The monthly values of the zonal wind vertical difference or zonal wind shear(ZWS) between 200 hPa and 850 hPa are used to assess the interannual variability of the tropospheric circulation anomalies.

The main purpose is to analyse the interannual variability of climate over China region.

The interannual variability of the summer WPSH hindcasted by the GAMIL CliPAS tier-two experiment is investigated.

In this paper,based on RS,GIS and statistical approaches,the land use amount,change extent,annual change rate,dynamic degree,dominance degree and so on in Hotan River Basin of Xinjiang during the period of 1990-2005 were analyzed.

Decadal variability in the North Pacific as simulated by FGOALS_g fast coupled climate model;

An EOF analysis of the decadal variability of sea temperature anomaly fields at upper-ocean standard levels has been performed in this paper,and the abrupt change feature of sea temperature has been tested by use of movable t-test technique.

is also used to discuss the WDOG effects on decadal variability of THC.

The progress of studies on inter decadal climate variability of the Pacific atmosphere ocean system is reviewed,a brief introduction is given to inter decadal variability of atmospheric circulation, oceanic state and their interaction,as well as main mechanisms of inter decadal variability of the Pacific atmosphere ocean system.
