Mesoscale Studies of Instability Patterns and Winds in the Tropics.
Abstract
The trade-wind inversion and other rapidly drying layers in the lower troposphere over Miami are studied using a diagnostic technique based upon the vertical gradient of atmospheric refractivity. The resulting climatology is presented and discussed. Fluctuations in 10-cm radar video from a diffuse evening angel pattern are analyzed using spectral techniques. The resulting motions suggest that this type of angel provides a convenient tracer for short-period atmospheric waves. A model of summer convection in South Florida as revealed by gridded radar data is described and illustrated. Various correlations are also made between two-dimensional indicies of cloud and echo coverages versus daily rainfall. Our satellite ground station with its unique electronic-expansion display capability is described. Finally, the observation of intersecting radar fine lines and a South Florida tornado provides the small-scale documentation of earlier pressure-jump theories. (Author)
