Abstract: The formation of anomalies of monthly mean atmospheric circulation was examined in relation to the interactions between the atmosphere and sea-surface temperature. It is indicated that in the current regions the ocean as a heat source exerts an deep influence on the formation of the anomalies of atmospheric circulation. But in the un-current regions thermal regime of the oceans are controlled by the atmospheric circulation.The persistence of anomalies of the atmospheric circulation was investigated.It has been found that in the temperate latitudes there are two minima in the annual course of persisence at Spring and Autumn. It is shown that March-April and September-October minima of persistence are very closely connected with the two maxima in the annual course of variation of heat source and sinks. In the lower latitudes there is only one minimum of persistence in the annual course. Analysis indicated that it may have some link with the annual variation of intensities of heat source over the Kuro-shio.The investigation of natural analogies showed that when the circulation or sea surface temperature anomalies for two month had similar characteristics, then the following months also had some similarity, but the similarity did not decrea-sed monotonously with increasing of the time interval. In the 4 th to 5 th month or in the 9 th to 11 th month apart from the beginning the similarity was much bigger than preceding and following months. From results mentioned above, it may conclude that only this very rhythm in atmosphere and ocean, indeed, makes the long-range weather forecasting possible.
