Abrupt Climate Change in Ulanbuh Desert in the Nearly 60 Years

Abstract:

Ulanbuh Desert located in the ecological environment fragile areas of the monsoon margin, which is extremely sensitive to climate change. With the support of the temperature and precipitation data of the four meteorological stations in the distribution of Ulanbuh Desert margin over the nearly 60 years data, and by using the Mann-Kendall and the Mann-Whitney test, the mutation changes has analyzed. The results show that the temperature of the study area after its significant change in 1990 has been through a obvious warming process, and the average temperature from 1990 to 2010 was more than 1 °C higher than in 1955-1989. While there was a slight increase trend in the precipitation after its significant change in 1992, and the climate condition is generally warm and dry, so temporarily the conclusion that the climate condition will change to warm and wet is impossible.
