| 摘 要： | 利用广东新会崖门夏、冬季大气边界层综合测试资料，分析珠江崖门出海口地区的大气边界层特征。研究表明：边界层内６００ｍ左右是一个特征量的转折点，风速廓线明显偏离幂指数规律，平衡球法得到的扩散参数和Ｒａｓｑｕｉｌｌ－Ｇｉｆｆｏｒｄ曲线符合良好，三向风速仪法得到Ｄ，Ｅ，Ｆ类稳定度的扩散参数为Ｐａｓｑｕｉｌｌ－Ｇｉｆｆｏｒｄ曲线的２—３倍。珠江崖门出海口地区大气边界层特征和内陆地区有一定差别。

| Abstract: | ased on an observational experiment carried out in Yamen,Xinhui,Guangdong,an estuary area of Zhujiang Riyer,some characteristics of the atmospheric boundary layer are investigated.The analysis reveals that around 600 m in the boundary layer there is a characteristic turning point.The wind profiles in the estuary area do not agree with pewer law, but the diffusion parameters obtained by equilibrium balloon agree well with Pasquill-Gifford diffusion parameters, and stability of D, E, F class diffusion parameters obtained by three-axes propeller anemometers is 2 or 3 times that of Pasquill-Gifford diffusion parameters. There is some difference between the characteristics of atmospheric boundary layer in the estuary area and inland area. |
