How strong is Typhoon Hagupit making landfall and what kind of damage will it cause?

Typhoons are a type of tropical cyclone. A tropical cyclone is a low-pressure vortex that occurs over the tropical or subtropical oceans and is a powerful and deep "tropical weather system".

Tropical cyclones in the South China Sea and the Northwest Pacific are classified into six categories according to their maximum average wind strength (wind speed) near the center of the bottom layer, of which those with winds of 12 or more are collectively referred to as typhoons.

The formation of a typhoon requires the following conditions: the sea surface water temperature is above; a certain initial perturbation of positive vorticity; The ambient wind has less shear in the vertical direction; Low pressure or cloud disturbances at least a few degrees from the equator. Since the formation of typhoons is not well understood so far, the above list is only necessary for the formation of typhoons.

On August 1, Typhoon No. 3 "Senlak" and Typhoon No. 4 "Hagupit" formed one after another, breaking the rare "empty platform" situation of more than a month. Typhoon "Senlak" has made landfall in Vietnam and is gradually weakening in intensity. Typhoon "Hagupit" is rushing to the eastern coast of China, and is expected to make landfall along the coast from Wenling to Cangnan in Zhejiang Province from the night of the 3rd to the early morning of the 4th, becoming the second typhoon to land in China this year.

In order to cope with the adverse effects of weather such as typhoons. At 12 o'clock on 2 August, the Office of the National Flood Control and Drought Relief Headquarters launched an emergency response to flood control and typhoon control. The Fujian Provincial Flood Control and Drought Relief Headquarters upgraded the typhoon emergency response to Level III at 5 p.m. on August 2. <>

Before the introduction of international rules for the naming of typhoons, different countries and regions had different names for the same typhoon. In order to help people prevent typhoons and strengthen international and regional cooperation, the Typhoon Committee of the World Meteorological Organization (WMO) held its 30th meeting in 1997 and decided to adopt a unified naming system for tropical cyclones (typhoons) in the Northwest Pacific and the South China Sea from January 1, 2000.

The naming method is to create a naming table in advance and then reuse it in a sequential cycle year after year. The list consists of 140 namesWhen a typhoon name is used, causing great losses to one or more member countries, the name will be permanently removed and discontinued.

Typhoon "Hagupit" is small in size and has the characteristics of strong suddenness, and at present, from the satellite cloud image, the spiral structure is clear, but the size is not large, the intensity is average, and there is no typhoon eye at present.

Hagupit "had a maximum wind force of 13 near the center when it made landfall on the coast of Yueqing City, Zhejiang Province, and a typhoon of this magnitude could damage roofs, blow tiles away, break tree branches, and feel great resistance to move forward."

It can cause serious traffic impacts, water supply, power supply, communication interruptions, and other problems.

Typhoon Hagupit has a maximum wind force of 13 when it makes landfall, which will cause some buildings to be damaged, and many large trees and public buildings will be damaged, which is very destructive!

It will destroy the infrastructure of coastal cities. When a typhoon makes landfall, it will blow over the green belt and small objects in the traffic lights, causing traffic in the city to not operate normally.

The wind force in the center of the eye of the storm is about 13, and the maximum wind force in Mangkhut is 14, and Hagupit may damage the city's power and communication systems.

Typhoon Hagupit will have a wind force of about 12 when it makes landfall, which will threaten the lives and property of the local people, and houses will collapse wherever the typhoon passes.

Typhoon. "Hagupit" was named at 20 o'clock on August 1, 2020, and then moved all the way to the northwest, gradually strengthening in intensity, and was upgraded to a typhoon by the ** Meteorological Observatory at about 14 o'clock on August 3, and landed on the coast of Yueqing City, Zhejiang Province at around 3:30 a.m. on August 4, with a maximum wind force of 13 (38m s) near the center at the time of landfall, and then it crossed Zhejiang and Jiangsu provinces, and moved into the Yellow Sea at about 6 o'clock on August 5 from Yancheng, Jiangsu Province and strengthened again.

