Will typhoons be small where there are mountains? Will a typhoon weaken when it encounters a mountai

Where there are mountains, the wind may be less windy, but that doesn't mean the typhoon will be smaller.

A typhoon is a strong tropical cyclone that usually forms over tropical oceans. They often bring extreme weather such as strong winds, torrential rains, and flooding. Although the mountain range may have a certain hindering and weakening effect on the typhoon's wind, this does not mean that the typhoon will become smaller or weaker.

In fact, the impact of mountains on typhoons is complex. On the one hand, mountain ranges can obstruct the typhoon's path, slowing it down or stagnating, reducing its wind strength. On the other hand, mountain ranges may cause typhoons to produce stronger winds and precipitation because they cause aircurrents to fluctuate in typhoons, increasing their energy and intensity.

In addition, the intensity and magnitude of a typhoon also depend on the environmental conditions at which it formed and its own structure. Even where there are mountains, typhoons can still form and intensify if the environmental conditions are suitable.

Therefore, although mountains may have a certain effect on the wind strength of a typhoon, it cannot simply be assumed that a typhoon will become smaller where there are mountains. In the face of typhoons, people still need to take the necessary precautions to protect themselves and their property.

Where there are mountains, the typhoon will definitely become a little smaller.

Typhoon landfall will be affected by the terrain, and if there are obstacles on the ground, its wind power may be hindered to a certain extent.

Therefore, the destructive power of typhoons should be reduced, so where there are mountains, the wind power of typhoons will decrease, and the destructive power will gradually weaken.

Basically, where there are mountains, when a typhoon passes by, it is blocked, and the wind becomes weaker.

The areas least affected by typhoons are in the middle and high latitudes, near the equator, and in the tropical subtropics.

of the west coast of the continent and other regions.

1. Middle and high latitudes.

In the middle and high latitudes, it is impossible to form a typhoon. Because the solar radiation income in the middle and high latitudes is low, the sea temperature is low, and the required water temperature of 26 degrees cannot be reached. (Typhoons form over vast oceans with a sea surface temperature of 26 degrees or higher in the tropics and subtropics, and are tropical cyclones that develop strongly.)

2. Near the equator.

Typhoons cannot be formed in the sea area near the equator, because there is no geostrophic deflection force at the equator, and the geostrophic deflection force near the equator is very small, so it is impossible to form a vortex wind and rain area in the typhoon structure, let alone a unique typhoon eye area.

3. The west coast of the subtropical continent and other regions.

The probability of typhoons on the west coast of the tropics and subtropics is also small, because cold currents generally pass over the west coast of the continent in the tropics and subtropics (such as North Africa).

The Canary Cold Snap on the West Coast, the Benguela Cold Snap on the West Coast of South Africa, the California Cold Snap on the southwest coast of North America, the Peruvian Cold Snap on the West Coast of South America, the Western Australian Cold Snap on the West Coast of Australia, etc.), the cold snap plays a role in cooling and dehumidifying, and the general sea temperature is difficult to reach 26 degrees.

When a typhoon is coming, the wind speed at the top of the mountain is usually greater than the wind speed below.

First of all, the wind speed of a typhoon usually increases with the height above the ground. This is due to the influence of ground roughness and temperature gradient on typhoon or air flow, which causes it to be rubbed by obstacles when approaching the ground, which consumes part of the kinetic energy and gradually reduces the wind speed.

Secondly, if the terrain is a canyon, then the wind will be stronger under the mountain than on the mountain. This is because at the base of the mountain, the wind is less obstructed, so the wind is stronger. On the other hand, due to the high altitude, the air pressure is low, and the corresponding wind is also stronger.

In summary, when a typhoon comes, the wind speed at the top of the mountain is usually greater than the wind speed at the bottom of the mountain, especially in mountainous areas with complex terrain. However, this does not mean that the wind under the mountain is necessarily small, because the wind strength may also be affected by various factors such as surrounding terrain, air pressure, and obstacles.

Looking at the terrain, if it is a canyon, then the wind under the mountain is definitely greater than that on the mountain (provided that the altitude of the mountain is not much different).

