摘要
利用贵阳市1971～1990年春、夏、秋、冬四季代表月（1，4，7，10月）风速自记记录资料，统计了月各级静风持续时间及其出现频率，并用Weibull分布函数对各季代表月的静风持续时间资料分别进行拟合，导出了各自的分布函数．结果表明：贵阳市实际静风持续时间百分率仅为8．48％～10．89％比常规气象资料统计的静风频率23％～30％小1－2倍：贵阳市地面以上0～30m的静风持续时间、最长静风持续时间均随高度明显减少：静风持续时间及频率分布没有明显的季节差异．
ttis Paper analyses the boy of season calIn and itS duraion by using the data obSerVed from the year of 1971~ 1990 in Guiyang. The results show that most of the frequency of calm duration are within 1.0 h. The percentages of season calm duration is smaller than the perentagrs of calm. The season calm duration and the maximum season calm duration are decrease with its height increase.According to Weibull's, the season calm duration's distribution functions is obtained, which shows that there are no apparent differene among all the distributions. The simulated results are satisfactry.
