北半跨冬半年大西洋地区海气相互作用及其遥相关

ATMOSPHERE AND OCEAN INTERACTION AND TELECONNECTION IN THE ATLANTIC IN THE NORTHERN WINTER

摘要: 本文分析表明,冬半年大西洋海温场及其海气的相关场都具有明显的WA型遥相关结构,且主要是海温相对较高频率变化的贡献。海气系统的这种遥相关结构是互相维持的,它们具有准一年的振荡周期。WA型的振荡变化对中高纬以及热带地区的环流和大气有着重要的影响。

Abstract: The SST pattern and its link to the atmosphere in the Atlantic are the distinct teleconnection WA in winter half year, It is evident that the relatively higher frequencies account for most of the WA signal.The linked pair of atmosphere and ocean patterns might be mutually supportive and have a quasi-annual cycle.
