Weather and Climate Systems Sensitivity of the February 2021 U.S. Cold-Air Outbreak to Tropopause Polar Vortex Intensity Tomer Burg Wednesday, March 23 3:00 PM Tropopause Polar Vortices (TPVs) are coherent vortices along the tropopause, with cyclonic TPVs identified by a local minimum in temperature and local maximum in potential vorticity along the dynamic tropopause. TPVs […]
Weather and Climate Systems Hurricane Laura (2020): A Comparison of Drop Size Distribution Moments Using Ground and Radar Remote Sensing Retrieval Methods Noah Brauer Wednesday, March 23 3:00 PM NWC Hurricane Laura was the strongest hurricane to make landfall in Louisiana since 1969 with maximum sustained winds of 130 knots. One University of Oklahoma Shared […]
Convective Meteorology (Mesoscale Dynamics) Using Radiosonde Observations to Assess The ‘Three Ingredients’ Method to Forecast QLCS Mesovortices Max Ungar Friday, March 11 03:00 PM Quasi-Linear Convective System (QLCS) mesovortices have a propensity to produce impactful severe weather outcomes, including tornadoes and enhanced straight-line wind damage. Despite advances in understanding the origins of these meso-gamma scale […]
Weather and Climate Systems The Stratospheric Processes Influencing Cold Air Outbreaks in the Great Plains of the United States Oliver T Millin Wednesday, March 9 03:00 PM Join Google Meet! https://meet.google.com/hwd-ruyp-grx Wintertime cold air outbreaks (CAOs) are extreme cold events involving the displacement of cold air into the midlatitudes from a polar origin. CAOs in […]
Boundary Layer, Urban Meteorology, and Land-Surface Processes Ph.D. Candidate Brian R. Greene Monday, March 7 03:00 PM Join Google Meet http://meet.google.com/fcr-hokz-ubf The stable atmospheric boundary layer (SBL) has significant societal impacts ranging from pollution dispersion to wind energy production. For decades, SBL turbulence has proven challenging to measure, parameterize, simulate, and interpret for a variety […]
Convective Meteorology (Mesoscale Dynamics) The Impacts of Airmass, Vertical Motion and Mixing on the Microphysical Properties of Continental Boundary Layer Clouds Observed During RACORO Saurabh Patil Friday, March 4 03:00 PM Join Google Meet Boundary layer clouds comprising cumulus, stratus, and stratocumulus cover a large spatial extent and play a key role in regulating Earth’s […]
Convective Meteorology (Mesoscale Dynamics) Examining the Impacts of Assimilating Vertically Integrated Ice on two PECAN MCSs Rachel Miller Friday, March 4 3:00 PM Forecasting nocturnal mesoscale convective systems (MCSs) is challenging due to the poor handling of the timing and location of convection initiation (CI). This study investigates two nocturnal MCSs from the Plains Elevated […]
Convective Meteorology (Mesoscale Dynamics) 14 April 2018 Shreveport-Bossier City, Louisiana QLCS Tornadoes: A Study of Tornadic Mesovortices and Their Lifecycles Alec Prosser Friday, February 25 03:00 PM Mesoscale-gamma circulations that occur along the leading edge of mature Quasi-Linear Convective systems (QLCS) have been documented in literature for a number of years. In fact, numerical simulations […]
Weather and Climate Systems Forecasting the Forecast with Deep Learning Chris Rattray Wednesday, February 23 3:30 PM Global numerical weather prediction systems produce occasional significant drops in the accuracy of their forecasts often referred to as “forecast busts†in the literature. Despite recent efforts, understanding the causes of these forecast failures remains challenging, but essential. […]
Weather and Climate Systems Discussion and Analysis of the GridRad-Severe Dataset and Methodology Amanda Murphy Wednesday, February 23 03:00 PM Join Google Meet! https://meet.google.com/hwd-ruyp-grx Many studies have aimed to identify novel characteristics of storms that are indicative of current or future severe weather potential. Such fine-scale analyses are often limited to a handful of case […]
