The El-Nino event beginning is predicted (not so beforehand), but intensity and duration remain unknown before the end of El-Nino. The criterion of intensity an El-Nino connected with change of standing of the South Pacific anticyclone, is constructed in (Astafieva, 2010) and influence of all southern part of Pacific ocean on intensity and evolution of process the El-Nino - La-Nina is shown. The present work is research continuation. The complex analyzed the series of global radio thermal fields from electronic collection IKI RAS GLOBAL-Field, and long-term climatic series. It is shown that the El-Nino - La-Nina affect process interannual fluctuations of the centers of atmospheric action of Southern hemisphere - three subtropical maxima and the Antarctic subpolar depression (with three depressions). Process can be the fluctuation of atmospheric circulation between hemispheres. Adequate prediction of intensity the El-Nino probably only with use of satellite monitoring which gives the necessary information over all ocean part of Southern hemisphere. Teleconnections connected with global process El-Nino - La-Nina are discussed.
Keywords: process El-Nino - La-Nina, centers of atmospheric action of Southern hemisphere, teleconnections, microwave satellite monitoring, global radio thermal field
