Polar Mesospheric Clouds and their Atmospheric Environment

在极地地区有许多卫星 大气中气溶胶粒子密集聚集的观测. 在夏季的几个月里，海拔约为85公里。 这些现象 被命名为极地中层云（PMC）。 这个项目是 继续研究这些问题的起源和性质 云 该项目中包括对该项目的概括- 一个三维的、随时间变化的云物理模型， PMC结构的多维方面。 特别是， 重点将放在季节和纬度结构， 水平风的影响。 气候学将被研究 使用（1977-87）SBUV卫星数据以及新的PMC 数据库*** //

In the polar regions there have been a number of satellite observations of dense collections of aerosol particles at altitudes around 85 km during the summer months. These phenomena have been named polar mesospheric clouds (PMC). This project is a continuation of research into the origin and nature of these clouds. Included in this project is a generalization of the one- dimensional, time-dependent cloud physics model to study the multi-dimensional aspects of the PMC structure. In particular, emphasis will be on the seasonal and latitudinal structure and the impact of horizontal winds. The climatology will be studied using the (1977-87) SBUV satellite data as well as from a new PMC data base. *** //
