A tropical phenomenon felt round the world

In 1982-83, one of the most severe El Niños of the century produced an exceptionally broad wake of weather-related catastrophes around the world, including droughts, brush fires, floods, and typhoons. Weather, climate, and social scientists from NCAR studied these “teleconnections”—effects far from El Niño’s home in the tropical oceans. In 1985, a decade-long international field program, the Tropical Ocean and Global Atmosphere, TOGA, set out to better understand the dynamics of the tropical climate system.
