The weather-pattern above the Indonesian region has been vary and fluctuation for physic-dynamic atmosphere related to the interaction between atmosphere and sea surface conditions. From those conditions, some regions in Indonesia received the big impact which is caused from natural disaster such as floods and landslides.
Based from the unstable-weather which is occurred for the months before, some descriptions about the analysis including its impact will be summarized by observing the atmosphere and sea surface development conditions above the Indonesian region from January to March 2002. All of the weather parameters which is analysed such as air-pressure, relative humidity, sea surface temperature, cloud activity and wind circulation-pattern from surface and beyond. Besides that, the developing of water vapour above sea surface has been counted related to the warming of sea surface on the Indonesian ocean. In this case, the formation of cloud could became the rainy day in the earlier 2002.
The identification for interaction between atmosphere and sea surface development conditions above the Indonesian region during the rainy season 2002 from January to March 2002 has been done using the daily-weather parameters i.e. air-pressure above the northern hemisphere and southern hemisphere, the analysis of cloud activity from GMS satellite, wind circulation from surface and beyond, sounding-data, sea-surface temperature and SOI Index. Those parameters will give the illustration about the conditions of atmosphere on the Indonesian region.
The yields from this research has shown the fluctuation of dynamic-physic atmosphere and sea surface condition along those periods. It caused the extreme-weather which is being impact such as floods and landslides in all of Indonesian provinces. The results obtained from this reserch will be presented in this papper.
