Assessing the impact of non-conventional observation types on high-resolution 3DVAR analyses and ARW-WRF forecasts
(2016-12)
This work looks at the impact on high-resolution analyses and forecasts of several non-conventional data types available within the Dallas Fort Worth (DFW) Urban Testbed. A major focus is an evaluation of the added value ...
Verification of 10-Meter Wind Forecasts from NSSL-WRF in Predicting Severe Wind-Producing MCSs
(2016-12-16)
Predicting convective winds associated with mesoscale convective systems (MCSs) remains a major challenge for operational severe weather forecasters. To assess the performance of the Weather Research and Forecasting Model ...
A Study Of The Electrical, Microphysical, And Kinematic Properties Of The 29 May 2012 Kingfisher Supercell
(2014)
A supercell thunderstorm formed as part of a cluster of severe storms near Kingfisher, OK on 29 May 2012 during the Deep Convective Clouds & Chemistry (DC3) experiment. This storm produced 5” hail, an EF-1 tornado, and ...
Doppler Radar Analyses of Tornadic Supercells on 19 May 2013
(2016-05-13)
On 19 May 2013, two supercells moved through central Oklahoma and produced seven tornadoes, including one of EF-3 and one of EF-4 intensity. High temporal and spatial resolution observations were collected in both strong ...
Rapid-scan, polarimetric, mobile, Doppler-radar observations of the formation, evolution, and structure of the El Reno tornado of 31 May 2013
(2016-10)
On 31 May 2013, the mobile, Rapid-scan, X-band, Polarimetric (RaXPol) radar collected a high spatial and temporal resolution dataset documenting the genesis, intensification, and dissipation of a tornado that caused EF-3 ...
Large Scale and Local Influences on the Occurrence and Maintenance of Liquid Bearing Clouds over the Greenland Ice Sheet
(2016)
Arctic liquid bearing clouds (LBCs) have a large impact on the surface radiation and cryospheric mass budgets. Their effect on the surface radiation budget is a combination of two competing processes. First, they can ...
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 ...
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 ...
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 ...
