A significant advance in the onset dates of the South China Sea summer monsoon (SCSSM) is detected around 1993/94: the epochal mean onset date is 30 May for 1979–93 and 14 May for 1994–2008. The relatively late onset during the first epoch is primarily determined by the northward seasonal march of the intertropical convergence zone, whereas the advanced onset during the second epoch is affected by the enhanced activity of northwestward-moving tropical disturbances from the equatorial western Pacific. During 1994–2008, the intraseasonal variability (ISV) over the western Pacific was enhanced during the period from mid-April to mid-May; further, the number of tropical cyclones (TCs), which passed through the South China Sea (SCS) and Philippine Sea during the same period, is about doubled compared with those occurring during 1979–93. This enhanced ISV and TC activity over the SCS and Philippine Sea are attributed to a significant increase in SST over the equatorial western Pacific from the 1980s to 2000s. Therefore, the advanced SCSSM onset is rooted in the decadal change of the SST over the equatorial western Pacific.

Since 1945 the South China Sea and the western Pacific has functioned as an uncontested global common patrolled by overwhelming U.S. naval and air power projected from a series of peripheral and over the horizon bases. The dramatic rise of China alters this situation and has transformed the South China Sea into a frontier of control as China seeks to morph this maritime theater into a landward extension of the Chinese coast where it can deploy land-based tactics into an arena previously dominated by maritime power and tactics to secure the South China Sea as a de facto territorial water that serves multiple Chinese strategic interests. Hence, the attempt by a land-based Eurasian power (China) to carve a permanent bridgehead into Spykman’s Eurasian maritime periphery. Against, this trend the United States has countered with President Obama’s Asian Pivot. However, the implementation of the Asian Pivot is limited by several post Cold War developments and certain constraints inherent in the geographic setting of the South China Sea. Beyond the South China Sea, the geographic setting favors the U.S. and its allies. Consequently, American options acting singly or in coalition with other nations, most notably Japan and Australia, remain more flexible and able to serve as a long term counterweight to Chinese force projection capabilities into the western Pacific proper.

Abstract The South China Sea, as ‘a non-volcanic passive margin basin’ in the Pacific, has often been considered as a small-scale analogue of the Atlantic. The recent ocean drilling in the northern South China Sea margin found, however, that the Iberian model of non-volcanic rifted margin from the Atlantic does not apply to the South China Sea. In this paper, we review a variety of rifted basins and propose to discriminate two types of rifting basins: plate-edge type such as the South China Sea and intra-plate type like the Atlantic. They not only differ from each other in structure, formation process, lifespan and geographic size, but also occur at different stages of the Wilson cycle. The intra-plate rifting occurred in the Mesozoic and gave rise to large oceans, whereas the plate-edge rifting took place mainly in the mid-Cenozoic, with three-quarters of the basins concentrated in the Western Pacific. As a member of the Western Pacific system of marginal seas, the South China Sea should be studied not in isolation on its origin and evolution, but in a systematic context to include also its neighboring counterparts.
