| Abstract: |
| Based on the climatic data in 1953—2007 of meteorological stations over Shihezi, the changing trend of climate factors and its abrupt changes were analyzed. The results showed that the temperature increased after the mid-1980s and climatic warming has accelerated since the 1990s due to the rise of temperature in spring and winter. The precipitation experienced a changing trend, from lower (the 1970s) to higher (after 1980s)．Affected by the pre
cipitation, the aridity index went through a “humid-dry-humid” progress. Climate break analyzing denoted that the abrupt change of temperature was obvious as precipitation in the study area. The abrupt changes of temperature accumulated
in 1980s and 1990s. However, the abrupt changes of precipitation were not so consistent, they were disturbed in 1960s, 1970s and 1980s. The aridity index underwent a dryer and wetter abrupt change in 1960s and 1970s. |
