Professor Williams, collaborating with Professor Rutledge of the Colorado State University, will participate in a thunderstorm experiment near Darwin, Australia between November 1988 and February 1989. This award will allow the two principal investigators to operate the MIT 5 cm radar and a network of 10 coronal point stations in the field. The joint operation of the MIT radar and the NOAA TOGA (Tropical Ocean and Global Atmosphere) 5 cm radar will provide, for the first time, dual-Doppler observations in the tropics. The primary objective of Professors Williams and Rutledge's research is to better understand the dynamics and electrification of deep tropical convection and mesoscale weather systems and compare it with what we know of in the middle latitudes. Since the field phase corresponds to the winter monsoon period in northern Australia, this work will also allow a comparison of the behavior of lightning between oceanic storms, prominent during monsoon onset, and continental storms, prominent during monsoon breaks.

威廉姆斯教授与科罗拉多州立大学的拉特利奇教授合作，将于1988年11月至1989年2月期间参加澳大利亚达尔文附近的一次雷暴实验。这项合同将允许两名首席调查人员操作麻省理工学院的5厘米雷达和实地的10个日冕点站网络。麻省理工学院雷达和美国国家海洋和大气局TOGA(热带海洋和全球大气)5厘米雷达的联合作业将首次在热带地区提供双多普勒观测。威廉姆斯和拉特利奇教授的研究的主要目标是更好地了解深热带对流和中尺度天气系统的动力和电化，并将其与我们所知的中纬度地区进行比较。由于现场阶段对应于澳大利亚北部的冬季季风期，这项工作还将使人们能够比较在季风爆发期间突出的海洋风暴和在季风爆发期间突出的大陆风暴之间的闪电行为。
