Abstract : The amount of convective cloudiness over Southeast Asia during the summer monsoon responds to synoptic scale circulation changes. Minimum cloudiness of less than 3/10 over the Red River Delta occurs under lower tropospheric ridging. Case study analyses of the synoptic changes which produce sufficient ridging in depth are presented to demonstrate (1) clearing in advance of typhoons, and (2) the early July singularity of 5 to 7 days of fine weather over North Vietnam and southern China caused by the northward progression, from the equatorial region, of the 'buffer' system. A case study is also presented to show the combination of synoptic changes which are favorable for the development of tropical storms in the South China Sea. (Author)