In general, due to the high altitude of the summit and the low air pressure, the corresponding wind is stronger.

Since the Northern Hemisphere cyclone rotates counterclockwise, the wind direction is different before and after the typhoon center passes, so the magnitude of the wind depends on the terrain around it. The Fuding tragedy caused by Sangmei in 2006 was due to the above reasons. (Fuding Dapi is high in the north and low in the south, and the wind will blow back after the wind is blocked by the mountain).

Hello, I am a life expert pig spirit netizen, good at answering life questions, I am very happy for your question. When a typhoon approaches a mountain range, the mountain block the flow of air currents and force the air to rise. This upward air flow causes water vapor to condense into clouds, forming precipitation.

As a result, typhoons usually bring a lot of precipitation above the mountains. In addition to this shelter, the mountains will also weaken the typhoon's winds. When the air flow of a typhoon is blocked by a mountain range, a topographic blocking effect occurs, causing the wind speed of the typhoon to weaken.

The height and shape of the mountains affect the extent of this effect. However, it is important to note that typhoons may re-intensify after passing through the mountains. When a typhoon passes through a mountain range, it may regain its strength and continue to move forward if it re-enters a more open ocean or plain area.

In general, mountain ranges have some influence on the path and intensity of a typhoon, but the exact extent of the impact depends on the height and shape of the mountain range and the characteristics of the typhoon itself. Above, I hope to be able to answer your questions, and if you have more life questions in the future, please write to me to ask questions.

There are two reasons why a typhoon can be blocked by mountains:

1.Mountains can obstruct a typhoon's path, slowing it down or stalling, reducing its wind power.

2.Mountains can cause stronger winds and precipitation in typhoons, as they cause airflow to fluctuate during a typhoon, increasing the energy and intensity of the sedan car.

In short, typhoons are blocked by mountain ranges because they have the effect of blocking, circling, and friction against the typhoon, which may affect the typhoon's path, speed, and intensity.

Thermal energy, typhoon is a huge central warm-hearted cyclone, after the typhoon landfalls, due to the surface friction of the use of acres and squeezing will make the structure of the Taiwan reform and wind break rapidly, friction will produce heat energy.

At around 10:50 today (August 10), Typhoon "Mulan", the No. 7 typhoon in Zhoushan this year, landed in Xuwen, Guangdong. Affected by it, there are obvious wind and rain weather in Guangdong, Hainan and Guangxi today, which may trigger heavy rainfall locally, and it is necessary to be vigilant against the occurrence of secondary disasters such as geological disasters and floods in small and medium-sized rivers.

At the time of landfall, the maximum wind near the center of "Mulan" was 23 meters per second, level 9, and the minimum pressure at the center was 992 hPa, and the intensity was tropical storm. It is expected that "Mulan" will continue to move west-northward at a speed of 20 kilometers per hour, and enter the Beibu Gulf on the afternoon of the 10th, gradually weakening in intensity.

This year's No. 7 typhoon "Mulan" formed yesterday, due to the influence of its outer circulation, in the past day, heavy to heavy rain occurred in parts of southern Guangdong, western and northern Hainan Island, and local heavy rain in Yangjiang, Jiangmen, Zhuhai, Zhongshan and Shenzhen in Guangdong; Gusts of 8 9 occurred along the coast of Guangdong, the northeastern coast of Hainan Island, and the Dongsha and Xisha Islands, with local gusts of 10 and 11.

Zhanjiang Maritime Safety Administration reported that due to the impact of "Mulan", the passenger ro-ro transport route in the Qiongzhou Strait was suspended from 17 o'clock on the 9th. In addition, the Guangdong Zhuhai Port Bureau issued a notice today saying that the Lotus Bridge will be closed, and the Hengqin Port will suspend the entry and exit procedures for passengers from this morning.

