摘要
Atmospheric and oceanic data collected by 'Shiyan 3' and 'Kexue 1' during the IOP in SCSMEX 98 (Ding et al.2002) were used to calculate the air-sea turbulent flux exchange.Here the calculation was based on the bulk aerodynamic formulas,which had considered the influence of wind speed and atmospheric stratification.Some characteristics of air-sea exchange were analyzed by examining the results.We found that the onset of the summer monsoon began in the southern region of the South China Sea on May 21 and extended northward to the whole SCS region.There were obvious differences in the characteristics of atmosphere and sea structure,air-sea turbulent flux exchange between south and north.Moreover,the variation of SST is mainly related to the latent flux transfer besides global radiation.We also gave an explanation for the later onset and weakness of the summer monsoon,and a comparison with westerly wind burst in the western tropical Pacific Ocean from 1992 to 1993.
