Nowcasting Convective Storm Evolution in East-Central Florida Using Satellite and Doppler Radar Data

Abstract

The relationship between infrared cloud top temperatures from the Geostationary Operational Environmental Satellite's (GOES) Visible and Infrared Spin Scan Radiometer (VISSR) and radar reflectivity returns from NCAR's CP-4 C- band Doppler radar is examined for nine thunderstorm cells over east central Florida. The cell data are from three case study days during the summer 1991 Convective and Precipitation/Electrification (CaPE) Experiment. Rapid scan satellite data available during the selected case study days provide a high frequency of image times (delta t = 5-15 min.) for better temporal resolution in the data comparisons. A method was developed to graphically combine GOES visible and infrared images with universal format Doppler radar reflectivity and velocity scans for display on a PC workstation. Previous studies by others, my personal forecasting experience, and the present study illustrate a need to combine meteorological data sources in order to improve operational nowcasting capabilities.
