National Climate Center： this year the El Nino event occurs

CCTV News (news network): National Center for climate monitoring data shows that large parts of Equatorial Eastern Pacific SST, in May this year compared with the annual average high more than 0.5 degrees, has entered the State of El Nino.

"El Ni?o" refers to the Equatorial Eastern Pacific Ocean Ocean wide phenomenon of the abnormal warmer, because it comes from the ocean, but the atmosphere around it. A little warmer, will have a major impact on the global average temperature. El Ni?o years, average global temperatures will rise by 0.1 ℃, and if global average temperature rises 1 c, no ice throughout the Arctic Circle for half a year in the State. El status is sustained and developed to El Nino events would make it prone to severe weather in the world.

At present, this state of high sea surface temperature continues, and is already almost certain to be this year's El Nino event occurs. Experts this will likely be an impact on precipitation patterns in China this fall, may appear cold and rainy in South China calamities, autumn drought may occur in the North, early frost date can be earlier in autumn grain production areas in Northeast China.

Information at the national climate Centre shows that since 1950, worldwide there were two severe El Ni?o events, 1982-1983 and 1997-1998, respectively, to recent 1997-1998 strong El Nino events, for example, killed at least 20,000 people, global economic losses of up to more than 34 billion dollars, have taken place in many countries around the world during severe droughts and floods, resulting in global food production is about 20%. Therefore, early prevention, harm reduction, is particularly important.
