| 摘 要： | 分析了2008年广东“史上最强龙舟水”的气候成因。结果表明：（1）从2007年8月持续到2008年5月的拉尼娜事件，是强降水的主要气候诱因，在其影响下，西太平洋暖池一带热带对流活跃，有利于不稳定能量向北输送；西太平洋副热带高压偏弱、偏东，雨带滞留华南；南海季风爆发偏早、偏强，为强降水提供了丰沛的水汽条件。（2）去冬今春南极海冰面积偏大和青藏高原南部积雪偏少，有利于增强夏季风环流。

| Abstract: | The climate causation of the strongest dragon-boat precipitation(heavy rainfall around Chinese dragon boat festival) in Guangdong province in 2008 is investigated,and the results show that:(1) The La Nina event which started in August 2007 and ended in May 2008 is the main climate reason for heavy rainfall.Under the influence of La Nina event,the tropical convection was more active,bringing unstable energy towards South China;The western Pacific Subtropical High is weaker and its position is farther eastward than usual,leading to the rainbard's lingering over South China;the South China Sea monsoon set in earlier and stronger than usual,providing abundant water vapor for heavy rainfall.(2)The area of Antarctic sea ice was larger and snow cover over the Tibetan-Plateau was less than usual during winter 2007 to spring 2008,which is favorable for strong Asian summer monsoon circulation. |
