AB: The Cirrus Regional Study of Tropical Anvils and Cirrus Layers - Florida Area Cirrus Experiment (CRYSTAL-FACE) field campaign provided a unique opportunity to study convective characteristics in South Florida. CRYSTAL FACE took place during July 2002. Four Weather Surveillance Radar - 1988 Doppler (WSR-88D) radars along with the NASA polarimetric (NPOL) 10 cm radar data were available during CRYSTAL FACE. The experiment provided a unique opportunity to study the evolution of convection and determine source regions of cirrus anvils in South Florida. The four WSR-88D and NPOL radar data were merged to provide a composite dataset of the radar echoes observed in South Florida. Radar echoes were tracked with time using cross correlation technique by determining the Lagrangian Autocorrelation between sequential radar observations. This analysis provides information about the mean wind fields and the initial source regions of the convection generating the cirrus anvils. A spectral decomposition of storm scales was applied to the dataset in efforts to gain a better understanding of the evolution of the convective systems at various storm scales. An overview of this study along with preliminary results will be presented in the poster.
