President EL NINO: WEATHER SCOURGE SWEEPS GLOBE by Stephen Strauss A year’s worth of bad weather for the world is turning out to be good news for meteorologists and oceanographers. Australians were parched under a record drought in January and Ecuador reeled from rains which in May were 15 times heavier than normal. A high- altitude wind current called the jet stream was diverted south from its normal path into a huge arc that crossed northern Mexico and the U.S. Gulf states — which were inundated with floods — before it swept up toward the Indonesia. the World Climate Research Program in Maritimes. The diverted jet stream Dr. Kikuro Miyakoda, head of Geneva, said that he estimated at least caused havoc with the weather Princeton University’s Geophysical 20 nations will join in monitoring future everywhere it went.
