作者：符淙斌 Henry Diaz 范慧君 Institute of Atmospheric Physics Academia Sinica and CIRES University of Colorado Boulder CO 80309 USA NOAA / ERL 325 Broadway Boulder CO 80303 USA State Meteorological Administration Beijing 100081his paper analyzed the variations of latent heat flux (LHF) over the tropical Pacific in the period 1978-1988 by using COADS (Comprehensive Ocean and Atmospheric Data Set). It has been founded that the interannual variabili ty of LHF exhibits strong ENSO signal with the significant increasing LHF during the recent two warm events i.e. 1982 / 83 and 1986 / 87 and decreasing LHF in the cold episodes. However the longitudinal distribution of the LHF departures varies from event to event. In the eastern Pacific the specific humidity difference at air-sea interface (qs -qa) makes a dominant contribution to the interannual variability of LHF ( r = 0.73 ) while in the western Pacific the surface wind speed W and the qs - qa make nearly equal contribution to that of LHF.

作者：钟青纪立人 Institute of Atmospheric Physics Academia Sinica Beijing 100080 Institute of Atmospheric Physics Academia Sinica Beijing 100080n extended ocean-atmosphere coupled characteristic system including thermodynamic physical processes in ocean mixed layer is formulated in order to describe SST explicitly and remove possible limitation of ocean-atmosphere coupling assumption in hydrodynamic ENSO models. It is revealed that there is a kind of abrupt nonlinear characteristic behaviour which relates to rapid onset and intermittency of El Nino events on the second order slow time scale due to the nonlinear interaction between a linear unstable low-frequency primary eigen component of ocean-atmosphere coupled Kelvin wave and its higher order harmonic components under a strong ocean-atmosphere coupling background. And on the other hand there is a kind of finite amplitude nonlinear characteristic behaviour on the second order slow time scale due to the nonlinear interaction between the linear unstable primary eigen component and its higher order harmonic components under a weak ocean-atmosphere coupling background in this model system.

However more attention has been paid to the first and the second aspects because a large number of papers in the reference literature for preparing and organizing this paper are concentrated in the tropical Pacific Ocean such as the ENSO process with its climatic effects and dynamics and the monsoon-related air-sea interaction. The literature also involves various phenomena with their different time and spatial scales such as intraseasonal annual interannual and interdecadal variabilities in the atmosphere/ocean interaction system reflecting the contemporary themes in the four-year period at the beginning of an ara from the post-TOGA to CLIVAR studies. Apparently it is a difficult task to summarize the great progress in this area as it is extracted from a large quantity of literature although the authors tried very hard.
