| Session Description | There are rich spectrums in the variabilities of atmospheric and oceanic motions in the tropical Indo-Pacific ocean and Asian monsoon regions. On the synoptic time scale (2-10 day), summertime synoptic waves and equatorial modes are often observed, and they might 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 time scale, there are two-way interactions between the El Nino-Southern Oscillation (ENSO) and the Asian monsoon/Indian Ocean. The origin of the tropospheric biennial oscillation (TBO) might arise from the ocean-atmosphere interactions in the monsoon/warm pool regions. Papers in this session will discuss progress in the dynamics and thermodynamics associated with tropical atmospheric and oceanic variability and in revealing new phenomena using satellite and in-situ observations in terms of their structure, propagation and evolution characteristics. New results on coupled and uncoupled climate model simulations of both the mean state and the variability modes of the Asian monsoon and Indo-Pacific climate, seasonal climate forecast, scenario projections of near-term and long-term climate changes of the 21st century over the Asian monsoon and Indo-Pacific region will be discussed. The focus is on integrating observations, theories, and numerical simulations to advance our understanding of dynamics of atmospheric and oceanic motions on synoptic-to-interannual time scales 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 monsoon region, including climate model simulation and prediction. |
