THE INFLUENCE OF INTERACTION BETWEEN SHIFT OF WARM POOL AND THAT OF THE EQUATORIAL CONVERGENCE ZONE ON ATMOSPHERIC SURFACE WIND FIELDS DURING 1982/83 ENSO

Xia Youlong; Jiang dayong; Yang Dasheng

Abstract:

By using a linear and stationary atmospheric model (Luo and Jiang, 1994, Zebiak and Cane,1987) and the initial data coming from Zebiak and Cane (1987), the influence of interaction between shift of warm pool and that of the equatorial convergence zone (ITCZ and SPCZ ) on atmospheric surface stream field and divergence field during 82/83 ENSO is analysed by numerical experiments.The results show that SPCZ is more important than ITCZ in developing phase and mature phase of warm event.The interaction of warm Pool and SPCZ is stronger than that of warm pool and ITCZ in the two phases.SPCZ is as important as ITCZ in the initial phase and decline phase of warm event.
