What happens if two typhoons are too close together? If two typhoons merge, will the typhoon strengt

It should not be called a typhoon, but should be called a tropical cyclone first.

If two tropical cyclones are too close together, the Fujiwara effect can occur. The Fujiwara effect is also commonly known as the two-typhoon effect, but it is not limited to whether there are only two typhoons. When tropical cyclones interact with each other, the stronger storm will normally swallow up the weaker storm, resulting in a double eye typhoon.

One-way influence: If there is a large difference between the strength of two tropical cyclones, the strong cyclone will rotate the weak cyclone counterclockwise (Northern Hemisphere) or clockwise (Southern Hemisphere) around its outer circulation until the influence decreases beyond the effective distance and separates, or until the two merge. For example, the impact of Typhoon Tim in 1994 on Tropical Storm Vanessa.

Bidirectional influence: If two tropical cyclones are about the same intensity, they rotate counterclockwise (northern hemisphere) or clockwise (southern hemisphere) around the center of the circle until one of them weakens, with the center of the two lines as the center of the circle. For example, Typhoon Wayne in 1986 and Typhoon Vina in Typhoon Morakot and Swan in severe tropical storms Lionrock and tropical storm Nanchuan in severe tropical storm Mire and tropical storm Haima .

Typhoons are a category of tropical cyclones. In meteorology, according to the definition of the World Meteorological Organization, a tropical cyclone with sustained winds of 12 (i.e. meters per second or above) is called a hurricane or local synonym, and the name of the hurricane is used in the North Atlantic and the Eastern Pacific; And the synonym used in the western North Pacific (north of the equator, west of the international date line, east of 100 degrees east longitude) is typhoon.

Typhoons and hurricanes are both a type of wind, but they occur in different places and are called differently, typhoons are in the western North Pacific Ocean, west of the international date, including the South China Sea; Tropical cyclones in the Atlantic Ocean or the eastern North Pacific are called hurricanes, which means hurricanes in the United States and typhoons in the Philippines, China, and Japan.

Tropical depression, maximum wind speed 6 7, ( m s);

Tropical storm (tropicalstorm), maximum wind speed 8 9, (;

Severe tropical storm, maximum wind speed 10 11, (

Typhoon (ty-phoon), maximum wind speed 12 13, (;

Severe typhoon with a maximum wind speed of 14 and 15 (;

Super typhoon with a maximum wind speed of 16 ( .

Typhoon is the maximum typhoon from July to August of the lunar calendar. There are historical records of the second day of August 1954, July 27, 1996, and August 22, 2015. The three typhoons add up to more than 48 magnitudes.

Double typhoon refers to the occurrence of two or more typhoons at the same time, and the center spacing of these typhoons does not exceed 20 latitude distances, in this case, the winds will affect each other and a series of changes occur, this situation is called a double typhoon.

This is not possible, because the intensity difference between the two typhoons is sometimes large and sometimes small, resulting in an uneven distribution of the combined power, and eventually the two typhoons will not be able to merge. The same is true for three or more typhoons.

Due to the geostrophic deflection force, which is also known as the Coriolis force, a typhoon in the Northern Hemisphere rotates counterclockwise, and two counterclockwise rotating things collide to cancel each other out.

Two or more typhoons may merge and cause greater wind and rain together, last year's Typhoon No. 9 Nesat and No. 10 Haitang successfully held hands, and the most obvious typhoon Umbia currently affecting the Huanghuai region may also hold hands in the later stage, but it is cold air that is holding hands.

I don't think it's possible or even rare for two or more typhoons to merge into one typhoon. It's like two spinning tops that just collide.

Two typhoons need to be close to each other, but when they get close enough to a certain distance, they will rotate around each other at a certain point in the line between them, and their subsequent paths will often become very mysterious.

It is possible for typhoons to merge into one, but this is only theoretical, and it seems that this has not happened in reality. The meeting is possible because the formation of a typhoon means that the place is low and the pressure is slightly higher nearby.

Possibly, because a stronger typhoon will affect the trajectory of a weaker typhoon, or a stronger typhoon will eventually swallow up a weaker typhoon.

Possibly. Because if two cities are very close to each other and have two different typhoons, they will merge over time.

Since it is called a typhoon, it is at least level 8 or higher. There is something called the Fujiwara effect in tropical cyclones, which talks about the combined effects of two cyclones. Two typhoons can affect each other, generally around the center line, but if there is a large difference, one will be dominated by the other.

