At that time, the wind force of the original tornado was only 9, why was the destructive power so strong?

Kaiyuan, Liaoning, China was hit by a tornado of magnitude 9 on July 3, 20 19 17. The scene in the community is simply unsightly. It is very common that cars are blown over and motorcycles are blown onto the roof. But these are just small scenes. What is even more surprising is that the bus of a bus company in Tiexi District was blown down. ...

1.20 19 the wind force of kaiyuan tornado is only 9, why is it so destructive?

The reason for the formation of tornadoes is that the cold air keeps falling and the hot air keeps rising to form a small vortex. The main reason is that the temperature difference between the upper and lower clouds is too large, and cumulus clouds will appear in the air at this time, shaped like cotton candy. These cumulonimbus clouds develop into cumulonimbus clouds in the vortex formed by air, and with the continuous warming, they gradually produce powerful airflow.

According to the meteorological department, Taiyuan, Liaoning Province was affected by strong convective weather, and gradually moved from the initial northwest to the south, which had a huge impact on surrounding houses and lampposts, and even local power outages occurred in some places.

During the tornado, the local temperature even dropped by 10 degrees in a short time, and the precipitation was close to 25mm, which caused a serious blow to the surrounding living environment. Netizens also recorded a variety of tornadoes in Kaiyuan, Liaoning Province, and some of the videos provided were mixed with northeast accent dialects.

Second, what are the characteristics of tornadoes?

1, the duration of tornado is the shortest.

Tornadoes are very different from what we usually call typhoons. Although they are all accompanied by rainfall, the duration of tornadoes is generally short, ranging from a few minutes to less than an hour.

2. Formation of tornado weather

Tornadoes are usually the most common in the afternoon to evening, because the air convection intensity is very strong at this time, and it is very easy to form tornadoes.

3. The incidental range of tornado is very small.

The appearance of tornadoes is generally local, with a diameter of tens to hundreds of meters, and will not cause extensive damage.

The occurrence of tornadoes is very random.

According to the usual weather forecast, it is difficult to predict the appearance of tornadoes and monitor their whereabouts.

5. Tornadoes have extremely high wind speed and extremely destructive power.

According to relevant data, the central wind speed of tornado can reach100 ~ 200 m per second, accompanied by huge suction. Everything around the eye of the wind may be sucked in, trees around it will be pulled up and vehicles will be overturned. These accidents are very common.
