A diagnostic analysis of 1997-1998 Enso episode and role of intra-seasonal oscillation in tropical atmosphere

摘要

On the basis of comparison of 1982/1983 strong ENSO processes, key characteristics such as rapid development, immense intensity and abrupt retreat are revealed with regard to the warm episode in 1997/1998, features governing the intraseasonal oscillation for the tropical Indian Ocean and the western Pacific during its onset and evolution of the ocean and atmosphere for the process are diagnostically studied in detail.
