雾微物理结构的观测分析

本文简述了用光电法观测雾微物理结构的工作特点及资料处理中的有关问题。根据观测结果对雾滴浓度、雾滴谱及雾中含水量等参数及其演变特征做了粗略分析。结果表明,雾滴谱分布是雾体演变的主要表征量,而单位体积中大雾滴数量的增加,小滴数量的比例相应减小,雾滴谱加宽则是雾体发展的主要特点。

AN ANALYSIS OF THE MICROPHYSICAL STRUCTURE OF FOG

The note for the observations of the microphysical structure of fog by optical-electrical method and some problems about the data processing are described in the Paper.Analysis of microphysical properties of fog,such as the drop concentration,the size distribution of the fog drops and the water content in the fog,is given.The result shows that distribution of drop spectrum is the most important characteristic factor in the fog evolution process.Basic characters for fog development are: 1)the number of larger drops increases,2)the fraction of smaller drops decreases and 3)the drop size distribution widens.
