%X The ECMWF (European Centre for Medium-Range Weather Forecasts) analysed data, the ECMWF/TOGA complementary data, the Climate Analysis Center/NMC (National Meteorological Center) outgoing long-wave radiation (OLR) data set, and the data set of China rainfall collected from 336 stations and archived at the Data Centre of the Institute of Atmospheric Physics (DCIAP) for the period of seasonal transition in the spring of 1989 were employed to study the thermal characteristics of the Tibetan Plateau and its neighboring regions, and their impacts on the seasonal transition in the Asian monsoon area. Special attention is paid to the diagnosis of the temporal and spatial distributions of surface sensible and latent heat fluxes. Results show that in 1989, the whole procedure of the outbreak of Asian monsoon onset was composed of three consequential stages. The first was the monsoon onset over the eastern coast of the Bay of Bengal (BOB) in early May. It was followed by the onset of the East Asian monsoon over South China Sea (SCS) by May 20, then the onset of the South Asian monsoon over India by June 10. The BOB monsoon was directly linked to the thermal as well as mechanical forcing of the Tibetan Plateau. It then generated favorable environment for the SCS monsoon onset, Afterwards, as the whole flow pattern in the tropical Asia shifted westwards, the onset of South Asian monsoon occurd.
