摘要2000年5月至7月，在科罗拉多州和堪萨斯州边界附近的高平原进行了强雷暴电气化和降水研究（STEPS）。STEPS旨在更好地了解严重雷暴中运动学、降水和电气化之间的相互作用。具体的科学目标包括：1）了解超级单体降水量的明显主要差异，这些差异导致超级单体被分为低降水量（LP）、典型或中等降水量和高降水量; 2）了解风暴中闪电的形成和行为，以及闪电在风暴类型之间有何不同，特别是更好地了解风暴产生主要是积极的云对地（CG）闪电的机制; 3）验证和改进偏振雷达的微物理解释。该项目涉及使用多多普勒极化雷达网络，以及到达时间甚高频（VHF）激光雷达。
Abstract During May–July 2000, the Severe Thunderstorm Electrification and Precipitation Study (STEPS) occurred in the High Plains, near the Colorado–Kansas border. STEPS aimed to achieve a better understanding of the interactions between kinematics, precipitation, and electrification in severe thunderstorms. Specific scientific objectives included 1) understanding the apparent major differences in precipitation output from super-cells that have led to them being classified as low precipitation (LP), classic or medium precipitation, and high precipitation; 2) understanding lightning formation and behavior in storms, and how lightning differs among storm types, particularly to better understand the mechanisms by which storms produce predominantly positive cloud-to-ground (CG) lightning; and 3) verifying and improving microphysical interpretations from polarimetric radar. The project involved the use of a multiple-Doppler polarimetric radar network, as well as a time-of-arrival very high frequency (VHF) lig...
