Is an extratropical cyclone a typhoon? Is a typhoon a tropical cyclone?

A typhoon is a tropical cyclone, and an extratropical cyclone is not a typhoon. But a strong extratropical cyclone, similar to a typhoon, can wreak havoc.

No, a typhoon is a tropical cyclone with a warm-hearted structure in the center and an extratropical cyclone is a cold-hearted structure.

The air on the periphery of the eye of the typhoon rotates too much, and under the action of centrifugal force, the outside air does not easily enter the central area of the typhoon, so the eye area of the typhoon is like an isolated tube surrounded by a wall of clouds. This is the eye of a typhoon, the air of a tropical cyclone rotates very quickly and can form a typhoon eye, while an extratropical cyclone has a weak force, the central pressure is unstable, and the direction of air flow is not clear, making it difficult to form a typhoon eye.

Typhoons are tropical cyclones, and extratropical cyclones are different in nature from tropical cyclones.

An extratropical cyclone is an extratropical cyclone Typhoon is a tropical cyclone Tropical cyclones can degenerate into extratropical cyclones in the middle and high latitudes due to the influence of the westerly wind belt.

No, a tropical cyclone is a typhoon.

Extratropical cyclones can transform into tropical cyclones under certain conditions, such as Typhoon White Dolphin. Of course, tropical cyclones can also be converted into extratropical cyclones, such as a typhoon that turns warm after landfall. Because of this, many meteorological services have different judgments on the nature of a particular cyclone.

There is a disagreement about the mechanism of some cyclones, and the JTWC considers it to be warm gas, and JMA believes that it is hot gas.

A typhoon is a tropical cyclone.

A tropical cyclone is a low-pressure vortex that occurs over the tropical or subtropical ocean, and is a powerful and deep tropical weather system. Tropical cyclones usually form over the sea surface (e.g., Northwest Pacific, North Atlantic, Indian Ocean) 3-5 latitudes away from the equator in the tropics, and their movement is mainly influenced by Coriolis forces and other large-scale weather systems, and eventually dissipates over the sea, or degenerates into extratropical cyclones, or dissipates after landfall. Tropical cyclones that make landfall can bring serious property and people** and are a type of natural disaster.

However, tropical cyclones are also part of the atmospheric cycle, which can carry heat energy and angular momentum of the Earth's rotation from the equator to higher latitudes. In addition, it can also bring abundant rain to coastal areas that have been dry for a long time.

The sea surface is very hot by the sun, a large amount of water vapor evaporates, rises and gathers in the sky, condenses in the sky and emits a lot of heat, heat as energy, under the action of the geostrophic deflection force, pushes the entire large cloud of water vapor to rotate, and then more water vapor evaporates, condenses and dissipates heat, the rotation is faster and faster, the heat continues to push the rotation and movement, the air flow in the central area is thrown around in the process of rotation, the air flow is getting less and less, and the air pressure is getting lower and lower. Eventually, a tropical cyclone formed and began to move, and it was a typhoon.

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.

Broadly speaking, the term "typhoon" is not a tropical cyclone intensity. Tropical cyclones (including tropical storms, severe tropical storms and typhoons as defined by the World Meteorological Organization) with sustained winds of metres per second or more at their centre are referred to as typhoons. Officially, the term "typhoon" even refers directly to the tropical cyclone itself.

When a tropical cyclone in the northwest Pacific reaches the intensity of a tropical storm, the names are provided by the 14 countries and territories of the Typhoon Committee of the World Meteorological Organization.

Characteristics of tropical cyclones

Tropical cyclones include tropical depressions, tropical storms, severe tropical storms, and typhoons. Therefore, tropical cyclone disasters also include disasters caused by tropical depressions, tropical storms, severe tropical storms, typhoons, etc.

The characteristics of tropical cyclone disasters are related to their life history, structure and activity patterns. The process of tropical cyclones from the initial formation of low pressure to the extinction or transformation into extratropical cyclones is usually divided into the formation period, the development period, the maturity stage and the decline period. The general duration of the entire life history is 3 8 days, the longest can be more than 20 days, and the shortest is only 1 2 days.

Generally, tropical cyclones have a longer lifetime in summer and autumn, while they have a shorter life span in winter and spring.

A tropical cyclone is a low-pressure vortex that occurs over a tropical or subtropical ocean, and is a powerful and deep "tropical weather system". It is a classification of tropical cyclones in countries or regions north of the equator and west of the date line.

A typhoon is a deep system of depression with a very low central pressure, with significant convergence towards the center in the lower layers and major outward divergence in the top. If you cut the typhoon horizontally, you can see that there are three distinct areas, from the center to the outward: the typhoon eye area, the cloud wall area, and the spiral rain belt area.

Typhoon Eye Area: Very peculiar, where the wind is very small, the weather is clear, the average diameter is 40 kilometers, and the seafarers who are present in it humorously call the typhoon eye the "paradise sock ruler source" of the typhoon.

Cloud wall area: The cloud wall area around the eye of the typhoon is dozens of kilometers wide and more than ten kilometers high, also known as the eyewall. Here the cloud walls are towering, the wind is howling, the rain is pouring down, the sea is churning, and the weather is at its worst.

Spiral rain belt area: outside the cloud wall is the draft fiber spiral rain belt, there are several rain (cloud) belts in a spiral shape to the eye wall around the convergence, the rain bandwidth is tens of kilometers to hundreds of kilometers, thousands of kilometers long, the rain belt will fall showers where it passes, and there will be windy weather.

A tropical cyclone typhoon is an atmospheric vortex that forms over the tropical ocean east of the Philippines. It can be generated all year round, with the most months in summer and autumn.
