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 […]

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 […]

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 […]
