Study on the seasonal Forecast Area of BMG

Interaction between Asian-Australian monsoon system and equatorial zonally circulation system within the Pacific-Indian ocean, are a major interest of the international scientific communities recently. Being within Asian- Australian monsoon region, and located between Pacific and Indian Ocean, the location of the Indonesia region becomes an important intersection of the two important global phenomena. On the otherhand, internal atmospheric dynamics are complicated. Tall cumulus clouds due to available moisture and energy source may generate deifference kinds of local phenomena within the maritime continent region. Eventhough Indonesian region is moist on relatively have abundant of rainfall, variability of rail fall amount is still one important climate variables to influence human activities in Indonesia. This is due to the fact that agriculture activities remain an important activities for Indonesian people, therefore it also important sector in Indonesian economy. In addition, hydropower plant are the main energy source for electricity. Consequently, industrial sectors are also heavily dependent on the water availability. Therefore, rail fall quantity in specific time and at particular place is closely relative to economic activities, and information on rainfall variability and predictability are important for water management.
