Based on the continuous observation data at the 90 meteorological sites in Xinjiang,a self-calibrating Palmer drought severity index(PDSI) is firstly used to investigate the annual and seasonal variation of drought and wet conditions in the region during 1961-2003.
利用新疆气象局提供的90个气象台站的连续观测记录,计算了1961~2003年新疆地区年平均和季节平均自适应Palmer干旱指数的气候态及其变化趋势,表明新疆地区气候就平均态而言整体上属于正常的气候条件,研究时段内年平均和季节平均气候以湿润化趋势为主要变化特征,定性的分析显示地表气温的持续上升倾向于引起干旱化,而降水的增加则有利于气候的湿润化趋势。
