International Workshop on Development of Atmosphere-Ocean Coupled Models
towards Improvement of Long-range Forecast
Tokyo, Japan
8-10 December 2010

The Japan Meteorological Agency (JMA) held the International Workshop on Development of Atmosphere-ocean Coupled Models towards Improvement of Long-Range Forecast in Tokyo, Japan, 8-10 December 2010. The workshop consisted of an open public symposium (8 December) and a closed expert workshop (9-10 December).

Background and Objectives

The climate system in the Asia-Pacific region is a complex system dominated by the variability of the Asian monsoon, the ENSO and the Indian Ocean. The seasonal forecast in the Asia-Pacific region still remains one of the most challenging tasks. There is increasing evidence that explains seasonal variability and supports the feasibility of the seasonal forecast in this region. Recent researches have elucidated some mechanisms of the atmosphere-ocean coupled system in the Asia-Pacific region.

The Japan Meteorological Agency (JMA) introduced an atmosphere-ocean coupled model to the operational seasonal prediction in February 2010. On this occasion, JMA held the international symposium and workshop on development of atmosphere-ocean coupled models towards improvement of long-range weather prediction under the auspices of the Ocean Policy Research Foundation (OPRF)* of Japan.

The workshop aimed to review recent progress, remaining issues and discuss future prospects on the model development for the seasonal forecast in the Asia-Pacific region.

*Ocean Policy Research Foundation (OPRF)

   Ship & Ocean Foundation (SOF), alias Ocean Policy Research Foundation, was established in 1975. Under support from the Nippon Foundation, the private non-profit organization is undertaking activities related to a wide range of maritime issues. As the scope of its activities has expanded, SOF has recently adopted a new name, “Ocean Policy Research Foundation,” which better illustrates its current concerns and operations - multi-disciplinary researches into ocean-related issues to make practical policy proposals in the areas of marine environment protection, maritime security, marine resources preservation, etc. OPRF is headquartered in Tokyo.
