As about 60% of humanity inhabits in this region, understanding the climate variability of this system is of crucial importance. The AAM interacts with the Indo-Pacific Ocean and has rich spectrums in the atmospheric and oceanic motions. On the synoptic timescale, synoptic wave activities are often observed, and they may trigger tropical cyclone genesis. On the intraseasonal scale, there are significant signals peaking at bi-weekly (10-20 day) and lower-frequency (20-70 day) bands. On the interannual timescale, there are two-way interactions between the El Nino-Southern Oscillation (ENSO) and the AAM in which the maritime continent is a key region for teleconnection between the tropical Pacific and the Indian Ocean. The origin of the tropospheric biennial oscillation (TBO) and Indian Ocean dipole/zonal mode might arise from ocean-atmosphere interactions in the monsoon/warm ocean regions. On the interdecadal scale, an overall trend of the global land monsoon precipitation may exist. Papers in this session will include new results in: (1) the multi timescale variability in the AAM and Indo-Pacific climate in general, (2) revealing new phenomena using satellite and in-situ observations in terms of their structure, propagation and evolution characteristics, (3) coupled and uncoupled climate model simulations of both the mean state and the variability modes of the AAM and Indo-Pacific climate, (4) seasonal forecast and scenario projections of future climate change over the AAM and Indo-Pacific region The focus is on integrating observations, theories, and numerical model simulations to advance our understanding of dynamics of atmospheric and oceanic motions on synoptic-to-interdecadal timescales and multi-scale interactions among them. A particular interest is the impact of ENSO, intraseasonal oscillations (ISO), TBO, and Indian Ocean dipole/zonal mode on the climate over the AAM region, including climate model simulation and prediction. |
