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 uncoupled surface layer at the Crosstimber Micronet
(2006)
One of the greatest challenges faced by weather forecasters is the large spatial variability of temperature that occurs at small scales, particularly on clear nights with light wind. The physical processes that create this ...
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 ...
Rawinsonde Observations of Supercell-Environment Interactions
(2016-12)
The Mesoscale Predictability Experiment (MPEX) in 2013 and Mini-MPEX in 2016 used mobile soundings to observe the near-storm environments of springtime Great Plains convection. Together, the projects collected over 100 ...
A Two Part Study in the Evaluation of Quantitative Precipitation Forecasts from Convection-Allowing Models
(2017-12)
Previous studies examining convection-allowing models (CAMs), as well as NOAA/Hazardous Weather Testbed Spring Forecasting Experiments (SFEs) have typically emphasized “day 1” (12-36 h) forecast guidance. These studies ...
Kinematics, Thermodynamics, and Microphysics of the 25-26 June 2015 Kansas MCS during PECAN
(2018-05)
This case study analyzes a nocturnal mesoscale convective system (MCS) that was observed in northeast Kansas as part of the Plains Elevated Convection at Night (PECAN) field experiment on 25-26 June 2015. Over the course ...
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 ...
