Relationship between the Climate Change and Dust Storm Occurrence in China
نویسندگان
چکیده
Monthly mean air temperature and precipitation data, monthly dust storm frequencies (times of dust storm occurrences) of 107 stations in North China were analyzed to clarify the relationship between the climate change and dust storm occurrence. Arid regions of North China were divided into five and trends of dust storm occurrence and climate changes showed different patterns for these regions, although a decreasing trend of total dust storm occurrence and an increasing trend of temperature for whole North China. Dust storm occurrence decreased clearly and had a good relationship with temperature increasing in spring and precipitation increasing in winter in Northwest China, while that in Northeast China showed an increasing trend in recent years and had no clear relation with temperature and precipitation change. Keyword: Climate change, Dust storm, Regional division, Temperature increase
