FY09 GIMPAP Project Proposal Title Page Revised: October 31, 2008. Title : Aviation Weather Hazards Project Type : Product Development Status : Renewal Duration : 2 year Leads: Ken Pryor (SMCD/OPDB) Other Participants : Andrew Bailey (IMSG) . 2. Project Summary.
A Geostationary Operational Environmental Satellite (GOES) Microburst Windspeed Potential Index (MWPI) product image at 0000 UTC June 16, 2008 over western Texas and Oklahoma. Apparent in the product image is a cluster of convective storms that propagated through northwestern Oklahoma between 0000 and 0300 UTC June 16. Downburst wind gusts of 55 and 46 knots were recorded at Camargo and Putnam, Oklahoma Mesonet stations near 0300 UTC. Note that the stronger downburst occurred in close proximity to the highest MWPI value over western Oklahoma (62). Thus, the MWPI product effectively indicated the potential for severe wind gusts of 50 to 64 knots, based on previously derived statistical relationships.

The Rapid Update Cycle (RUC) model Turbulent Kinetic Energy (TKE) three-hour forecast valid1900 UTC July 10, 2008. The TKE image displayed a maximum in index values over the Idaho National Laboratory (INL) complex (near locations “G” and “S” marked in TKE image). Peak wind gusts of 55 knots were recorded in the INL complex between 1905 and 2035 UTC. The TKE product effectively indicated the presence of intense solar heating and strong vertical wind shear in the boundary layer that resulted in turbulent eddy circulations and the strong wind gusts observed over southeastern Idaho.
