Vietnam may suffer from heavy rain

La Nina phenomenon is gradually forming in the Pacific region, will cool the air and cause heavy rain in Asia, including Vietnam.

"Following the decline of the El Nino phenomenon raging around the Pacific and East Africa in early May 2010, the phenomenon of La Nina in the middle is developing in the Pacific tropical region," AFP quoted. statement of the World Meteorological Organization (WMO). "This phenomenon will become stronger and stronger over the next few months."

La Nina is a weather phenomenon that causes an unusually cold sea temperature in the equatorial eastern sea of ​​the Pacific.

At the end of 2008, La Nina caused an icy situation that killed dozens of people across Europe. This phenomenon also caused heavy rainfall in Indonesia, Malaysia and Australia, as well as drought in South America.

In Vietnam, in 2008, La Nina made summer cooler than usual. Especially Hanoi and the surrounding area suffered a record rain in 40 years. The torrential rain, continuously for many days at the end of October with a flow of approximately 1,000 mm, engulfed much of the capital's area.

According to Nguyen Lan Chau, deputy director of the Central Hydrometeorological Center, as well as in the Pacific and La Nina regions affecting Vietnam will make the temperature lower than the average of many years, rain and storms. more.

According to WMO, both La Nina and its antagonistic phenomenon, El Nino (an abnormal rise in sea temperature in the central and eastern equator of the Pacific), both break the normal and cause weather patterns. Unpredictable impact on a large scale to many parts of the world.

The head of the WMO Climate and Water Office, Rupa Kumar Kolli, said: "Normally La Nina will cause a major storm season in Asia and Australia. It also causes severe storms in the region. Tropical Atlantic Ocean So it will bring hidden dangers ".

However, Kolli also added that if La Nina really formed, it would reduce the air temperature that is heating up many areas of the world in recent days, including Vietnam.
