The cause of the storm

Question 1: How did the storm form? A storm is a wind with a wind force of 1 1.

A typhoon has six brothers.

Super typhoon (super typhoon)

The maximum average wind speed near the bottom center is ≥ 5 1.0m/s, that is, 16 or more.

violent typhoon

The maximum average wind speed near the bottom center is 41.5-50.9m/s, which is 14- 15.

The third typhoon (ty)

The maximum average wind speed near the bottom center is 32.7-4 1.4m/s, which is 12- 13.

No.4 strong tropical storm (STS)

The maximum average wind speed near the bottom center is 24.5-32.6m/s, that is, the wind force is10-1.

Tropical storm in Laowu (TS)

The maximum average wind speed near the center of the ground floor is 17.2-24.4m/s, that is, the wind force is 8-9.

Laoliu tropical depression

The maximum average wind speed near the center of the ground floor is10.8-17.1m/s, that is, the wind force is 6-7.

So the storm was brought by Lao Si. So the question becomes how typhoons are formed.

In tropical or subtropical oceans where the sea surface temperature exceeds 26℃, due to the high temperature near the ocean surface, a large amount of air expands and rises, which reduces the air pressure near the ocean surface, and the peripheral air continuously flows in and rises. Affected by the geostrophic force, the inflowing air rotates. The rising air expands and cools, and when the water vapor in it cools and condenses into water droplets, it will release heat and promote the rising of the lower air. In this way, the air pressure near the ocean surface drops lower, and the air rotates more violently, eventually forming a typhoon.

I hope it helps you.

Question 2: How did the storm form? Desert storm is a natural phenomenon that often appears in the desert. It can be divided into sandstorms and tornadoes.

The wind is strong in desert areas, and storms blow up dust, which falls like conservation. This is called a sandstorm. The sandstorm came, the wind roared, and Sha Fei was everywhere. The storm covered the sky with fine waste sand and turned the clear sky into night in a twinkling. After the sandstorm, trees were uprooted, crops dried up due to dehydration, and the countryside became desolate. It can be seen that sandstorm is a natural phenomenon and has great destructive effect. But in the desert, there are not many opportunities for big sandstorms, so it is also a unique scenery in the desert area. Mud safety pens, desert tornadoes are very common. Because it appeared in the arid desert area, it became a dry tornado. Tornado is a phenomenon that the air near the ground rotates and rises after being strongly heated. Tornadoes roll the dust on the ground into the air for tens or even hundreds of meters, forming a rotating dust column. On the Gobi Desert in China, we can often see dozens or even hundreds of tornadoes appear at the same time. These buildings with a diameter of 10 meters and a height of 100 meters rotate clockwise or counterclockwise, and the whole Gobi becomes a natural dance floor, which is spectacular.

Meteorologists say that the low-pressure system generated and developed on the surface of tropical ocean is called tropical cyclone. Internationally, the intensity is determined and classified by the maximum wind force near its center: typhoons with magnitude above 12 are generally called typhoons; 10 ~ 1 1 is a strong tropical storm; Grade 8 ~ 9 is a tropical storm; Less than 8 is tropical depression.

A typhoon is a cyclone that occurs in the tropical ocean. If a weak tropical cyclone system is generated or moved on the surface of the warm tropical ocean with high water temperature, in a suitable environment, due to friction, the airflow will produce a component that flows into the weak vortex, bringing a large amount of water vapor evaporated from the surface of the high-temperature ocean to the inside of the vortex, gathering high-temperature and high-humidity air to the center of the weak vortex, generating ascending and convective movements, releasing latent heat to heat the air column above the center of the vortex, and forming a warm heart. As the vortex center warms, the air becomes lighter, the central air pressure drops and the vortex becomes stronger. When the vortex becomes stronger, on the other hand, the warm and humid air in the lower layer converges inward more strongly, more water vapor is concentrated to the center, convection is more vigorous, the center gets warmer, and the central air pressure drops more, and so on until it becomes a typhoon.

How are micro storms formed?

1982 One day in early summer, a Pan Am airliner took off from New Orleans International Airport. Shortly after take-off, the plane suddenly bumped violently and then descended rapidly. With a loud explosion, all the crew and passengers of 153 were killed.

The National Transportation Bureau of the United States quickly investigated the tragedy of the air crash that shocked the world, but could not find the reason. It was only found that there was a mysterious force controlling the plane at that time, which made it difficult for the pilot to deal with it.

According to records, this mysterious force has caused more than 30 vicious accidents at airports all over the United States.

A few years later, meteorologists revealed the truth of the case. They confirmed through field tests that the chief culprit of these air crashes is a meteorological phenomenon that people are not familiar with-micro-storm.

Micro-storms, also known as mini-storms, are tiny vertical downward flow, lasting only 65,438+00-20 minutes. The affected area is only 3-4 kilometers in diameter and only a few hundred meters in size. But in its area, the wind direction and wind speed are extremely complicated. At the two ends of the micro-storm center, the direction of the wind will be completely opposite, and sometimes it can mutate repeatedly, which is called "wind shear" in meteorology.

At present, the formation principle of micro-storms has not been fully understood. Most scientists believe that it is caused by the evaporation of raindrops. When raindrops evaporate, part of the air will become cold and heavy and fall, resulting in downward flow.

Question 3: What is the green shadow in the storm video? When watching the video, people and subtitles will be haunted! The reason is the problem of video format and file and the problem of original video compression! Your version of Storm Video is too new and the video decoding is too strong! If you want to watch this video without green bars, you can install a realplay version 10 player, and then use RealPlay to play this video without green bars! Just install an extra player, which is more troublesome and won't be used often!

Question 4: What happened to the advertisement of Beauty Studio in Storm Video?

Question 5: What's wrong with computer storm video? This happens because users open some advertisement blocking software (such as "ADSafe Master") when using Storm Video. Because these advertisement blocking softwares (including ADSafe3) are often turned on by default to ensure the filtering effect, users will "unconsciously" encounter the error code of 3 1000 when they open Storm Video again.

Solution: First close Storm Video, then quit the advertisement blocking software (please note that it is not closed, but completely quit), and then restart Storm Video.

In addition, it is suggested that before restarting the storm video, it is best to thoroughly clean the computer with 360 security guards and other software before starting the storm.

Question 6: There are two pictures when the storm video is played. What happened? There are two playback windows before and after using nbsp storm video, because and nbsp are installed in the system. Storm video is not compatible. DVDnbsp decoder, and its priority is higher than that in storm video. Decoder, you need to use the filter management of nbsp storm video nbsp to disable the original nbsp. DVDnbsp decoder or use nbsp. GSpotnbsp。 Reduce its nbsp. advantage
