[Objective]The study aimed to analyze climatic characteristics and vulnerability of fog in Changzhou. [Method]Based on the data of fog from 2006 to 2012 observed at Longhutang observation station and disaster condition in Changzhou in recent years,fog distribution and vulnerability of Changzhou were analyzed. [Result]Most fog happened from November to February in 2006 and 2007,while less fog happened in 2010,and fog seldom occurred in summer. Average monthly fog days were from 0. 3 to 4. 0,and the maximum appeared in November. The average visibility was 382 m. Generally,the fog with long duration appeared in autumn and winter. The average duration of fog in 2010 was the shortest among these years,about 3 h,while the longest duration of fog was in 2008,up to 7 h. Fog mainly caused damage to traffic systems,human health and economy. Population density,GDP per capita,civil aviation landing flights and highway mileage density were selected to evaluate fog disaster vulnerability,and the results showed that Changzhou was the most vulnerable,followed by Jintan,then Liyang. [Conclusion]The research could provide scientific references for the reduction of losses caused by fog.
