Super Typhoon in the Indian Ocean affects Vietnam

An unusual sign of the weather this year when the super typhoon in the Indian Ocean will affect the weather in our country today or tomorrow, the Center for Meteorological and Hydrological Forecasting (DBKTTV) said.

Accordingly, this decaying super typhoon combined with a local weather development caused rain on most of our country from the end of last week to the beginning of this week.

Super storm named NARGIS strong 14-15 level. Appearing on the Bay of Bengal in the Indian Ocean, west of Vietnam, it landed in Myanmar on May 3, killing at least 351 people and 75% of houses in the capital Rangoon destroyed and causing power outages throughout the city. .

Due to the wide range of activity, NARGIS stormed the equatorial low range from the southern hemisphere and pulled it north. The rapid movement of this low equatorial strip caused the rainy season in the South and Central Highlands to begin, earlier than half a month compared to the average of many years, and was beyond the predictions of domestic meteorological and hydrological experts. as international.

In many parts of the South and Central Highlands, heavy rain occurs on a large scale, causing flooding in many places. Dr. Bui Minh Tang, Director of DBKTTV Center commented that it was 'an unusual sign'.

Not stopping there, the NARGIS storm remnants are heading west of our country. At that time, it will combine with a part of cold air moving from mainland China to cause a large shower on North and North Central in the first two days of the week, between 5 - 6 / 5.

Weekend, the second storm

According to the European Mid-term Meteorological Center, around the end of this week, on 11-12 May, it is likely to form a second storm in 2008 in the offshore area of ​​the Philippines .

There has not been any storm reporting center to confirm whether the storm has moved into the South China Sea. However, meteorological analyzes at home and abroad have identified the early occurrence of storms as a warning of meteorologists in Vietnam and the world is becoming a reality.

Accordingly, in 2008, there will be about 33 storms, of which about 19 strong storms occur in the Western Pacific and South China Sea. Still according to the head of the DBKTTV Center, the phenomenon of La Nina started to appear from the autumn of last year has grown most strongly in the last months of 2007.

At the beginning of 2008, La Nina began to weaken and, from March, it weakened rapidly and the most obvious manifestation was the colder sea surface temperature in the central region but warmer in the eastern equator of Thai Binh. Ocean.

'Latest climate diagnostics show up to five of the six forecast models of Australia, India, Indonesia, Hong Kong, etc., unifying the ENSO phenomenon (ie, an intermediary between El Nino and La Nina) is returning in the summer of 2008, creating good conditions for unusual storms and developments' - Dr. Bui Minh Tang said.

Picking a stronger rainy season than usual?

Asked: 'So this year's rainy and stormy season compared to other years is likely to happen?' - Dr. Tang said that a stormy season and a stronger flood than normal are likely to occur in our country in 2008. 'This is not only meteorologists in Vietnam, but also many countries in the region. and international recognition is the same as that ' - Dr. Tang continued.

According to the latest forecast by meteorologists Hong Kong, among 33 storms appearing in the Western Pacific this year, there will be 19 strong storms from level 10 or higher. Remarkably, they guessed that about six to eight strong storms would face the Vietnamese coast.

The analysis of leading professors from Huong Cang University added speculation, after a year of strong development of La Nina, the Pacific Northwest is likely to receive an unusually rainy season.

Research from 2000 up to now by meteorologists Johnny CLTrung, Cu An Thi, Cheuk-Lam Lam (Huong Cang University, China) pointed out that in 12 years there is La Nina phenomenon, up to six years of high storm unusual) and two years under normal. These unusually high storm years occur immediately in the year preceding the year of La Nina.

That means, after La Nina weakened in March last year, the possibility of abnormal rainy season can be repeated according to the law. Bui Minh Tang said that such an abnormality saw a clear expression in Vietnam.

'Evidence is that in January 2008, two tropical depressions appeared in the South China Sea and caused heavy seasonal rains in the Central and the South. Assuming that two tropical depressions were the remnants of the 2007 hurricane season, but, in mid-April, the occurrence of a very strong storm in the South China Sea (storm No. 1) shows that the storm season is early and unusual.
