Abstract

In this paper, the observed meteorological data of 54 meteorological stations from 1960 to 2009 in Jiangsu Province of China were collected and a composite index (CI) of meteorological drought was used to analyze the temporal and spatial characteristics of droughts in the province. Based on the daily CI values of each station in the 50 years, the drought processes of each station were confirmed one by one and the occurrence frequencies, scopes and severities of the meteorological droughts were computed and analyzed to reveal the temporal and spatial occurrence pattern of the meteorological droughts in different parts of Jiangsu Province. The results were showed as follows. (1) The annual and seasonal occurrence frequencies of the meteorological drought in the province decreased from north to south. In all the seasons, the occurrence frequency of the winter droughts was the highest. (2) The years of drought occurrence in a large scope (more than 90% of the total area of the province) were most in winter and least in summer. (3) In the 50 years, there was a notable inter-annual wave of the annual average lasting days and the annual average occurrence severities of meteorological droughts in the whole province but their linear changing tendencies were not obvious. (4) The drought lasting days of different grades in Jiangsu reduced from north to south in general. The drought lasting days of different grades were most in winter and least in summer.

Key words： Jiangsu; meteorological drought; composite index; GIS; temporal and spatial pattern