However, the merger is basically impossible, unless one is withdrawn (weakened to a level 7 or below, and is no longer called a typhoon), and the other swallows up its remnants of the water vapor cloud system and re-intensifies.

Two typhoons will merge together, and the powerful one will merge as close to the other, and the powerful one will merge with the lesser one, resulting in a double typhoon effect, which is the Fujiwara effect. Such an outcome would bring about a particularly major disaster. Once landfalling, it will bring strong heavy rain and high winds.

In our country, the month is more common.

It is not possible for two or more typhoons to merge into one, because there are too many coincidences and instability in the process of typhoon formation.

Yes!

The last two named typhoons that happened hand in hand with Fujiwara were in 2017 with Typhoon No. 9 "Nesat" and Typhoon No. 10 "Haitang".

The most recent typhoon was in July 2017, when Typhoon No. 5 "Okulu" ate Typhoon No. 6 "Rose" and strengthened it.

There are generally three kinds of Fujiwara results. Large typhoons eat small typhoons, and small typhoons continue to run out of energy along with large typhoons or two typhoons.

The merger of the two typhoons exists. When two typhoons meet, as far as I know, there are 3 scenarios. First, a slightly stronger typhoon will affect the trajectory of a weaker typhoon.

Second, it is an enhanced version of the first scenario, where a stronger typhoon eventually swallows up a weaker typhoon. Third, if the two typhoons are of equal intensity, the situation is very complicated, and it is possible to attract each other and strengthen or repel each other to weaken.

It's not possible, it will only increase the level of disaster.

Of course, it will, just like two whirlpools in the water, spinning and turning, they turn together, strengthening into a bigger, more fierce dripping whirlpool.

In 1994, Typhoon PAT and Typhoon Ruth merged.

In 2011, Typhoon Ma-on annexed Typhoon Scorpion Tiger.

In 2017, Typhoon Oku annexed Typhoon Rose.

Principle: Double typhoon effect.

Fujiwara: Ah, ......There are many examples, it is possible to merge and strengthen, it is possible to merge and weaken, but most of them are close and far away, and the real merger is not common.

In summer, typhoons often occur in China's coastal areas, although typhoons are a kind of natural disasters with strong destructive power, but the arrival of typhoons can effectively reduce the local temperature and bring people a touch of coolness in the hot summer. Normally, typhoons are often accompanied by violent storms and rains, and if it is a typhoon with relatively strong wind strength, it is likely to cause great damage and damage to people. I don't know if you have ever thought about what will happen when two typhoons collide, will they offset or join forces?

Next, I will give you a detailed introduction.

During the typhoon-prone season, there may be two or more typhoons in some areas at the same time, and when the distance between the two typhoons gradually approaches, the double typhoon effect will occur. To put it simply, when the vortex of two typhoons is very close to each other, both typhoons will be affected by each other, resulting in a tendency to close to merge. Therefore, after the two typhoons hit, they will not be offset, but will join forces.

If there is a big gap between two typhoons of different levels, such as one being very strong and the other being very weak, then when two typhoons meet, the typhoon with weaker winds will be controlled by the typhoon with stronger winds, and then swallow up the typhoon with weaker winds. If the two typhoons are of the same magnitude and there is no difference between strength and weakness, then at this time, the two typhoons will rotate around the same center, that is, they will affect each other.

However, this mutual influence does not last long, and once one side shows a tendency to decline, the situation of mutual influence will be completely broken. Generally speaking, a relatively strong typhoon, when it encounters a weaker typhoon, will choose to annex and absorb it, so that the weak typhoon becomes a part of itself, that is, the strong and strong join forces. However, in this case, the two typhoons must be very close to each other.

If the two typhoons come, it will not be offset, but the power caused by the combination of the two will be doubled compared to the general one, and it will have an impact on the local coast, and these cities should strengthen their safety protection.

It is estimated that it will join forces. It may merge into a super typhoon.

In general, they cancel each other out, but depending on the direction of rotation, if they are the same, they will collide and form a large typhoon.

At present, the twin typhoons Chandu and Kangsen are approaching our country, and China's ** weather stations have continuously issued orange warnings for strong typhoons. These two typhoons are estimated to have a strong impact on Jiangsu, Zhejiang, Shanghai and Yilan County in Taiwan Province, with a radius of more than 150 kilometers.

