Dylan Lusk- Feb 20
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 […]

Validation of the FV3GFS and Future Plans for the NCEP Production Suite with Geoff Manikin- October 16th
ABSTRACT: In 2016, NCEP selected the Finite Volume 3 (FV3) dynamical core to be the cornerstone of its NWP efforts in the years ahead. The first step towards a Unified Forecast System (UFS) is the implementation of the FV3GFS which will become the operational global model in early 2019. This presentation explains the need for the UFS, examines objective and subjective results from real-time and retrospective testing of the FV3GFS, and discusses modeling plans going forward.
