has important and signi cant impacts
on the chemical and radiative properties of the upper troposphere and lower stratosphere.
This study presents a 15-year climatology of global ...
Bridging the NASA Global Precipitation Measurement and Soil Moisture Active Passive Missions: Variability of Microwave Surface Emissivity from both In-situ and Remote Sensing Perspectives
(2016-08-12)
The overland precipitation retrievals from satellite passive microwave (PMW) radiometer such as the Global Precipitation Mission (GPM) microwave imager (GMI) suffer from the contamination of observed brightness temperatures ...