2. Typhoon Hagupit (International Number: 2004, Joint Typhoon Warning Center:

03W, Philippine Bureau of Atmospheric Geophysics and Astronomy: Dindo) is the fourth named storm of the 2020 Pacific typhoon season. The name "Hagupit" is provided by the Philippines and means whip.

1. Typhoon Hei Limb Chaigbi made landfall in Yueqing, Zhejiang Province at around 3:30 on August 4. Wenzhou and Taizhou in Zhejiang will be affected. Zhejiang Provincial Defense Finger:

The anti-typhoon emergency response was activated at 12 o'clock on August 2, and the anti-typhoon emergency response was upgraded to the level at 10 o'clock on August 3.

2. Wenzhou Meteorological Observatory: The blue warning signal for typhoons in Wenzhou was issued at 9:59 on August 2, and the blue warning signal for typhoons in Wenzhou was upgraded to a yellow warning signal for typhoons at 20:12 on August 2. Taizhou City Defense Finger:

At 12 o'clock on August 2, the anti-typhoon emergency response was activated.

Typhoon No. 4 "Haguppi" in 2020 made landfall on the coast of Yueqing City, Zhejiang Province at around 3:30 a.m. on August 4, with a maximum wind force of 13 at the center at the time of landfall. Bent chain source.

According to the statistics of the local meteorological department, from 8 o'clock on August 3 to 11 o'clock on August 4, the average precipitation in Yueqing was 257 mm, and the urban area of Yueqing was seriously waterlogged, and the depth of water accumulation in low-lying areas reached about 1 meter, many vehicles were soaked in water, and the trees on both sides of the road were blown down. The local fire department, sanitation and other relevant departments are strictly deployed and actively handled.

Wenzhou learned from the Emergency Management Bureau of Wenzhou City, Zhejiang Province on August 6 that according to incomplete statistics, due to the impact of the typhoon, a total of 31 towns (streets) in Wenzhou City were seriously affected, with a population of 10,000 people, 25 collapsed houses, and 2,088 temporary sheds at construction sites; 10,000 acres of crops affected by disasters, 10,000 acres of disasters, and 10,000 acres of harvests; 1.12 million households were cut off, 7 highways in the territory were all closed, 29 county and township roads were interrupted, 3,907 communication base stations were interrupted, 3,411 trees were affected, and the city's infrastructure was seriously damaged; Some towns in Longwan, Yueqing and Yongjia are seriously waterlogged. Wenzhou City has a direct economic loss of 100 million yuan.

This year's No. 4 typhoon "Hagupit" landed in Yueqing, Wenzhou in the early morning of August 4, and the Wenzhou Emergency Management Bureau attached great importance to the recovery of the disaster while doing a good job in all-round anti-typhoon. In order to accurately grasp the disaster situation and post-disaster reconstruction progress in various places due to the typhoon, on August 5, the Wenzhou Emergency Management Bureau dispatched the Zhejiang Provincial Emergency Department to be stationed in Wenzhou for air rescue in a timely manner according to the weather conditions, and assigned relevant disaster prevention and mitigation experts and observers to Qidu Island, Lucheng District, Wenzhou, Yueqing, Yuecheng, Shifan, Yongjia Sanjiang, Yantan and other five areas seriously affected by the typhoon to carry out air post-disaster inspections, and the whole flight time lasted 3 hours and 40 minutes.

Wenzhou "emergency people" have always been based on the emergency concept of "preventing floods, preventing strong Taiwan, grabbing major dangers, and relieving major disasters", and have studied and judged in a timely manner, acted quickly, and taken effective measures, and resolutely fought the first battle of preventing Taiwan in this year, so as to truly make the emergency rescue "urgent" in time and "rescue" in action, which reflects the importance and necessity of aviation emergency rescue in greater value, and provides reliable parameters for the next step of disaster relief and recovery work in Changzhou.
