格尔木地面、低空风场特征分析

利用格尔木地面和探空风速、风向资料,对格尔木风场特征进行分析。得出各季平均风速的日变化较为明显;年内各月之间平均风速变幅不大;大气边界层风速随高度增加而增大;低空风速的垂直变化一日中只有07时平均风速基本上随高度增加而稍有增大。格尔木常年以西风为主导风向,其次是西西北风和南西南风,各风向下的平均风速玫瑰图春、夏、秋、冬及年很相似,均以偏西风最大,偏东风次之。格尔木常年以w为主导风向,其次是wws风和sws。日变化中10～17时为一日中较大时段,20～23时为一日中较小时段。小于1.5m/s和1.5～3.0m/s的风速频率高,风速较大有利污染物的扩散。

Surface and low altitude wind field characteristics in Golmud city

Using the Golmud ground and the meteorological sounding wind speed and the wind direction data to analyze the wind field characteristics. The diurnalvariation of seasonal wind velocity is obvious; the wind velocity amplitude is not big among each month; The atmospheric boundary layer wind speed increases along with the hight increasing; The westerly wind is as the leading wind direction,next is the cubic centimeter north wind and south the southwest wind,under various wind directions average wind velocity r...
