摘要：

This paper deals with numerical experiments based on the coupled ECHAM-HOPE model. The results of experiments are analyzed. The initial fields for the calculations over time periods from one month to one year are constructed based on the results of the data assimilation of temperature profiles from TOGA-TAO moorings. The perturbations of the initial fields and the propagation of these perturbations with specific computational time intervals are analyzed on the basis of the results of these experiments. It is shown that the strongest impacts of the perturbations are localized in specific regions of the World Ocean corresponding to the energetically active zones of the Earth. The mechanism of the transition of these perturbations is also studied. Different statistical properties of the ensemble of experiments are presented.
