Abstract: The distribution of negative correlation center in the North Pacific Ocean from the low level to high level and characteristics of other anomalous centers which have strong correlations with the North Pacific Ocean are analyzed using the NCEP/NCAR global height field data and surface pressure data. Research results show that the distributions of the centers which have remarkable correlations with the North Pacific Ocean are always the same in each height field, and the three correlation centers are: negative centers in the central equatorial Pacific and the Bering Strait, positive center in the southeast of the North America continent. The correlations between grid points in the North Pacific Ocean and grid points in these three centers show that there is an obvious negative correlation center in the North Pacific Ocean at each height which reflects a character of barotropic structure, and the negative center moves eastward with the height increasing in the meridional direction while the ambulation in the zonal one is irregular; in these anomalous centers, the most remarkable center at 700 hPa、 500 hPa, and 200 hPa which influences the the North Pacific Ocean is the negative center in the central equatorial Pacific while that in the surface pressure field is the negative center in the Bering Strait. The correlation center first influencing the North Pacific Ocean is the positive one in the southeast of the North America continent for surface pressure and 700 hPa, and is the negative one in the central equatorial Pacific at 500 hPa and 200 hPa.
