【Abstract】 This paper analyses the statistical method of wind direction and the simulation model of wind factors systematically,and also points out the rational aspect of various handling methods(modelling)and the existing problems.Also,this paper suggests an improved statistical method of wind vector(including average value of wind direction,standard errors, deviation coefficient ,self-related coefficient and the calculation method of wind speed interaction coefficients).In addition,the model of 4-stage and self-returning wind field is modifized.更多还原
