| 摘 要： | 选取萍乡和莲花2个站点1980—2003年722个雾日样本,按年、季、月对雾日的变化进行了分析,探讨了辐射雾、平流雾形成的主要气象因子和天气形势。通过普查气象因子和相关性回归分析,筛选出与雾日相关性比较好的6个气象因子,分别建立春、秋、冬三个季节雾的能见度预报方程,并进行了验证和实际应用。预报方程春季预报准确率最高,冬季次之,秋季相对较低。

| Abstract: | The annual,seasonal and monthly variations of 722 fog samples from 1980 to 2003 of Pingxiang and Lianhua stations are analyzed and the main meteorological elements and synoptic situation for radiation and advection fogs were discussed.By general investigation of meteorological elements and correlation regression analysis,six meteorological elements having better correlation with fog are selected to establish fog prediction equations for spring,autumn and winter,which are tested and applied in practice.It is indicated that the fog prediction equation has the highest forecast accuracy in spring,the second in winter and relatively low accuracy in autumn. |
