| Abstract: | An analysis is made of a frontal fog event occurred in the low-latitude mountainous area in Guizhou Province between 21 and 22 February 2008 by using conventional observation and NCEP/NCAR reanalysis data.The results show that the frontal fog occurred under special weather.The key weather systems for frontal fog formation include: the strong southwest air current at 500 hPa,the low-level southwest jet,and the decreasing quasi-stationary front.The fog lasted from evening to next morning,and the large area of... |
