Abstract:
In this project I am interested in studying the possible inter-relationship changes between the Asian-Australian monsoon (A-AM) system, tropical biennial oscillation (TBO), and ENSO in response to various scenarios of future 21st-century greenhouse gas and aerosol emissions. Previous studies, which include both observations and simulations, have suggested that the TBO is likely an inherent mode of A-AM system surrounding the Indian Ocean basin but subjected to the influence of remote ENSO forcing. In view of monsoon prediction perspective, impacts of future climate change on this paradigm will have profound socioeconomic consequences. Understanding the ocean roles in the future warmer climate in affecting the monsoonal TBO phenomenon is therefore essential. The required WCRP CMIP3 datasets for thrusting into the proposed tasks are at least monthly-mean temporal resolution of rainfall, winds, specific humidity, temperature at various levels of troposphere, and heat flux terms at the air-sea interface and land surface, in addition to the sea surface temperatures.
