Cold surges and Borneo Vortex are the synoptic scale disturbances during the Asian Winter Monsoon period (November-March). These disturbances have closely linked with the growth of strong convective clouds and heavy rains in the western part of the Maritime Continent. This study is subjected to study impact of cold surges and Borneo Vortex to the against atmospheric and rainfall conditions over the western part of the Maritime Continent using compositing technique these parameters for the period of November-March 2004/02-2014/15. The highest frequency of cold surge events occurs in January, while the incidence of Borneo Vortex alone and their interaction occurs in December. The atmospheric parameters of vortices, divergence, and moisture transport indicate that the incidence of cold surge, Borneo Vortex and their interaction having different influences. Region of South China Sea is mostly affected by the most significant of the other regions. Cold surge has the impact of increasing rainfall in all regions except Central Borneo/Kalimantan Island, Borneo Vortex while increasing rainfall throughout the region except Java, and the interaction of both resulted in increased throughout the study area. This is preliminary study and it would be triggering further study, it was due to the lack study over Indonesia.
