A woman cooked a tornado in her pot. How did it come into being?

"In fact, Ms. Shi perfectly reproduces the meteorological conditions of the dusty wind: the underlying surface is hot and unevenly heated (oil pan heating), the air is dry (the kitchen is on fire on a sunny day), and the high-altitude divergent suction (range hood)."

On this matter, the reporter interviewed a physics teacher in a university in Dalian. He told reporters that this phenomenon is basically consistent with the cause of sandstorm, not a tornado as netizens said. Sandstorms and tornadoes are similar in meaning, but they are actually different.

When the wok is heated, the hot air in the wok rises. The weather in Dalian turned cold, and the outdoor cold air continued to enter. After the hot and cold air meet, the water vapor condenses and drops, forming convection in the pot. Under the combined action of the vertical suction of the range hood and the momentum of the cold air blown into the room, the gas begins to rotate, forming a "dust storm". He said that it is also a coincidence that the situation encountered by Ms. Shi must meet various conditions at the same time. For security reasons, it is not recommended for netizens to imitate.
