An El Niño–Habagatan na Osilasyon iyo an pinakamainit na kabtang kan temperatura sa dagat midbid bilang El Niño asin an pinakamalipot na kabtang bilang La Niña. An Habagatan na Osilasyon iyo an kaibang elemento sa atmospera, na may kaibang temperatura sa dagat: an El Niño iniibanan nin halangkaw na pan-ibabaw na presyon sa tropikong solnopan na Pasipiko asin La Niña na may hababang presyon sa aire sa ibabaw diyan. Naghaloy an duwang peryodong iyan nin nagkapirang bulan an kada saro asin sa parate nangyayari kada pirang taon na nagkakalaenlaen an kosog sa kada panahon.
