  1. The results show that : l ) there are three anomalous high temperature areas and three anomalous low temperature areas, and the whole area high temperature anomaly took place in the late 1980s, whereas the low temperature anomaly in the 1970 ; 2 ) the spatial mode manifests identical variations in the whole area, and the temporal coefficient curve is of 2 - 3 year period oscillation and an interdecadal abrupt in the late 1970s ; 3 ) the variance of interdecadal component is obviously larger than that of interannual in the most part of nespa ; 4 ) the interdecadal variation of the temperature is mainly linear ascendance in the late 1970s, the large range anomalous high ( low ) temperature occurs when the interdecadal and interannual anomaly are both positive ( negative ) in the year ; 5 ) the temperature anomaly is divided into four patterns : southern, northern, eastern and western patterns, in which the interdecadal variation of the southern and western patterns is relatively importance and the interannual variation of eastern and northern pattern is relatively importance
