福建省大雾分区客观预报方法研究

Research on the Objective Forecasting Ways of Heavy Fog Zoning in Fujian Province

通过统计福建省大雾天气的气候特征以及成雾的气象要素特征,总结出成雾的气象要素指标。基于福建省中尺度数值预报模式产品,利用完全预报(PPI)方法,建立由降水、相对湿度、风向、风速、逆温等因子的预报概率方程,对大雾分区进行了客观预报。

The climatic characteristics of heavy fog weather and meteorological element characteristics of fog formation in Fujian Province were expounded. The meteorological element indices of fog formation were summarized. Based on the meso-scale numerical prediction model, the probability forecast equation that included the elements of rainfall, relative humidity, wind direction, wind velocity and inversion temperature was established by using the method of PPI, so as to forecast heavy fog zoning objectively.
