Abstract : A reliable method is presented for the prediction of convective precipitation in south Florida. Total area diverence is statistically related to area rainfall as derived by radar in a mesoscale region on the order of 1400 sq km. Various network grids and sizes are examined to find the best scale to measure total area divergence. The response of visible clouds to surface convergence is investigated with time-lapse photographs taken in the FACE mesonetwork. One case study of a convective storm complex as measured by Doppler radar and surface pressure data is presented. Finally, vertical adjustment factors are determined for surface winds under varying meteorological conditions and time of day. (Author)
