Will polar vortices and typhoons meet? Polar vortex and typhoon, will they meet?

No, the definition of polar vortex is to be active in the polar regions, and typhoons generally do not meet the definition of typhoons if they move northward to mid-high latitudes at most, so the two will not meet. But the air that makes up the polar vortex and the air that makes up the typhoon can meet. Relatively speaking, a concept is not your major here Please also give me the definition of the profession There is no meaning of equal sign Severe convective weather is a phenomenon of extratropical cyclones, how can it be equal.

To put it simply, first, the whirlpool and typhoon really exert force are not in the same rhythm (that is, the season), and second, the two must reach their strongest strength at the same time. But it's not possible to do both. And both are in the same system, energy will circulate, and there will be no conflict.

This is a very good question, but if you don't explain it well, it's easy to get stuck in circles and can't explain it clearly. In fact, this problem does not require too much professional meteorological knowledge, and the knowledge of geography in middle school can be solved and explained very clearly. The answer is that the presence of polar fronts makes it almost impossible for the polar vortex and the typhoon to meet, and the typhoon will degenerate into an extratropical cyclone as it gradually moves northward into the polar vortex's control area, but this is not an encounter.

The polar vortex and the polar high pressure (belt), we know that in the atmospheric circulation system, there are two engines driven by heat, one in the tropics, forming a tropical depression belt. One is in the polar regions, forming polar high pressure bands. In the polar high pressure zone, for example, air shrinks and sinks when it is cold.

The air accumulates on the ground and radiates outward, forming the polar high pressure and the polar easterly winds. At high altitude, after the air shrinks and sinks, in order to ensure the continuity of mass, the air converges like a sinking zone and forms a vortex of low pressure at high altitude, which is called the polar vortex, that is, the polar vortex. It simply depicts the configuration of the middle and high-rise in the polar region, d is low pressure, and h is high pressure.

Due to the rapid sinking, this high-pressure system is usually very shallow and quickly turns into cyclonic low-pressure at very low altitudes. As a result, the polar easterly wind belt is also very shallow, and it quickly turns to a westerly wind when it reaches high altitude. As a result, there are strong high-altitude westerly winds from near the poles to near the subtropics.

Polar front system, we know that high pressure is a clockwise rotating (anticyclone) system, the north of the high pressure blows the south wind, and the south of the high pressure blows the north wind. The south wind blows from the low latitudes and represents the warm air mass, and the north wind blows from the high latitudes to represent the cold air mass. Due to the existence of geostrophic deflection force, the north and south winds in the northern hemisphere deflect to the right of the direction of movement, thus becoming easterly and westerly.

In the mid-latitudes, the polar high is in the north, while the subtropical high is near 30°N. There must be a low-pressure zone between the two high-pressures (mathematics tells us that there must be a minimum between the two maxima (continuous derivatives)), which is the subpolar low-pressure zone (didn't it seem strange at the time why the subpolar low-pressure zone existed). The area where the east-west winds meet is the extreme front area.

If there is a disturbance in the frontal area, the cold and warm air masses will move relative to each other, resulting in the formation of a frontal cyclone, which is often also formed, that is, an extratropical cyclone. <>

The Southern Hemisphere is not particularly clear about the situation, and in fact part of the cause of the ozone hole in the Southern Hemisphere is also driven by the polar vortex, which is more complicated to say, so let's look at the second point. In addition, we are all in the Northern Hemisphere, so we will be more familiar with the situation, so the next analysis will use typhoons and the Arctic Polar Vortex in the Northern Hemisphere as a standard. Typhoon:

After checking the data, it is currently known that the northernmost typhoon is the 15th super typhoon Bulavan in 2012, at 14 o'clock on August 29, 12, it weakened into a tropical depression in Tonghe County, Harbin City, Heilongjiang Province, and the ** meteorological observatory stopped numbering it at 17 o'clock. Here the latitude of Harbin is taken as the standard: 44°04 -46°40N, and 46°N is taken as the standard.

It is currently the northernmost place that can be reached. Secretly said the conclusion: they could not have met.

Or rather, the odds are extremely small, very small. To be precise, the air is circulating all the time, but when they meet, they are no longer their original selves (which does not meet the definition of meteorological phenomena), at least typhoons! In addition, it will not be possible to study the atmospheric system until it is cut into several separate small systems, but then it will be a different story, and if so, the Earth will have to go back billions of years.

Or maybe it's already destroyed. <>

In some extreme cases, I think there is a very small probability that it will happen, and it must happen in winter, the polar vortex is very long to the south or north, and there is a typhoon, so it is very unlikely that they will meet, and the consequences of the encounter are extremely serious, although the intensity of the typhoon will weaken rapidly, but the precipitation it will bring will be immeasurable.

Therefore, physical training is the basis for the cultivation of sports and tactical awareness, that is to say, no matter how good sports tactics are, without the support of strong physical fitness, they can only be on paper.

