Letter to the editor: Are the North Atlantic Oscillation and the Southern Oscillation related in any time-scale?
International audience The North Atlantic Oscillation (NAO) and the Southern Oscillation (SO) are compared from the standpoint of a possible common temporal scale of oscillation. To do this a cross-spectrum of the temporal series of NAO and SO indices was determined, finding a significant common osc...
