El Nino may have helped Magellan cross the Pacific
The El Nino phenomenon that has puzzled climate scientists in recent decades may have assisted the first trip around the world nearly 500 years ago.
Explorer Ferdinand Magellan encountered fair weather on Nov. 28, 1520, after days of battle through the rough waters south of South America. From there his passage across the Pacific Ocean may have been eased by the calming effects of El Nino, researchers speculate in a new study.
When an El Nino occurs, the waters of the Equatorial Pacific become warmer than normal, creating rising air that changes wind and weather patterns. The effects can be worldwide, including drought in the western Pacific and more rain in Peru and the west coast of South America.
Tree ring data indicate that an El Nino was occurring in 1519 and 1520 and may even have begun in 1518.
