Abstract: By means of complex singular value decomposition (CSVD) and according to the monthly mean dataset of sea surface temperature (SST) over the North Pacific,observation of long-wave radiation (OLR),temperature of black body radiation (TBB) and 500 hPa height in the year of 1982～1983,primary study of the relationship between traveling SST fields and general circulation is carried out.Results show:(1) In the year of 1982～1983,the change of SST has a large space scare,but there is still differed of the change of direction and degree between each ocean.Such as,continuous process of heating exists in equator Pacific,and it may be spread to the East.Resource and converge of SST field spreading exist in equator Pacific.(2) In low latitudes area,OLR,TBB field and SST field are closely related.Strengthen of convection is nearly consistent with the change of SST heating.Tropical convection plays an important role in the interaction between ocean and atmosphere.(3) In the amplitude and phase space field of 500 hPa height,both amplitude distribution and phase gradient direction showed the impact by the forward and backward of subtropical high.(4) According to the relationship between ocean and atmosphere showed by the singular value,the relationship between 500 hPa height and SST field is closer than OLR,TBB field and SST field.(5) Calculation shows CSVD was very representative in the study on the relationship between the two traveling field,it also has the ability to diagnose and extract the middle-strong dignal and preferred signal from element field.CSVD method is valued to be spread.
