Distribution Characters of Fog in Chongqing and Causes of Fog in November 7, 2006

Abstract:

The paper use the observational data of Chongqing from 1981to 2010, to analyze the spatial and the temporal distribution characters. The results are the follows: (1) Chongqing has two Foggy areas, one is the north by central region with Changshou, Fuling as the center, the other is the northwest region with Hechuan, Beibei as the center. (2) The fog mainly occurs in winter, and especially often occurs in December. (3)The number of the fog days are reduces in most Chongqing areas from 1990s to 2000s. Based on the NCEP reanalysis data, the paper analyze a fog weather, the results indicate that the wind by north at 500 hpa, the anticyclonic circulation at 700 hpa, the precipitation a few days ago, the high humidity at the lower layers and low humidity at higher layers cause the fog in November 7, 2006.
