They used ten years of pressure records at Canton (at 2.8B0 S\nin the Pacific) and upper level winds at Singapore.\nThe oscillation of surface and upper-level winds was remarkably clear\nin Singapore. Until the early 1980's little attention was paid to this\noscillation, which became known as the Madden and Julian\nOscillation(MJO), and some scientists questioned its global\nsignificance. Since the 1982-83 El Nino event, low-frequency\nvariations in the tropics, both on intra-annual (less than a year) and\ninter-annual (more than a year) timescales, have received much more\nattention, and the number of MJO-related publications grew rapidly."^^xsd:string; a dbpedia:Index_term .
