- 摘要:
- 为了探讨热带MJO对四川地区夏季降水的影响,利用NCEP/NCAR再分析资料、澳大利亚气象局监测的实时MJO指数及中国756个国家气象站逐日降水资料,分析2000～2010年夏季MJO(Madden-Julian Oscillation)与四川降水的对应关系,结果表明,MJO位于不同位相时对四川降水的影响不同,且强弱MJO事件在相同位相对四川降水的影响也不同:当MJO位于第1、4、7、8位相时,四川地区夏季降水主要分布在西南部及东部局部地区,当MJO活动中心位于第2、3、5位相时,四川降水主要分布在东北部; 当MJO位于第1、2、6位相时,四川单站降水距平百分率为正,位于其他位相时为负。强弱MJO事件对四川降水的影响差异主要在第6、7位相; 当强MJO对流活动中心位于第2位相时,四川降水正距平百分率分布范围最广,降水距平百分率最高可达75%以上,位于第7位相时,四川单站降水距平百分率为负。而当弱MJO活动中心位于第6、7位相时,正降水距平百分率在四川分布最广,单站日平均降水距平百分率分别达31.22%和15.64%。
- Abstract:
- In order to study the influence of MJO(Madden-Julian Oscillation)on Sichuan precipitation, the paper used NCEP/NCAR data, RMM index provided by Australian Bureau and daily precipitation data of 756 stations over China analyze the relationship between MJO and summer precipitation during 2000-2010.The precipitation is different at MJO phases and the precipitation of strong MJO differs from weak MJOs':The precipitation was distributed at southwestern and some areas in eastern when MJO was movable at phase 1,phase 4 and phase 7-8,while at northeast when MJO was movable at phase 2-3 and phase 5.The negative precipitation anomaly of Single Station occurred phase 3-5 and 7-8,while positive at phase 1,phase 2 and phase 6.The different influence of strong/weak MJO at Sichuan precipitation occurred phase 6 and phase 7:The largest scale of positive precipitation anomaly distribution was at phase 2 of strong MJO with highest precipitation anomaly percentage 75% while negative at phase 7.The largest scale of positive precipitation anomaly distribution was at phase 6-7 of weak MJO with the precipitation anomaly of Single Station was 31.22% and 15.64%.
