Investigation of Cloud Microphysical, Kinematic and Electrical Characteristics

该项目的总体目标是加强对降水和电气化发展的了解，以及在温暖的云中，“暖雨”过程，包括聚结-冻结，是活跃的。这项工作包括利用装甲T-28气象研究飞机收集的数据，结合其他飞机、雷达和其他观测系统收集的数据，研究云的微物理、运动学和电气特性。T-28将探测成熟对流风暴的内部，以获得有关风、亚云尺度动力结构、温度、微物理特性和电场结构的现场信息。T-28进行的电场测量将与地面场和闪电位置测量，以及其他飞机和垂直电测深的测量相结合，以帮助推断风暴中的电荷分布，其随时间的演变，以及它如何受到微物理和动态电荷分离机制的影响。

The general objective of this project is to enhance understanding of the development of precipitation and electrification, as well as the association between the two, in warm-based clouds where "warm rain" processes, including coalescence-freezing, are active. The work involves study of the cloud microphysical, kinematic, and electrical characteristics using data collected with the armored T-28 meteorological research aircraft, in conjunction with data gathered by other aircraft, radars, and additional observing systems. The T-28 will probe the interiors of mature convective storms to obtain in situ information on winds, sub-cloud-scale dynamical structures, temperatures, microphysical properties, and the electric field structure. Electric field measurements made by the T-28 will be combined with surface field and lightning location measurements, as well as measurements from other aircraft and vertical electrical soundings, to help deduce the charge distribution in the storms, its evolution with time, and how it may be influenced by microphysical and dynamical charge separation mechanisms.
