Session Description The climate variations over the Asia-Oceania region are known to be influenced by ENSO. The monsoon 2009 was a typical case with Indian Summer Monsoon Rainfall was deficit by 23%. The South-East Asian monsoon was also deficit. The monsoon was co-occurred with warming in the central Pacific region. This central Pacific warming (El-Nino Modoki) together with the mid- latitude influences has affected the summer monsoon rainfall over Asia-Oceania Region during 2009.

Recent studies have demonstrated that the east-west SST dipole mode in the tropical Indian Ocean, called the Indian Ocean Dipole (IOD), also has major impacts in the region. To exchange ideas and available data on those climate modes and their impacts in the region is essential for reducing the state-or-the-art climate model biases for improved seasonal prediction. The session outcomes will also help to assess future climate variations due to frequent occurrences of those climate modes under the global warming stress.

In this session we will attempt to

• discuss climate variations related to ENSO, IOD and their interaction with the regional monsoon systems
• determine impacts of ENSO and IOD on climate variability and climate change in the Asia-Oceania region
• clarify mechanisms that drive ENSO, IOD and their interaction with the regional monsoon systems, including interaction with intraseasonal oscillations
• discuss current seasonal prediction skills and model biases on the basis of the above
• discuss past climate variability on longer time scales in the Asia-Oceania region in order to have better perspectives on future climate variability under the global warming stress.

Papers are invited that address at least one of above issues related to the climate variability in the Asia-Oceania region.