**The Meteorological Observatory predicts that under the influence of the outer circulation of Typhoon "Mulan", the South China coast will be heavy and rainy, and there will be heavy rain or torrential rain in parts of Guangdong, Hainan Island, central and southern Guangxi, and southern Yunnan in three days from today, and there will be heavy rain locally; There will be 6 7 level winds in the central and northern parts of the South China Sea, the Beibu Gulf, and the Qiongzhou Strait, of which the wind rise force in the nearby waters where the typhoon center passes can reach 8 9 and 10 11 gusts. From the perspective of the rainfall process, today is the strongest period of rainfall, and the rainfall in the above areas will weaken significantly from tomorrow, and the local area needs to pay attention to the possibility of local geological disasters, floods in small and medium-sized rivers, waterlogging and other disasters.

Typhoons often bring a lot of precipitation, and the mountainous terrain is steep, and the water flow is turbulent, which is often prone to geological disasters such as mudslides and landslides, and the destructive impact is of course more extensive.

2.In hilly and mountainous areas, the river system is generally short and rapid, and the drainage is good. And some valleys with lakes are not very well drained.

Pay attention to people's lives in the world's most hope is happiness and peace, but sometimes natural and man-made disasters are unavoidable, such as typhoons are the topic we have been paying attention to, many people have lost their lives because of typhoons, do you know what terrible typhoons have been there so far? Let's take a look.

10. Nora.

It happened decades ago, and the protective measures at that time were not as good as they are now, and a typhoon killed 18 people and made people's hearts ache.

9, Taipei. It was a particularly strong tropical cyclone, which almost broke the typhoon record, and even caused more than 40 deaths, and also caused flooding because of the typhoon.

8, John. It doesn't cause much to people, but it involves a wide range and lasts for a long time, about more than 30 days in total.

7. Forrest.

The sandstorm was particularly rapid, with heavy rainfall, putting the entire country of Japan in danger and killing more than 20 people.

Recently, Japan has been hit by a number of super typhoons, causing huge losses to the local area, but also attracting international attention, typhoons are actually a kind of tropical cyclones, the wind force is more than 12, the center of the continuous wind speed of more than meters, can set off huge waves, causing storms.

Typhoons are a very destructive and severe weather system.

"Water is the source of life", nourishing all things and nourishing living beings, and human beings have never stopped pursuing water. The world's four ancient civilizations all prospered because of water.

Typhoons are terrifying natural disasters that can destroy buildings.

The most terrible thing about typhoons is that they are collateral disasters, the damage can be repaired, and lives cannot be lost or reversed. But don't lose faith and hope that the disaster area will cheer up!

In addition to the typhoon itself, the subsequent weather disasters caused by the typhoon will greatly endanger the safety of people's lives and property.

Personally, I think that typhoons have multiple effects.

Precipitation, inundation of road sections, causing economic losses, damaging houses, threatening life safety, and also has an adverse impact on urban greening construction.

The good thing is that it can cool down and remove dust, which is conducive to purifying the air.

It can cause severe natural disasters and destroy people's property.

The most terrifying thing should be irresistible!

Serious disasters such as storms are brought to the landfall area.

In less than a month since late July, after Typhoon "Appi" and "Skylark", East China has ushered in a third typhoon.

From the beginning of July to the beginning of August, the subtropical high "covers" over North China, Northeast China, Huanghuai and other places like a pot lid, and the coastal areas of East China are on its southern edge. "Typhoons 'Appi' and 'Skylark' were both affected by this, and it can be said that they 'climbed' along the southern edge of the subtropical high to East China. At present, the subtropical high is moving westward close to the mainland of China, and the east coast of China is still on the southern edge.

Because of this, the landfall site of Typhoon Capricorn is also in Zhejiang. ”

This year, the subtropical high is strong and northerly, so the subtropical high is prone to high temperature weather in the subtropical high control area. On the north side of the subtropical high, the cold air is relatively weak, and at the same time, the warm and moist airflow continuously transported from the west side of the subtropical high meets the cold air on the north side, providing good conditions for rainfall. ** Fang Chong, chief forecaster of the Meteorological Observatory, said.

Coastal areas, especially the southeastern coastal provinces and cities.

The explanation is as follows.

Guangdong is the most preferred area for typhoons in China.

According to statistics, from the beginning of 1949 to August this year, a total of 166 typhoons made direct landfall on the coast of Guangdong, an average of 2 to 3 per year, far exceeding other provinces.
