Why is the number 12 typhoon closer to the shore?

The director of the Central Center for Meteorological and Hydrological Forecasting stressed that the typhoon No. 12 will become stronger and more dangerous when approaching the shore, affecting on a large scale.

At 10 am on November 3, the position of the center of storm No. 12 (international name Damrey) is only about 400km away from the waters of Khanh Hoa - Ninh Thuan. At a speed of 20 km / h, in the early morning of November 4, Hurricane Damrey will directly affect the South Central and Central Central region.

Mr. Hoang Duc Cuong, Director of the Central Hydrometeorological Center and Mr. Nguyen Van Huong, Deputy Head of the Center's short-term Meteorological Forecasting Department, discussed with Zing.vn about the danger and how operation of storm No. 12.

The storm is stronger when approaching the shore

- Why is the intensity of the typhoon number 12 stronger when approaching the mainland?

- Mr. Hoang Duc Cuong: Storm No. 12 is gradually increasing the level and velocity when approaching the mainland of our country. When crossing Palawan Island (Philippines), the depression is quite weak because of friction. However, in the East Sea, the sea is open and there are not many obstacles, this tropical depression intensifies.

It is worth noting that in combination with cold air, it will cause a strong wind circulation on a large area, to the north. When preparing storms to land, wind intensity reaches level 10-12.

Moreover, entering warm waters is an ideal condition for Hurricane Damrey to gain energy. Combined with the cold air in the north pouring down, the wind of the storm will be stronger.

From November 1, the tropical depression developed into a storm. The location of Hurricane Damrey is quite close to our coast. Moreover, about 3-4 days after formation (tropical depression formed on October 31 - PV) is the most dangerous development period of the storm.

- Which area is most worrisome due to storms?

- Mr. Hoang Duc Cuong: The entire South Central region will directly affect storms. Provinces from Binh Dinh, Phu Yen to Binh Thuan will be located in the area of 7-8 winds, Ba Ria - Vung Tau will even have level 6-7 winds. Khanh Hoa and northern Ninh Thuan provinces will have the strongest winds, about level 12.

Influence associated with cold air from the North, Central region will have a heavy rain from 3-6 / 11. After that, rainfall decreases.

- Mr. Nguyen Van Huong: The most worrisome risk is the strong wind intensity and heavy rainfall. As we know, the South Central Coast recently had a rather heavy rain, causing flood in Phu Yen area. This time, this is also the area where the storm will land.

Along with the impact of cold air, heavy rain, prolonged, may occur in this key area, high risk of flood and flood. The key area influences from Quang Ngai to Ninh Thuan.

Will the storm be able to bend down to the South?

- On November 2, the Central Center for Meteorological and Hydrological Forecasting proposed two scenarios: storms caused flooding with the total rainfall can reach the lowest level of 500 mm, the highest is 1,000 mm. By now, what scenario is high likely to happen?

- Mr. Nguyen Van Huong : These scenarios are still in the plan of the meteorological agency. We will follow and update.

- Typhoon No. 12 is affected by cold air, is it possible to bend to the South region?

- Mr. Nguyen Van Huong: We also offer this plan, but the possibility of not high. Damrey will mainly land in the South Central region.

- The storm No. 12 appeared and operated after the near-shore tropical depression appeared in November in the southern sea, what is this unusual, sir?

- Mr. Nguyen Van Huong: Tropical depression and typhoon Damrey are located on the tropical convergence band, continuously with swirling swirling. This is not an unusual phenomenon.

- Da Nang is the place that is preparing for APEC High Week. Weather in the coming days like?

- Mr. Hoang Duc Cuong: I think there is nothing to worry about. This area is only affected, prolonged heavy rain. However, according to our judgment, the rainfall is concentrated in 4-5 days and 11 November then gradually decreases.
