摘要
基于南海气象站的气象资料,首先对三种极值分布的参数进行估计,并对三种极值分布进行线性相关性检验,得出南海气象站风速极值分布更接近Weibull分布;其次对Weibull分布参数的谐波函数拟合曲线,得到任意风向角下的分布参数;最后分析各风向角下的基本风速;所得到的结果可为建筑结构抗风设计提供参考。
This article is based on meteorological data from Nanhai weather stations.Firstly,three kinds of extreme value distributions parameters are estimated and the linear correlation test is conducted.The result shows extreme value distribution of wind speed of the weather stations is closer to the Weibull distribution.Secondly,the Weibull distribution parameters of arbitrary direction are fitted by using harmonic function.Finally,the basic wind speeds in some wind angles are analysed.The results of the paper are useful for wind-resistant design of buildings.
