| 摘 要： | 本文以大量资料为依据,重点分析了低纬度沿海地区的主要气流类型,海陆风特征和冬、夏季风条件下边界层盛行风向及平均风速随高度分布特点。从大气扩散角度出发,将边界层风向、风速垂直分布分别分成4种类型和5种类型,并给出各种类型的出现频率。最后,结合湍流特征,分析了不同流场对大气扩散的影响。

| Abstract: | Based on a great quantity of data, this paper mainly analyses the major flow patterns, the characteristics of sea-land breeze and the feature of vertical distribution of prevailing wind direction and average wind speed in case of winter monsoon and summer monsoon in the low latitude, in view of atmospheric diffusion, the vertical distribution of the wind direction and the wind speed within the boundary are divided into 4 and 5 categories separately, of which the frequency is given. Finally, the influence of various flows on the atmospheric diffusion is analyzed in combination with the characteristics of the turbulence. |
