Exchange with Online youthMr. Tran Quang Nang, Head of the Weather Forecast Center of the National Hydrometeorological Forecast Center, said Typhoon No. 8 will reach levels 11-12, shock 14 when operating in the Hoang Sa archipelago, and then drop from level. .
“Currently, this storm has just entered the South China Sea, so we are concentrating on tracking the direction and level of the storm. It is not yet possible to identify the cause of the weakening, as well as the level of the storm when it hits. It comes to the mainland because from now until then .. away.
After the storm reaches Hoang Sa, there will be next information, people should pay close attention to preventive direction, “said Mr. Nang.
According to Ms. Le Thi Xuan Lan, former deputy director of the forecast department of the Southern Hydrometeorological Station, storm No. 8 after its passage through the Paracel Islands will devastate Hainan Island (China) and will be able to enter the area of Ha Tinh to Thua Thien – Hue.
According to Lan, the reason the storm weakens is due to friction, as it enters the continental shelf, the seabed will be shallower, more friction weakens the storm. Another reason that storms weaken due to nutrient energy is the gradual loss of temperature and humidity.
“Currently, cold air from the north is moving south. Initially, it was predicted that the storm would gradually drift south by cold air, but because the storm entered, the cold air was not strong enough to deflect Storm.
However, the cold air will cause the sea surface temperature to decrease, the humidity will decrease, these are two sources of energy that make the storm stronger or weaker, ”said Lan.
Other information provided by Ms. Lan is that by the time Storm No. 8 has just entered the mainland, there will be a risk that another storm will cross the Philippines into the South China Sea and become Typhoon No. 9. Ms. Lan cautioned that ships at sea need subjective Avoid in this period because the weather is quite difficult.
Currently, the American model predicts that Typhoon No. 9 will move north of Central, but because it is still far away, there are many factors that influence the direction of the storm’s movement.
