Impacts of Previous Winter Kuroshio SSTA on Summer Rainfall in China
The relationship of Kuroshio sea surface temperature anomaly (SSTA) in the previous winter and summer rainfall in China was analyzed based on observational studies and numerical simulations. Observational results indicate that there is a close relation between Kuroshio SSTA and precipitation in China. When Kuroshio SSTA is positive, the western Pacific subtropical high will be stronger and extend farther westward in the following summer, with Asian summer monsoon weaker and the frontal precipitation further southward. As a result, summer precipitation increases (decreases) in the mid-lower reaches of the Yangtze River (in North and Northeast China), and vice versa. Conclusions drawn by NCAR-CCM3 testify the observational results.
