The Tropical Biennial Oscillation (TBO) in coupled GCM simulations over the Indo-Pacific region in IPCC-AR4 scenarios of 280 (PI) and 720 (FS) ppm of $CO_2$ (both stable) are investigated. In many models, TBO is more prominent in FS in Nino3.4 SST and rainfall but less prominent in Indian Ocean SST. TBO, as primary mode (mode with highest power), is simulated by more models in Indian and Australian rainfall during FS. Thus, the Indo-Pacific teleconnection through Walker circulation rather than local forcing over the Indian Ocean could be responsible for increased TBO in Indian and Australian rainfall.
