What is typhoon fireworks?

What is typhoon fireworks? Whenever there is a typhoon, the National Meteorological Administration will name and number the typhoon, which is convenient for everyone to distinguish and to better remind people to avoid risks. Let me give you a brief understanding of what typhoon fireworks are.

What is Typhoon Fireworks/KOOC-0/Typhoon Fireworks (English: strong typhoon In-Fa, international code: 2/KOOC-0/06) is the sixth named storm in the typhoon season of 202/KOOC-0/Pacific. Fireworks are provided by China and Macau.

165438+1October 20: 0017 (17utc12) was generated near the Marshall Islands, and then it continued to move westward.

165438+1October 20th, "Fireworks" was strengthened to a strong typhoon level.

1 65438+1October 2 1 day strengthened into a super typhoon [1].

165438+1weakened into a strong typhoon in the early morning of October 22nd.

165438+1October 24th, turning northeast.

165438+1At 08: 00 on October 26, the sea surface in the northwest Pacific Ocean south of Japan weakened into a tropical depression, and moved to the northeast at a speed of 50km/h, and the intensity continued to weaken. The Central Meteorological Observatory stopped numbering it.

Fireworks were upgraded to a tropical storm by the Central Meteorological Observatory at 2 o'clock on July/August, 20021[KLOC-0/5] and upgraded to a strong typhoon by the Central Meteorological Observatory. July 25th 12: 30 in Putuo, Zhoushan, Zhejiang.

July 25th, 20021year is the astronomical tide period. Before and after the landing of typhoon fireworks, there will be three encounters of wind, rain and tide in Zhejiang, Shanghai, Jiangsu and coastal areas, and the superposition effect is great. Typhoon fireworks moved to the northwest, and there was a strong wind of 13 in the northern part of Zhoushan Islands.

What is Typhoon Fireworks 2? It is a super typhoon, named storm no.26 in 20 15. "Fireworks" is provided by China and Macau, which means fireworks. In order to avoid confusion of typhoon names, relevant countries and regions decided to unify typhoon names at the 30th meeting of the Typhoon Committee of the World Meteorological Organization (WMO) held in Hong Kong on1October 25th-June 5438+February 10. Among them, tropical cyclones in the northwest Pacific and South China Sea adopt Asian style. The nomenclature table is the naming system of tropical cyclones in the northwest Pacific and South China Sea. The naming table *** 140 is provided by 14 member countries and regions in the Asia-Pacific region to which WMO belongs. The names of 10 provided by Chinese mainland are: Dragon King, Wukong, Jade Rabbit, Haiyan, Fengshen, Poseidon, Rhododendron, Dian Mu, Hippocampus and Begonia.

As can be seen from the above picture, typhoons are "threatening", mainly concentrated in Shanghai, Zhejiang, Jiangsu and surrounding areas. Typhoon is a kind of tropical cyclone. Tropical cyclone is a low-pressure vortex that occurs on the surface of tropical or subtropical ocean, and it is a powerful and profound "tropical weather system". What impact will it bring?

The direct disasters caused by typhoons before and after landing are usually caused by these "three killers"-strong winds, heavy rains and storm surges.

Causes of typhoon formation (this is also a common problem in geography and natural disasters in senior high schools)

1. On the vast tropical ocean surface where the seawater temperature is higher than 26.5℃, a large amount of seawater is evaporated into the air, forming a low pressure center.

2. With the change of air pressure and the movement of the earth itself, the inflowing air also rotates, forming an air vortex rotating counterclockwise, which is a tropical cyclone.

3. The continuous high temperature makes the tropical cyclone stronger and stronger, and finally forms a typhoon.
