A powerful influence on the weather that we experience on the ground can be exerted by the
stratosphere. This highly stratified layer of Earth's atmosphere is found 10 to 50 kilometres …

We review teleconnections within the atmosphere and ocean, their dynamics and their role
in coupled climate variability. We concentrate on teleconnections in the latitudinal direction …

The coupling between the stratosphere and the troposphere following two major
stratospheric sudden warmings is studied in the Canadian Middle Atmosphere Model using …

Teleconnections between the Quasi Biennial Oscillation (QBO) and the Northern
Hemisphere zonally averaged zonal winds, mean sea level pressure (mslp) and tropical …

Extreme variability of the winter‐and spring‐time stratospheric polar vortex has been shown
to affect extratropical tropospheric weather. Therefore, reducing stratospheric forecast error …

The stratospheric polar vortex can influence the tropospheric circulation and thereby winter
weather in the mid-latitudes. Weak vortex states, often associated with sudden stratospheric …

Large-scale, intra-seasonal to inter-annual variability of the stratosphere is reviewed. Much
of the variability is dynamical and induced by waves emanating from the troposphere. It is …

Reanalysis data are used to evaluate the evolution of polar vortex geometry, planetary wave
drag, and gravity wave drag prior to split versus displacement sudden stratospheric …

The atmospheric response to the solar cycle has been previously investigated with the Freie
Universität Berlin Climate Middle Atmosphere Model (FUB‐CMAM) using prescribed …

摘要利用NCEP/NCAR 再分析资料和我国160 站月平均气温资料, 首先采用线性回归的方法
分析了从1958 至1998 年40 个冬季北极涛动(AO) 与东亚气候异常的关系. 结果表明, 当AO …
