Аннотация:Statistical relationships between sea surface temperature (SST) in the equatorial Pacific (NINO3.4 region), zonal wind circulation L-phi around a latitude circle, and wind circulation L-S around contours enclosing various atmospheric centers of action and cyclone-active regions were studied depending on the time scale of averaged circulation time series. For this purpose, simultaneous correlation coefficients between a series of monthly mean SST in NINO3.4 and series of circulation around a latitude circle and contours were calculated using different time scales of averaged data. This allowed the estimation of an optimal time scale (or scales) on which the tropical ocean and the atmosphere interact. Regularities, similarities, and differences in the variation of correlations depending on the averaging interval applied to circulation series were found for various regions, latitudes, and pressure levels.
