| Abstract: | The interannual variability of the monthly mean temperature in winter of Gansu is studied by a rotated principal component analysis.Three fundamental spatial patterns are obtained,which represent interannual temperature anomalies in winter,the time evolution rule of the corresponding rotated pricipal components reveals various changing trend. |
