Convective Meteorology (Mesoscale Dynamics) Development of a Radar Simulator and Statistical Techniques to Compare Weak and Strong Tornadic Supercells in Very High-Resolution Numerical Simulations Rachael N. Cross Friday, April 22 3:00 PM NWC 5600 Not only are supercells responsible for the majority of observed tornadoes, but they produce the strongest and longest-lived tornadoes. While there […]
Convective Meteorology (Mesoscale Dynamics) Observing System Simulation Experiments using the Warn-On Forecast System and a Passive, Multistatic Radar Network for the 7 May 2020 Northern Texas Hail-Producing Supercell Angela Mose Friday, April 22 03:00 PM NWC 5600 The Warn-On Forecast System (WoFS) is a rapid assimilation, storm-scale, convection-allowing ensemble that aims to provide watch-to-warning guidance […]
Convective Meteorology (Mesoscale Dynamics) New insights into tropical cyclone tornadoes Ben Schenkel Thursday, April 21 3:30 PM Join Google Meet: meet.google.com/dsk-amsn-vbk Landfalling tropical cyclones often produce tornadoes that compound damage inflicted by other storm hazards (e.g., inland flooding). However, current conceptual models do not explain the order of magnitude variability in the number of tornadoes […]
Weather and Climate Systems Forecasting Subseasonal Extreme Precipitation in the Contiguous United States: Examining the Utility of Random Forests Ty Dickinson Wednesday, April 20 03:00 PM Join Google Meet: https://meet.google.com/dai-kdtr-gtz Extreme precipitation across multiple timescales is a natural hazard that poses a significant risk to life, with a commensurately large cost through property loss. This study […]
Boundary Layer, Urban Meteorology, and Land-Surface Processes The impact of surface heterogeneity on surface flux estimation in stable boundary layers using single column modeling Dominic Candela Monday, April 18 03:00 PM Join Google Meet The earth’s surface is naturally heterogenous resulting in varying distributions of surface temperature, surface moisture, and aerodynamic roughness. The contrast in […]
Convective Meteorology (Mesoscale Dynamics) Examining Meteorological Benefits of Rapid-Scan, Dual-Polarization, All-Digital PAR Observations for Detecting Tornado Formation and Intensification Brandon Cohen Friday, April 15 03:00 PM Phased array radar (PAR) is widely considered the future for a replacement to the current operational radar network, NEXRAD. In particular, an all-digital operational PAR network offers a range […]
Weather and Climate Systems Assessing Precipitation Delineation Capabilities of Spaceborne Radars Maresa Searls Wednesday, April 13 03:00 PM Online Precipitation is a primary source of freshwater, is a component of multiple Earth cycles, and has important impacts from natural hazards. Knowing when, where, and how much precipitation is falling is crucial for understanding Earth’s global […]
Convective Meteorology (Mesoscale Dynamics) 14 April 2018 Shreveport-Bossier City, Louisiana QLCS Tornadoes: A Study of Tornadic Mesovortices and Their Lifecycles Alec Prosser Monday, April 11 03:30 PM NWC 5600 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, […]
Convective Meteorology (Mesoscale Dynamics) Detecting Above-Anvil Cirrus Plumes on a Pixel Scale Using Deep Learning Amanda Burke Friday, April 8 03:30 PM Online In satellite imagery, above-anvil cirrus plumes (plumes for short) are the strongest indicator of potentially significant severe weather, appearing on average 30 minutes before severe weather is reported. Real-time plume identification could […]
Convective Meteorology (Mesoscale Dynamics) Turbulent Supersaturation Fluctuations and Cloud Droplet Spectral Broadening observed during HI-SCALE and CACTI Yayun Qiao Friday, April 8 03:00 PM NWC 5600/ online Cloud droplet spectral broadening is one of the unsolved problems in the warm rain processes, and several hypotheses have been proposed, including the influence of turbulence and aerosol.
