Were there tornadoes in modern China?

Most provinces (autonomous regions and municipalities) in China have tornadoes, mainly distributed in the eastern plain, 199 1 to 20 14. There are 43 tornadoes on average in China, with Jiangsu and Guangdong being the most, with an average of 5.5 and 4.8 tornadoes each year. Spring and summer are the frequent seasons of tornadoes, and tornadoes account for 92% of the whole year from April to August.

At about 2: 30 pm on June 24, 2020, a huge cyclone occurred in Xilinhot, Inner Mongolia. Huge wind columns connect heaven and earth, and the airflow and clouds formed by violent cyclones are constantly distorted, which is like a magical blockbuster under the dark thunderstorm clouds.

On June 2, 2020, at about 0/4 o'clock, Gaoyou City, Jiangsu Province was hit by a tornado. In three villages affected by the tornado, Wang Qin Village, Guanhuo Village and Haozhi Village, some houses and vehicles were damaged and four villagers were slightly injured. Before the tornado hit, Jiangsu released the weather forecast 46 minutes in advance.

On the afternoon of July 29, 2020, there was a spectacle of "dragon sucking water" in Qing 'an County, Suihua City, Heilongjiang Province, and the huge cloud column kept spinning.

On the morning of August 5, 2020, Erhai Lake in Dali, Yunnan Province was shocked by the phenomenon of "dragon absorbing water". A huge water column connects the clouds and Erhai Lake, and the scene is shocking.

Tornado conditions include near-surface wind shear, vertical motion and energy instability. Thunderstorm is an ideal environment that can meet the above conditions, and it is also the main cause of tornado. Tornadoes caused by supercells are called supercell tornadoes, and other cases are called non-supercell tornadoes.

Supercell tornadoes account for 80% of the total number of tornadoes, and their intensity and development scale are usually larger than those of non-supercell tornadoes.

Tornado is a meteorological disaster. Modern weather forecast can warn tornadoes through high-frequency observation, but it requires high forecasting experience. In addition, some areas also carry out manual observation and data collection on tornadoes, that is, the "storm discovery" project.
