What is the origin of Typhoon Hagupit and how is it named?

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.

This time, Typhoon Hagupit made landfall in the coastal area of Yueqing City, Zhejiang Province, with a central wind force of 13, and was named Hagupit ** in the Philippine language, which means to whip the whip.

It is a central wind force of 13 that made landfall in the coastal area of Yueqing City, Zhejiang Province, and the name Hagupit is derived from the language of the Philippines, which means to whip the whip.

This year, Typhoon No. 3 "Senlak" and Typhoon No. 4 "Hagupit Bi" broke the "empty platform" situation. 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.

A uniform nomenclature system is adopted for tropical cyclones (typhoons) in the Northwest Pacific and the South China Sea.

Typhoons are a type of tropical cyclone, and the name "Hagupit" is provided by the Philippines, which means whip.

Whip, according to the Japan Meteorological Agency, the system was upgraded to a tropical storm by the agency on August 1, 2020, given the designation 2004, and given the designation Haguppi.

2. "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 about 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 Jiangbi Su provinces, and moved into the Yellow Sea from Yancheng, Jiangsu Province at about 6 o'clock on August 5 and strengthened again.

1. Typhoon Hagupit (English: 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. "Haguppi" is a jujube provided by the Philippines and means whip.

2. "Hagupit" was named at 20 o'clock on August 1, 2020, and then moved all the way to the northwest or rotten direction, gradually strengthening in intensity, and was upgraded to a typhoon by the ** Meteorological Observatory at about 14 o'clock on August 3, and at about 3:30 a.m. on August 4, it made landfall on the coast of Yueqing City, Zhejiang Province with near peak intensity, and the maximum wind near the center at the time of landfall was 13 (38m s).
