闽南沿海地区不同日观测次数大气稳定度的对比

Comparison of atmosphere stabilities for different daily observation times in coastal area of southern Fujian

本文通过地处闽南沿海地区崇武气候站不同日观测次数大气稳定度的对比分析表明 :采用 8个时次和 4个时次观测记录所统计的稳定度频数 ,误差较小(与 2 4个时次比较 ,下同 ) ,对重要结论无大影响 ,能够较准确地描述大气稳定度的状况和特征 ;而采用 3个时次观测资料分析 ,其误差大 ,甚至导致相反的结果 ,实际应用时必须慎重。

In this paper,the atmosphere stabilities for different daily observation times in Chongwu Station of Fujian coastal area are compared.Results show that the stability frequency for 8 and 4 daily observation times has less errors (compared with 24 daily observation times) and no significant influence to important conclusions,that can describe quite accurately the situation and feature of atmosphere stability;While for 3 daily observation times,it has more errors and even causes opposite results.