1. Areas affected by double typhoons:

It is expected that this year's No. 14 typhoon Chandu will make landfall in Taiwan Province of China at 5 o'clock in the morning of the 12th, with a 12-level wind circle radius of 70 kilometers and a 10-level wind circle radius of 150 kilometers, which is the strongest typhoon in history. It has been characterized as a super typhoon by the Ministry of Meteorology, and the typhoon will land in Jiangsu, Zhejiang and Shanghai in China on the 13th, and will gradually weaken after the rotation in Hangzhou. In addition, this year's No. 13 typhoon Conson belongs to the tropical storm level, which has turned from Vietnam, and is expected to affect the waters near the Diaoyu Islands in China and the waters near Taiwan.

2. How to prevent it?

When the typhoon hits, the local government will do a good job in the relevant wind prevention responsibility and rescue work, and we, as ordinary people, should stay at home and cooperate with the work to prevent typhoons. Doors and windows should be closed, and if it is a coastal area, the ship should be driven back to the port and the port should be strengthened to prevent the ship from anchoring and running aground. All outdoor gatherings and dangerous work such as working at height should be stopped, and clothes on the windowsill or flower pots that are not fixed should be moved indoors to prevent others from being injured when a typhoon hits.

It is also advisable to prevent geological disasters such as flash floods and floods caused by heavy precipitation, and it is best to stock up on a small amount of food at home in case of emergency.

3. Double typhoon effect:

So what will be the impact of the twin typhoons? Twin typhoons lead to a twin typhoon effect, in which two typhoons form the shape of a gear cyclone, preventing hot air from being dispersed. At present, some areas of Zhuhai in China have been believed to withstand high temperatures, and the outdoor temperature has even been maintained at about 35 degrees, so the people of Zhuhai should also pay attention to heatstroke prevention and cooling.

Lianyungang in Jiangsu, Ningbo in Zhejiang, Fujian, Guangdong, Chongming Island in Shanghai, these areas may be affected.

It will affect the weather in our country, it will affect some parts of our country, it will also affect the work of our country, it will also bring some cold weather, and it will also bring stronger rainfall to some areas, and it will also affect the travel permit work of local residents.

It will seriously damage the surrounding buildings, and will also cause serious losses to the mausoleum, and will cause very strict chain damage, which is not conducive to the development of the market, and will also affect the lives of residents, etc.

For example, there is Shanghai, and then there is also Guangxi, Zhejiang, Sichuan, Jilin, Liaoning, Hainan, and then there is also Macau, Hong Kong.

Are the twin typhoons coming back?

In general, the most common interactions between two tropical cyclones can be divided into three categories:

One-way influence:

When a generally stronger and normally weaker tropical cyclone approaches each other, the stronger tropical cyclone dominates the path of the weaker tropical cyclone, causing the weaker tropical cyclone to rotate in an anticlockwise direction around it. For example, the impact of Typhoon Tim in 1994 on Tropical Storm Vanessa.

Mutual Influence:

When two tropical cyclones are of equal intensity, they will rotate around a common centre until they are affected by other weather systems, or one of them weakens. Examples include Typhoon Wayne and Typhoon Vina in 1986.

Merging: A stronger tropical cyclone may absorb a smaller tropical cyclone and make it part of its circulation. The situation is similar to that when Maggie absorbed the area of low pressure over the South China Sea in early 1999 (but only if it was close enough and that the weak tropical cyclone was not affected by other weather systems).

The double typhoon effect means that when two typhoons approach, they will form a ring around the connected axis and rotate in the counterclockwise direction of each other, and the center and position of the rotation are determined by the relative mass of the two typhoons and the strength of the typhoon circulation. When spinning, it is normal for one to go faster, the other to go slower, and sometimes it can be combined into one. This phenomenon was first observed by the Japanese meteorologist Dr. Fujiwara (Sakuhei Fujiwhara (1890-1965) in 1923 during a water flow experiment, so it is also called the Fujiwara phenomenon.

Although the dual typhoon effect is defined as two tropical cyclones rotating around a common center, the dual typhoon effect can be varied and does not necessarily involve two tropical cyclones circling a common center** It can be that one of the tropical cyclones completely dominates the direction of movement of the other, or that two tropical cyclones line up with each other, or that one follows the other, or that there is no double typhoon effect between them. As a result, whenever two tropical cyclones approach each other, the path of a tropical cyclone tends to become very difficult.
