NEW YORK (Reuters) - The La Nina weather anomaly blamed for one of the worst droughts in the southern United States could revive this autumn, the U.S. Climate Prediction Center forecast on Thursday.
In its monthly report, the CPC said wind circulation consistent with La Nina was persisting in the central Pacific Ocean where the anomaly is usually born.
"Combined with the ... lingering La Nina state of the atmosphere, the possibility of a return to La Nina during the Northern Hemisphere fall (of) 2011 has increased over the past month," the CPC, an office under the U.S. National Oceanic Atmospheric Administration, stated.
