This research is devoted to an observational study of the microphysical, kinematic and electrical structure of warm-based convective clouds in Central Florida as part of the convection and Precipitation/Electrification (CAPE) experiment. Investigations include multiple-Doppler synthesis of winds, polarization radar (CP-2) data, aircraft data, and a variety of in-situ and surface-based electrical measurements. Modeling studies include calculation of propagation/scattering using polarimetric measurements for a variety of hydrometeors. Adding a "radar" module to the CSU Regional Atmospheric Modeling System (RAMS) is proposed based on a new microphysical module currently being developed by Dr. Cotton's group. The latter will focus on identification of the "optimum" mix of polarimetric/dual- frequency radar signatures useful for cloud electrification, hydrometeor classification, and storm evolution studies.

本研究致力于对佛罗里达州中部暖基对流云的微物理、运动学和电学结构进行观测研究，作为对流和降水/带电（CAPE）实验的一部分。 调查包括风的多普勒合成、偏振雷达 (CP-2) 数据、飞机数据以及各种现场和地面电测量。 建模研究包括使用各种水凝物的偏振测量来计算传播/散射。 基于 Cotton 博士小组目前正在开发的新微物理模块，建议在 CSU 区域大气模拟系统 (RAMS) 中添加“雷达”模块。 后者将侧重于确定可用于云带电、水凝物分类和风暴演化研究的极化/双频雷达特征的“最佳”组合。
