Microburst Risk Algorithm observes Favorable Conditions for Strong Convective Winds over the Chesapeake Bay

Ken Pryor (NESDIS / STAR) A GOES sounder-derived Microburst Windspeed Potential (MWP) algorithm, based on convective available potential energy (CAPE), and vertical temperature and humidity lapse rates, and based on the vertical difference in equivalent potential temperature (theta-e difference, TED) between the surface and middle-troposphere (between 10,000 and 20,000 feet above ground level) recently observed Continue Reading
