What is Typhoon Fireworks
What is Typhoon Fireworks? Whenever a typhoon appears, the National Meteorological Administration will name and number the typhoon, which is convenient for everyone to distinguish typhoons, and also to better remind people to avoid risks. Let me give you a brief understanding of what is Typhoon Fireworks 1
Typhoon Fireworks (English: Severe Typhoon In-Fa, international number: 2). "Fireworks" was provided by Macau, China.
It was formed near Marshall Islands at 2: on November 17th (12: UTC on November 17th) and then continued westward.
On November 2th, "Fireworks" was strengthened to a strong typhoon level.
on the morning of November 21st, it intensified into a super typhoon [1].
in the early morning of November 22nd, it weakened into a strong typhoon.
on November 24th, it turned to the northeast.
At 8: on November 26th, 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 5km/h, and the intensity continued to weaken, so the Central Meteorological Observatory stopped numbering it.
"Fireworks" was upgraded to a tropical storm by the Central Meteorological Observatory at 2 o'clock on July 18th, 221, and upgraded to a strong typhoon by the Central Meteorological Observatory at 11 o'clock on July 21st [15]. It landed in the coastal area of Putuo, Zhoushan, Zhejiang Province around 12: 3 on July 25th, with a maximum wind force of 13 (38m/s) near the center, and landed again at the coastal area of Pinghu, Jiaxing, Zhejiang Province around 9: 5 on July 26th.
July 25th, 221 is in 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, which will have a great superposition effect [7]. Typhoon Fireworks moved to the northwest, and there was a 13-level gale in the northern part of Zhoushan Islands. What is Typhoon Fireworks 2
It is a kind of super typhoon and the 26th named storm in 215. "Fireworks" is provided by Macau, China, which means fireworks. In order to avoid the confusion of typhoon names, the countries and regions concerned decided to standardize the naming of typhoons at the 3th meeting of the Typhoon Committee of the World Meteorological Organization (WMO) held in Hong Kong from November 25th to December 1st, 1997. Among them, tropical cyclones in the northwest Pacific Ocean and the South China Sea were named with Asian styles, and the naming method was as follows: a naming table was made in advance, and then it was recycled year after year in sequence. The nomenclature table is the naming system of tropical cyclones in the northwest Pacific and South China Sea. The naming table contains 14 names, which are provided by 14 member countries and regions in the Asia-Pacific region to which WMO belongs. The ten names provided by Chinese mainland are: Dragon King, Wukong, Jade Rabbit, Haiyan, Fengshen, Poseidon, Rhododendron, Dian Mu, Hippocampus and Haitang.
As can be seen from the above picture, typhoons are "threatening", which are mainly concentrated in Shanghai, Zhejiang, Jiangsu and surrounding areas in recent days. Typhoons are a kind of tropical cyclones. Tropical cyclone is a low-pressure vortex that occurs on the tropical or subtropical ocean surface, 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 killer weapons"-gale, rainstorm and storm surge.
Reasons for the formation of typhoons (this is also a common question 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 more and more powerful, and finally forms a typhoon.
