Why do typhoons make landfall at night????

It is correct that there will be typhoons during the day and night, but sometimes typhoons come at night because the temperature difference between the land at night and during the day is large, and the specific liquid solution of seawater is small. A sea and land breeze is formed, which blows from the sea to the land.

China classifies tropical cyclones in the South China Sea and the Northwest Pacific into six categories based on their maximum average wind speed near the center of the bottom layer, of which wind force 12 or above are collectively referred to as typhoons.

According to the U.S. Navy's Joint Typhoon Warning Center, the number of typhoons in the Northwest Pacific and the South China Sea between 1959 and 2004 was related to the month, with an average of one typhoon per year, with the most typhoons occurring in August of the Gregorian calendar, followed by July and September.

The timing of typhoon landfall has nothing to do with day or night, and it has nothing to do with the ebb and flow of the tide. However, it is true that there will be big waves when a typhoon landfalls.

The time of typhoon landfall has nothing to do with day and night, and it has nothing to do with the ebb and flow of the tide.

Today"Pearls"Probably just land in the afternoon.

The typhoon during the day is cool, like today, and you don't have to go to school all day.

Typhoon landfall has nothing to do with day or night.

It is correct to say that there will be typhoons day and night, and according to statistics, there are indeed more typhoon landfalls at night and less during the day, but there is not much difference. In fact, in terms of data analysis, there is no obvious pattern of typhoons making landfall during the day or at night, but there are some differences in the number of typhoons. There could be two reasons why the typhoon made landfall at night.

1. The landfall of typhoons is affected by the phenomenon of "sea and land breeze". Affected by the sun's irradiation, the sea and land temperature changes differently, and the coastal areas generally blow to the sea breeze during the day and the shore wind at night.

The sea and land breeze is a diurnal wind system that forms near the coast due to uneven heating between the sea and the land. When the basic airflow is weak, the wind blows from the sea to the land during the day and from the land to the sea at night. The former is called the sea breeze, and the latter is called the land breeze, which is collectively known as the sea and land breeze.

Since the difference in low-altitude heat at night is much less than that during the day, the land breeze circulation is weaker than the sea breeze circulation, regardless of the air velocity or circulation height, and the wind speed of the land breeze is only 1 2 m s. The sea and land breezes are strongest in the tropics and can occur all year round, more often than in temperate and cold zones. In the mid-latitudes, such as the Bohai Sea region of China, the sea and land breezes occur more frequently in summer and autumn than in winter and spring.

Larger islands, such as China's Hainan Island, can also experience land and sea breezes. The sea breeze blows from all sides to the island during the day and the land breeze blows from the island to the surrounding sea at night.

I can see that although the land and sea breeze phenomenon exists, the impact is not very large, and it may be that the number of typhoons making landfall at night is only a little higher than during the day.

2. The influence of people's psychological factors.

Human beings have an innate fear of the night, and the memory of the destruction in the night will be clearer, and the contrast of the next day after the typhoon landslides is too great, it is possible that because of these circumstances, people have a clearer impression of the typhoon that lands at night, but the impression of the typhoon that makes landfall during the day is not very deep.

Typhoon landfall means "the center of the typhoon moves to land as a whole", that is, the place where the center of the typhoon makes landfall is said to be "the wind in Taiwan and the government makes landfall somewhere".

Because typhoons do not necessarily have such dry typhoon eyes, it is inaccurate to say that the eye of the typhoon reaches land.

Typhoons are a type of tropical cyclone. A tropical cyclone is a low-pressure vortex that occurs over a tropical or subtropical oceanic forest, and is a powerful and deep "tropical weather system". China divides tropical cyclones in the South China Sea and the Northwest Pacific into six categories according to the magnitude of the maximum average wind force (wind speed) near the center of the bottom layer, of which the wind force near the center is 12 or above, collectively referred to as typhoons.

Hello dear, <>

<>I am the main Q&A of the year's celebration Mr. Yang: On the 7th of the month, Typhoon "Ewini" made landfall in the coastal area of Taishan, Jiangmen City, Guangdong Province, with a central wind force of 12 at the time of landfall. On the 10th, Typhoon "Dandelion" made landfall in the coastal area of Houmen Town, Haifeng County, Shanwei City, Guangdong Province, with a central wind force of 12 at the time of landfall.

On the 17th, Typhoon "Chaba" made landfall in the coastal area of Fangcheng District, Fangchenggang City, Guangxi Zhuang Autonomous Region, with a central wind force of 14 at the time of landfall. On the 20th, Typhoon "Sango" officially "made landfall" over the northwest Pacific Ocean, with a central wind force of 11 at the time of landfall. On January 1, Typhoon "Lubi" made landfall in the coastal area of Youjiang District, Baise City, Guangxi Zhuang Autonomous Region, with a central wind force of 12 at the time of landfall.

On the 10th, Typhoon "Kangsen" made landfall in the coastal area of Taitung County, Taiwan Province, with a central wind force of 12 at the time of landfall. On June 1, Typhoon "Sanda" formed over the northwest Pacific Ocean and gradually approached the northeastern coast of Taiwan Province, and made landfall in the coastal area of Fuqing City, Fujian Province on June 3, with a central wind force of 12 at the time of landfall. On July 28, Typhoon Xuanlanuo formed over the ocean east of Japan and gradually approached the northeastern coast of Luzon Island in the Philippines, and made landfall in the coastal area of Dapeng New District, Shenzhen, Quang Dong Province on July 30, with a central wind force of 12 at the time of landfall.

A typhoon landfall is when the center of the typhoon moves over land as a whole. The so-called typhoon center is generally the typhoon eye, so that is to say, when the trajectory of the typhoon eye intersects with the coastline, the typhoon makes landfall, and the intersection of this center point and the coastline is the landing point.

The landing site of a typhoon does not necessarily mean that it is the most severely affected place. The reason for this is mainly due to the fact that the typhoon caused damage to a place in Xinpei, mainly through the strong winds, heavy rains and storm surges it brings. It is difficult to judge the specific impact of the typhoon from the landing site alone, and it is necessary to combine the changes in the structure before and after the typhoon's landfall, the coordination of the weather system, and the different topography of the landing site to analyze the specific impact of the typhoon.

Typhoons can cause flooding. After the landfall of Zhengfeng "Fit" in Taidayin, Yuyao and other places suffered serious internal waterlogging, and many streets were waist-deep, exceeding 1 meter. Some primary and secondary schools have been forced to close.

Typhoons can drown out crowds. Typhoon-swept areas can cause damage to homes, and people who don't have time to flee may be injured, drowned, or electrocuted.

Typhoons can destroy buildings. Typhoons will not only destroy fragile buildings, but also destroy crops, drown some farming cattle, and leave homes without fields and even animals at home.

Typhoons can affect flights. During a typhoon, some flights may be forced to stop Chi Song, and some flights that are already on the road may be attacked.

The landfall of a typhoon will endanger national interests and, even more, the lives of the broad masses of people.

Storms and storms at sea will capsize.
