Title: The effects of the interdecadal variations of atmospheric circulation on SAT anomaly of the North-East Asian in winter
Abstract: The NCEP/NCAR reanalyzed surface atmospheric data (SAT) are used to analyze the temperature variations in winter from 1949 to 1999.The dominant spatial and temporal patterns of SAT in Asia are studied by empirical orthogonal function (EOF) analysis.The results demonstrate that SAT of EAN has increased since the 1970's,and has vary clear interdecadal changeable feature.This kind of anomalous atmospheric temperature variability is mainly influenced by the winter monsoon.During the recent two decades,AO always stays at high phase and increases continuously,at the same time the winter monsoon is decreasing.The singular value decomposition (SVD) analysis for the SLP field and the SAT field is carried out The results shows that AO possibly effects the warming in EAN.
