A TWO-DEMENSIONAL MODEL FOR CHAOTIC BEHAVIOR STUDY OF ATMOSPHERIC MERIDITIONAL CIRCULATION OF SOUTHEAST ASIA

Abstract

The purpose of this paper is to provide a chaotic analysis of atmospheric meridional circulation (AMC) of Southeast Asia by using a twodimensional model. The atmospheric meridional circulation is influenced by winter monsoon. This model is simplified from the atmospheric convective model with two-dimensional Cartesian coordinates (i.e. y − zplane) based on Lorenz model. The bsifurcation diagram of the twodimensional model is used for studying chaotic behavior in some range of the parameter F which represents an external forcing term (i.e. soil moisture) and parameter r which represents dimensionless convective term.
