  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

    本文用夏季( 6 - 8月)中國東北地區91個測站44年氣溫資料,對該區夏季氣溫的氣候平均和異常場進行分析,採用諧波分析將異常變化的年代際、年際尺度分量分離,分別分析兩種尺度上氣溫異常的時空特徵,最後應用reof進行了氣溫異常的區劃,研究局域異常變化的年代際、年際分量的變化特徵。結果發現: 1 )東北夏季有三個異常高溫高發區和三個異常低溫高發區。全區性異常高溫(低溫)階段出現在上世紀80年代后( 70年代) 。
