Abstract: The Shared Mobile Atmospheric Research and Teaching radars observed five landfalling tropical cyclones (TCs) from 2016-2018. The observations were largely targeted toward understanding asymmetric convective and dynamic processes. Such processes are thought to lead to the intensification of the TC primary tangential circulation, affect the distribution of extreme winds, and promote locally heavy rainfall. Relative to more traditional, aircraft-based analyses, the SMART radar datasets afford continuous high temporal and spatial resolution observations. These observations can be used to compliment and extend aircraft observed and numerically simulated TC processes.

Weather and Climate Systems Seminar A Climatology of TPVs in the ERA-Interim Dataset Dylan Lusk Wednesday, February 20th 3:00pm/NWC 5600 Tropopause Polar Vortices, or TPVs, are long-lived, coherent vortices located primarily on the tropopause over polar regions. These upper level features have been identified as important dynamical predecessors to surface cyclogenesis for some time, […]

Title: Regional Characteristics of Flash Droughts Across the United States Abstract: Flash droughts are characterized by the rapid onset and development of drought conditions. When a combination of extreme atmospheric anomalies (such as lack of rainfall, higher surface temperatures, higher surface wind speeds, and higher vapor pressure deficient) persist for several weeks, rapid depletion […]

Weather and Climate Seminar Characterization of the Structure of Tropopause Polar Vortices using Remote Sensing Ryan Pajela Wednesday, January 30th 3:00pm/NWC 5930 Tropopause polar vortices (TPVs) are atmospheric coherent vortex-like structures originating poleward of the jet stream and exhibit a closed circulation of the wind along the 2-PVU dynamic tropopause. Cyclonic […]
