Abstract

Abstract

The NOAA OLR data and NCEP/NCAR reanalysis wind data at 850 hPa from 1979 to 1996 were used to analyze the characteristics of low-frequency oscillations (LFO) over the South China Sea (SCS) during the summer monsoon onset. It was demonstrated that the LFO over SCS was active in summer and had obvious interannual variability that was related with the monsoon onset over SCS. The LFO over SCS intensified after the monsoon onset. From 18 a composite analysis of and K^*, we found that the monsoon onset over SCS was closely related with the eastward LFO propagation over the Indian Ocean and westward LFO propagation over the pacific Ocean, and the LFOs over Indian Ocean and Pacific Ocean were linked together in SCS region during the monsoon onset over SCS.
