外热带大气扰动对ENSO的影响
ENSO 外热带大气扰动 西风异常 经向风异常
2008/5/25
合成分析了20世纪80年代以来5次主要的ENSO事件,发现外热带大气扰动通过经向风异常不仅对ENSO的发生起到重要的触发作用,而且影响到ENSO的发展和衰减. 因此,尽管ENSO对外热带大气扰动有影响,但同时外热带大气扰动又与ENSO有相互作用. 在ENSO发生前,南印度洋中纬度为反气旋异常,并通过Rossby波的频散作用加强了澳大利亚附近的反气旋异常;同时,澳大利亚东部沿海的南风异常与菲律宾附近...
Abstract近几年的一系列分析研究表明,ENSO与异常东亚冬季风之间有相互影响,持续的强(弱)东亚冬季风通过引起赤道西太平洋地区的西(东)风异常对ElNio/LaNia的发生起着重要作用;赤道太平洋次表层海温异常(SOTA)的年际变化(循环)与ENSO发生有密切关系;ENSO的真正源在西太平洋暖池,暖池正(负)SOTA沿赤道温跃层东传到东太平洋,便导致ElNio/LaNia的爆发;在暖...
选取1979年以来6次主要ENSO事件, 并按其强度划分为强和中等强度, 合成分析了ENSO对东亚夏季风和中国东部夏季降水的影响, 发现ENSO的影响随夏季季节进程有明显变化, 6月影响较弱而8月影响最强, 这显示ENSO的影响有很长的滞后效应. 此外, 强ENSO造成的环流和降水异常强度大, 影响开始的时间也较早, 而中等强度ENSO的影响在8月才较为明显. 同时, 中等强度ENSO年的合成结果...

2010/1/25
Precipitation anomalies caused by the warm phase (El Niño) of the ENSO cycle lead to a strong decrease of water resources in South-East Asia. The aim of this work is to study the impact of warm...
