Tornado is not uncommon in my country

Internet development makes it more visible

Recently, there have been tornado weather in Guangdong. At around 20:00 on June 16, a tornado occurred in Taiping Town, Conghua District, Guangzhou. On June 19th, June 30th, and July 2nd, three tornado appeared in the Nanhai District of Foshan. On the morning of July 2, a weak tornado occurred in Chao'an District, Chaozhou, and water tornado appeared near Nan'ao Island, Shantou. On July 4, tornado appeared in Huangpu District, Huadu District, and Foshan.

What causes the tornado? The Guangzhou Municipal Meteorological Bureau took the situation of Guangzhou as an example. The tornado weather occurred in Huangpu Nangang on July 4, or it was related to the typhoon "Siaba", because the tornado -related strong convection was "Siaba". According to incomplete statistics, Guangzhou has recorded a total of 22 tornado (including water tornado) since 2000. Among them, the number of tornadies that occurred from April to August accounted for 81.8%. The number of tornadies to the most, 5, 4, and 4, respectively. According to reports, from a global perspective, tornado occurs mainly in the middle latitude region. Among them, the United States is the country with the most tornado. In our country, tornado occurs mainly in the eastern plain, but most provinces (autonomous regions, cities) have recorded the trails of tornado. In the past 30 years (1991-2020), the average of 38 tornado is generated every year in my country, of which Jiangsu and Guangdong are the most.

Is the climate changed frequently? The interpretation of the Guangzhou Meteorological Bureau believes that in fact, the tornado is not uncommon in my country, but due to terrain, the tornado that occurs in my country is generally short and weak in strength. Due to the limited observation methods, the conventional meteorological observation station rarely observes the existence of tornado. However, with the development of urbanization, smartphones, and the Internet, more tornado is seen and recorded, and to a certain extent, the probability and intensity judgment accuracy of the tornado is recorded.

The Guangzhou Municipal Meteorological Bureau also analyzed that due to the "Siaba" residual circulation and southwest monsoon, it is expected that there will still be heavy rains in Guangzhou from July 5th to 7th, and some time will be large. Grade gusts, lightning, local tornado and other strong convection weather.

The Meteorological Bureau reminds the public that it is currently in the period of strong convective weather. It is necessary to do a good job of strong precipitation, short -term wind, lightning, and local tornado.
