Strange weather phenomenon

Tornadoes are also different in size. I can tell you responsibly that what you described is a standard tornado. I suggest you search for pictures of tornadoes in Baidu pictures to see if they are similar. In fact, as you described, most tornadoes are very small and thin, and some are even too small to reach the ground. In fact, that kind of huge and thick tornado rarely happens, just because once it happens, it is very easy to cause great damage, so it attracts people's attention and there are many publicity reports, giving many people the wrong impression that a tornado must be huge and thick.
