On May 13th, NC State student Keith Sherburn completed his M.S. defense – Improving the Understanding and Forecasting of Severe High Shear, Low CAPE Environments. This work was supported by the CSTAR Program with NOAA Grant NA10NWS4680007.
Keith’s presentation summarized much of his research into the climatology of High Shear, Low CAPE (HSLC) convection and improving the forecasting of HSLC significant severe convection including:
• background on why High Shear, Low CAPE (HSLC) severe convection is such a critical forecasting problem
• summary of his research data and methods
• environmental climatology
• development of new forecasting techniques and parameters including the Severe Hazards in Environments with Reduced Buoyancy (SHERB) parameter
• verification of several formulations of the SHERB parameter
• summary and future work
This research is highly relevant to NWS operations and was a collaborative project between NC State University, nearly a dozen WFOs, and the Storm Prediction Center. The presentation is available to NOAA Google drive account holders at this link.
