| 摘 要： | 四川盆地 2 0 0 2年汛期 (6～ 8月 )期间 ,高温干旱显著 ,发生时段较常年明显偏早 ,位置偏北。通过对副热带系统、大陆高压、南亚高压等夏季主要环流系统进行分析得出 ,2 0 0 2年汛期期间四川盆地的高温干旱天气主要是由稳定维持的大陆高压所造成。而同期的副热带系统均较常年偏弱 ,不是造成四川省干旱的直接影响系统。此外 ,2 0 0 2年台风活动的间接影响不可忽视。

| Abstract: | The drought from June to August of 2002 over Sichuan Basin was characterized with longer duration, higher temperature, earlier and farther northern location. Based on the analysis of the general circulation, sub-tropical system, Continental High, and South Asian high, it is concluded that the formation of the drought in 2002 over the Sichuan Basin was mainly caused by the Continental High which maintained for a long time, while the sub-tropical weather system was weaker than that in normal years. Furthermore, the indirect impacts of typhoons in 2002 on the drought cannot be neglected. |
