Convective Meteorology (Mesoscale Dynamics) Meteorological Benefits of Rapid-Scanning, Dual-Polarization Radar for Hail Producing Storms Laura Shedd Friday, March 25 3:00 PM NWC 5600 Hailstorms continue to be one of the leading economic natural hazards in the United States, amounting to ten billion dollars in damage, on average, annually. Radar technology has continued to prove to […]

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 […]

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 […]

Convective Meteorology (Mesoscale Dynamics) Investigations into the Poor Representation of the 10 August 2020 Midwest Derecho in Operational Numerical Models Jason Chiappa Friday, February 18 03:30 PM Join Google Meet The 10 August 2020 Midwest Derecho was the costliest thunderstorm disaster in modern US history, with damage estimates of ~$11.8 billion. However, most operational model forecasts […]

Convective Meteorology (Mesoscale Dynamics) Low Level Stability Analysis of Observed Supercell Environments Madeline Diedrichsen Friday, February 11 03:00 PM Google Meet Lapse rates have long been used to quantify the stability of the environment and aid in the prediction of thunderstorms. Low level lapse rates (0-1 km and 0-3 km) specifically have become a tool […]

Convective Meteorology (Mesoscale Dynamics) A Novel Technique to Correct Debris-Related Bias in Velocity Measurements from Tornadoes Morgan Schneider Friday, February 4 3:30 PM Join Google Meet: https://meet.google.com/iru-ggiv-afj Debris centrifuging in tornadoes is known to cause bias in radar measurements of tornadic wind speeds.  Debris presence in a radar volume is associated with anomalous radial divergence, […]

Convective Meteorology (Mesoscale Dynamics) Seminar Simulated WSR-88D Observations of the Streamwise Vorticity Current Austin Dixon Friday, February 4th 3:00 pm Join Google Meet: https://meet.google.com/iru-ggiv-afj   In recent years, the streamwise vorticity current (SVC) has been linked to supercellular tornado genesis. While this fact is interesting scientifically, it is only beneficial to operational predictability if identification […]

Convective Meteorology (Mesoscale Dynamics) Intercomparisons of Geostationary Lightning Mapper with ABI and MRMS Datasets Kevin Thiel Friday, January 28 3:00 PM Virtual Lightning observations from the GOES-R Geostationary Lightning Mapper (GLM) provides a new view of convection for the forecasting and severe storms research communities. As an optical sensor, the GLM is able to provide […]
