By using the sea level pressure data from NCEP-NCAR reanalysis and monthly mean temperature data from 107 stations in China,the relationships between interannual variations of the Australian high and summer temperature in China have been studied using the SVD singular value decomposition and regression methods.The time series of coefficient of left singular vector of SVD1 was found to be highly correlated with the Australian high index as reported in many studies.The correlation coefficient is 0.97,which sh...
