The neighbor's roof was torn by strong winds
Ms. Hu, who lives in Xiaohai Town, Dafeng District, said, "On the afternoon of August 13th, there was a lot of wind and rain. Later, when I saw a tornado carrying a burst of sand and dust, it rolled over."
A merchant in Longgang Village, Dafeng District told the Beijing Youth Daily reporter that around 4 pm on August 13th, a strong gust of wind came from outside the window. "I could hear a loud noise, so I immediately hid at home. As soon as the wind passed, some neighbors' roofs were torn by the strong wind."
A merchant who sells electric vehicles in Kangning Village, Dafeng District, recalled that at around 3pm on August 13th, he first saw a clear darkening of the northern sky, and then heard a loud wind. "There was a rumbling sound, much louder than the usual windy sound. Before it rained, there were also groups of dragonflies flying over," he said
Afterwards, the merchant and their family returned home to take refuge. "There was a lot of wind and rain outside, and the black tornado was moving from northeast to southwest, looking several hundred meters high, which I had never seen before. The tornado was very fast and lasted for about ten minutes."

Jiangsu and Guangdong have relatively more occurrences
Experts from the Institute of Atmospheric Physics of the Chinese Academy of Sciences introduced to the reporter of the Beijing Youth Daily that there is still some controversy about the cause of tornadoes in the academic community, but it is generally believed that strong wind shear may occur in severe convective weather, and the horizontal vortex formed is converted into a vertical vortex, thus forming a tornado.
Experts say that tornadoes often occur in areas such as the Great Plains, and can also occur in East China. "Tornadoes have a relatively small spatial scale and strong suddenness. They occur quickly and have a low probability of occurring in our country, making it difficult to predict and predict them."
On August 14th, China Weather Network released an article introducing that tornado intensity is divided into six levels: EF0 to EF5, with EF0 being the lowest and EF5 being the highest. The tornado that occurred in Yancheng, Jiangsu is at EF2 level. EF2 level and above tornadoes are generally referred to as strong tornadoes, and EF2 level tornadoes can cause significant damage, potentially causing trees to be uprooted.
The article states that there are traces of tornadoes in most parts of China, with the middle and lower reaches of the Yangtze River being the most frequent areas. According to statistics from the National Climate Center from 1991 to 2020, Jiangsu, Guangdong, Hubei, Anhui and other provinces in China have a higher number of tornadoes, with Jiangsu and Guangdong having the highest number, with an average annual number of tornadoes of 4.8 and 4.3, respectively.
