摘要
根据广东沿海地区大气边界层测试资料和气象台站连续5a的常规观测资料,分析广东沿海地区边界层风场的基本特征.结果表明:广东沿海地区盛行偏东风,平均风速较大,但静风频率也较高.四季都有海陆风,以珠江口地区出现频率最高.各地近地层盛行风向不同,500m以上高度盛行风向差异较小.夏季风速随高度增加而增加,冬季随高度呈双峰型分布.大气稳定度以中性D类为主,地区差异较明显,珠江口附近不稳定类稳定度最小.
Based on lots of the boundary layer observed data and weather station's data for five successive years (1986~1990) over coastal land of Guangdong, some characteristics and variation of wind field in the boundary layer over the region are analyzed. The results reveal that compared with the wind field over the inland area, the mean wind speed is large, and that vertical wind profile which agrees with power law only appears in the layer near the surface. The sealand breeze is very active all the year round with seasonal differences. The stability varies obviously.
