About 1 hour after the alarm was issued, citizens near Yundonghai Street in Sanshui District took a live video picture of tornado attacks.

At 16:40 pm, the meteorological department confirmed the suspected tornado in Yundonghai Street, Sanshui District. Since July 2nd, the meteorological department has released many tornado alarm. Especially at 8-17 on July 2nd, when the meteorological department issued 6 typhoon news and heavy rain warning signals, the forecast bureau had a tornado. This is the most accurate of the tornado alerts issued by the Foshan Meteorological Department on July 2nd.

Data show that since 2006, strong wind disasters caused by tornado and thunderstorms have caused 45 people in Foshan to be killed and 446 people were injured. Foshan tornado average of nearly 1.5 years (the average annual province is 4.3). From 2006 to 2021, there were 23 tornado in Foshan, and so far, it has reached 27.

The Meteorological Department of Guangzhou Municipal Meteorological Department:

The tornado destruction of Huangpu District is 20 seconds of no one casualties

On the morning of July 4, the Guangzhou Meteorological Bureau, Foshan Tornado Research Center and Huangpu District Meteorological Bureau sent experts to Nangang Street to conduct field investigations to obtain videos, photo materials and other methods by inspecting the disaster destruction of the disaster, visiting the tornado witnesses. At the same time, the analysis of meteorological observation data believes that this tornado is initially graded EF0, which was touched at 7:8:00 on July 4, 2022, disappeared at 7:10, and the history of the tornado life was about 2 minutes. The influence is about 160 meters and the path affects about 1.1 kilometers.

Why are there more in Guangdong's tornado recently?

Recently, Chaozhou, Shantou, Foshan, and Huangpu District of Guangzhou

There are tornado,

Why do you have more tornado recently?

This is related to the typhoon "Siaba" that landed in Guangdong on July 2

Typhoon "Siaba" induced multiple tornado before and after landing:

June 30: Around 16:47, there was a weak tornado near Danqiu Village, Yanfeng Community, Shishan Town, Nanhai District, Foshan

July 2nd:

At around 7 o'clock, there was a tornado in Futuyang Town, Chao'an District, Chaozhou, with a length of about 1 km in length;

Around 10:30, water tornado appeared on the sea surface of Shantou South Australia;

At around 17:30, tornado appeared in Xiqiao Town, Nanhai, Foshan.

July 4:

Around 7:10, tornado appeared near No. 111, Kangnan Road, Huangpu District, Huangpu District, Guangzhou.

Why do you have more tornado recently?

Experts from the Guangzhou Meteorological Department said: Recently, it has entered the season of strong convective weather. The probability of thunderstorms, hail, and tornado has a relatively high probability. At the same time, the typhoon "Siaba" landed in Guangdong, which is easy to stimulate the tornado.

The wind speed of the typhoon itself is very large, and it is easier to form vertical wind cutting that is conducive to miniature super monomers and tornado. On the rain belt of the typhoon, miniature super monomers are often generated, and some can cause tornado. According to Li Caoling, deputy director of the Foshan Meteorological Observatory, tornado is generally divided into two categories: west wind rolls and typhoon tornado. For the South China region, the western wind tornado mainly appears in the previous flood season. For example, during the "Dragon Boat Water" period in the previous paragraph, Conghua and Foshan appeared in Guangzhou. Typhoon tornado is that when the typhoon moves north and northwest, there are many miniature super monomers in the scope of the spiral rain belt, which can easily lead to the appearance of the tornado.

Meteorological Bureau: China belongs to many countries in tornado, and now it is more likely to be seen and recorded

According to the Guangzhou Meteorological Bureau, tornado is a small -scale strong stream of disaster weather. It has strong locality and suddenness, often accompanied by strong convective weather systems such as thunderstorms, hail and rainstorm.

China belongs to many countries in tornado. Tornado is not uncommon. Due to terrain, tornado is generally short and weak. Due to the limited observation methods, it is still difficult to monitor the actual wind speed and central air pressure and other meteorological elements of the tornado. The conventional meteorological observation station can rarely observe the existence of tornado. Estimation value of survey or radar observation.

Witnesses and investigations related to tornado were not as fast as it is now. Tornado occurred but may not be recorded. With the development of urbanization, smartphones and the Internet, more tornado has been seen and recorded.

The average annual tornado in my country, Jiangsu and Guangdong the most

According to reports, global tornado occurs mainly in the middle latitude, among which the United States is the country with the most tornado. Most of the provinces (autonomous regions and municipalities) in my country have tornado traces, and tornado mainly occurs in the eastern plains of China.

In the past 30 years (1991-2020), there are an average of 38 in my country each year, of which Jiangsu and Guangdong have the most. Spring and summer are the season of tornado, and the number of tornadoes in April-August accounted for 92%of the year.

According to incomplete statistics, Guangzhou has recorded a total of 22 tornado (including water tornado) since 2000, and the number of tornadoes in April-August accounted for 81.8%, of which Huadu District, Nansha District and Huangpu District were recorded. The number of tornadies is the most, 5, 4, and 4, respectively.

save to! How to avoid rolling wind?

These knowledge is useful

To define the tornado strength,

According to Fujita level, it can be divided into 6 levels of EF0-EF5.

Wind speed is usually 30-100 meters per second,

The maximum wind speed of the center can exceed 140 meters per second,

In practice, the tornado above EF2 is called a strong tornado.

The current tornado level division ↓

remind:

It is expected that due to the "Siaba" residual circulation and the joint influence of the southwest monsoon, Guangzhou will still be as heavy as heavy rain on the 5th to 7th. Wait for the strong convection weather; after the 8th, the deputy high will strengthen the west extension, and Guangzhou will turn high temperature and hot weather.

At present, Guangzhou is in a period of strong convection. In the next few days, the weather is unstable. It is necessary to continue to do strong precipitation, short -term wind, lightning, and local tornado.