Most students still treat physical education as a perfunctory subject. Teachers also do not pay enough attention, and many physical education classes are taught in a perfunctory manner. At the same time, in the teaching of physical education, many basketball teachers only pay attention to imparting theoretical knowledge and ignore the cultivation of sports and tactical awareness, so that students cannot use tactical awareness in actual combat to improve the level of basketball.

Folk sports, traditional sports, folk sports, and national sports in all countries of the world are an important part of human sports culture. For a long time, the theoretical and practical research on these sports cultures has been a hot topic and focus in the academic circles.

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.

Repulsion or attract, one eats the other, you can check the Fujiwara effect.

Typhoon is a tropical cyclone developed by the warm and humid air flow of the northwest Pacific Ocean, tropical disturbance is the embryonic period of typhoon, generally the sea surface temperature is higher than 26 degrees can help the development of tropical cyclones, two typhoons meet to form a double typhoon effect (also known as the Fujiwara effect) will suddenly change direction, the circulation is large, the strong typhoon will swallow the weak typhoon.

First of all, it is simply impossible for two typhoons with opposite turns to meet, the typhoon in the northern hemisphere rotates counterclockwise, and the southern hemisphere clockwise, so this does not exist.

Depending on which level is higher, it is generally strong cold air, because the strong cold air is close to the surface and is very low.

If the strong cold air meets the typhoon, the strong cold air high pressure will fill the depression of the typhoon's low pressure.

Now it is possible to continuously observe Typhoon Ayu and the strong cold air that has begun to affect the mainland of China: the front of the strong cold air may meet Typhoon Ayu near Fujian or the Taiwan Strait on the 23rd, and Typhoon Ayu will completely disappear on the 24th.

Basic principles: 1. There is a large gap in energy levels. Typhoons are small- and medium-scale weather systems, and although their energy is huge, they are still extremely small compared to large-scale weather systems such as strong cold air.

2. The strong cold air changes and destroys the high temperature heat uptake and water vapor conditions near the ground required by the typhoon, making the typhoon a passive water, and the typhoon will die out quickly after being cut off from energy.

That's going to turn into a tornado.

Hot and cold air currents meet, and it rains.

They can merge into a big typhoon, depending on where the typhoon goes, but it's rare to meet because the formation of a typhoon means that there is a low pressure in that place, and there is a slightly higher pressure nearby.

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) at the centre of a tropical cyclone is called a hurricane, 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.

In Taiwan, Japan and other places, tropical cyclones (including tropical storms, severe tropical storms and typhoons as defined by the World Meteorological Organization) are referred to as typhoons. Every summer and autumn, many violent storms called typhoons occur in the northwest Pacific Ocean adjacent to Japan, some of which dissipate over the sea and some land and bring violent storms and rains, which are a type of natural disaster.

In the tropical ocean, the sea surface rises due to the direct sunlight and the temperature of the seawater, and the seawater is easy to evaporate into water vapor and disperse in the air, so the air temperature on the tropical ocean is high and the humidity is high, and the air expands due to the high temperature, resulting in a decrease in density and a decrease in mass, and the wind near the equator is weak, so it is easy to rise, and convection occurs, and at the same time, the surrounding colder air flows in and supplements, and then rises, so that the entire air column will eventually be the air with higher temperature, lighter weight and less density. This creates the so-called tropical depression.

However, the flow of air is from high pressure to low pressure, just as water flows from high to low, and the air at the higher pressure around it will flow to the lower pressure, and the wind will be formed. In summer, because the direct sunlight area shifts from the equator to the north, the southeast trade winds in the southern hemisphere cross the equator and turn into the southwest monsoon to invade the northern hemisphere, and meet the northeast trade winds in the original northern hemisphere, forcing the air to rise and increase the convection.

If the two typhoons rotate in the same direction, they may merge into a super typhoon, and it is estimated that the destructive power will be unprecedented; If the two typhoons rotate in opposite directions, the forces may cancel out a lot, and the destructive power of the typhoon will be greatly reduced, or even disappear.

If two typhoons collide, they are likely to be all Marys coming together, and there will be a very violent collision, and then the larger wind of Mary will swallow up the less powerful wind, and then form a bigger typhoon.

If the two typhoons rotate in opposite directions, the forces may cancel out a lot, and the destructive power of the typhoon will be greatly reduced, or even disappear.

If it is a relative typhoon, a stronger typhoon will be weaker, and if it is a typhoon that follows, the typhoon will be stronger.

Devouring each other, big swallowing small, but sometimes small swallowing big, (for example, in 2017, Typhoon No. 5 Okulu [Tropical Storm Category 8] and Typhoon No. 6 Rose [Tropical Storm Category 9], when Typhoon Oku swallowed Typhoon Rose).

There will be two scenarios, one will cancel each other out, and the other will be two combined into one bigger typhoon.

If it rotates in the same direction, it will form a large super typhoon, and if it rotates in the opposite direction, it may cancel out.

A collision between two typhoons is likely to cancel each other out or form a larger typhoon.
