| 摘 要： | 应用实测资料、NCEP／NCAR再分析资料对2007年2月8—13日石河子地区出现的大雾天气进行诊断分析。结果显示：地面高压、高空暖脊与大雾的形成与消散有着直接的关系；逆温层的存在是大雾出现的必要条件；与大气层结稳定度有关的物理量对大雾天气也有一定的指示意义。

| Abstract: | Using the measured data and NCEP/ NCAR reanalysis data,we studied the heavy fog event occurred in Shihezi area from 8th to 13th Feb., 2007. The results show that the ground high and the warm ridge in high level are directly related to the formation and dissipation of heavy fog, the inversion layer is a necessary condition for the emergence of heavy fog, and the physical variables related to atmospheric stratification stability are indicative to heavy fog. |

| Keywords: | heavy fog inversion layer stability |
