La Nina," the abnormal cooling of Pacific Ocean surface temperatures, is as powerful as its brother "El Nino" and the effects of global warming on their cycle need to be monitored, UK scientists said on Wednesday. The La Nina weather pattern could prevent sweltering summers across the world this year, although it has also been associated with flooding in Asia and could bring more hurricanes to the Atlantic Ocean, according to forecasters."La Nina is just the flipside of El Nino, it's a cycle that goes around," said weather scientist Matt Huddleston, on the sidelines of a conference held by the Met Office, Britain's national forecaster."It's the biggest phenomena after the seasons. It's a natural cycle of warm water moving backwards and forwards across the Pacific, causing a lot of storms, a lot of atmospheric activity that has impact all around the globe."The better-known El Nino refers to an abnormal warming of surface waters in the eastern Pacific. It tends to occur every two to seven years and lasts for several months.Forecasters warn that if the El Nino-La Nina cycle were disrupted, the effects could be devastating,"Some people have even linked the rise and fall of civilizations to persistent El Nino phenomena in the past. If that balance did change, the impact on some communities could be catastrophic," Huddleston said.The El Nino was widely credited for restricting the impact of hurricanes in the Atlantic Ocean last year, and despite triggering floods and droughts like its counterpart, both parts of the cycle are important to global communities, Huddleston said.La Nina tends to follow the El Nino pattern. In 1997-1998, the biggest El Nino on record killed thousands of people.
