| 摘 要： | 根据国家海洋局"908"专项北黄海海区海洋气象观测资料,计算了2007～2008年间该海区4个不同季节的大气湍流强度并与其他海区及陆地下垫面大气湍流值相比较.北黄海海区大气湍流强度量级为10-2,比陆地下垫面大气湍流强度低一个量级.由于海洋的特殊性质,对秋季大气湍流强度日变化的分析发现,在大气湍流强度的影响因素中,海洋的热力作用相对较大.对水平方向风速标准差是否满足Monin-Obukhov相似关系进行了探讨,数据显示,在不稳定层结下冬季水平方向无量纲风速标准差与Z/L的关系,基本满足1/3次方律.秋冬在不稳定层结下垂直方向风速标准差满足Monin-Obukhov相似理论.

| Abstract: | According to the observations over the North Yellow Sea by the project "908" of state Oceanic Administration state Oceanic the turbulence intensity of Atmosphere is calculated.This paper compares these results with these from other sea areas and about land type.Results show the magnitude of turbulence intensity is about 10-2,which is lower than that of the land underlaying surface.Due to the special properties of the ocean,it is found that thermal effect contributes much more to the turbulence intensity bas... |
