According to the features of the spatial characteristic vectors, the characteristic vectors that have been obtained with EOF method can be used as the ordered orthogonal radixes to unfold the phase space. After the corresponding time functions are embedded in phase space, the traces of the state vectors of the regional ozonosphere dynamical system are constructed, and can be used to describe the attractor integral information of the asymptotic state of the regional ozonosphere system and the dynamical features of the regional ozonosphere system, and then the embedded saturation dimension of the regional ozonosphere system attractor is successfully obtained. Based on these works mentioned above, by using the time function series we solve a problem contrary to the numerical solution and retrieve the control parameters of the state equations in which quadratic nonlinear terms are included, and then the dynamical models that can objectively reflect the temporal variation of the regional ozonosphere system are finally established.展开更多

The result indicates that the areas spacially correlated between SST and ozone layer in January greatly differ from the ones in July and they show opposite tendency in the signs of correlation, so do the teleconnection pattern for the ozone lay6r due to effects of SST in different seasons. In addition, persistent' influence of SST on the ozone layer results insuperposition of seasonal SST effects on the layer and makes it characteristic of well-defined wavetrainsin responses to SST. It is concluded that SST in the tropical eastern Pacific is of great importance to thenorthern ozone layer distribution and its seasonal evolution.展开更多
