I want to ask a high school geography question.

I am a geography teacher. I hope my answer can help you.

Geographical Theorem: On the same horizontal plane, air pressure is inversely proportional to air temperature?

? Altitude is inversely proportional to air pressure.

Altitude is inversely proportional to temperature.

As shown in the figure, (1)? A is on line A and B is below line A, which means that the temperature of B is higher than that of A and the air pressure is lower than that of A,

A cycle is formed everywhere: A → B → D → C.

(2)? A is on line A and B is below line A, which means that the air pressure of B is higher than that of A, so the wind blows from B to A,

There is a cycle everywhere: B → A → C → D → B

PS: Pay attention to my premise. At the same level, if the temperature is high and the air pressure is low, and the land temperature is high and the air pressure is low in summer in China, the wind will blow from the ocean to the land. Speaking of altitude, this theorem doesn't hold.

As shown in the figure, the altitude of Lhasa is higher than that of Chengdu, but Lhasa only bears the pressure of L 1, while Chengdu bears the pressure of L2. So Lhasa has low air pressure, thin air and fine weather. It is the Sunshine City of China, with low oxygen content and low boiling point.

Chengdu is the place with the least solar radiation in China because of its high air pressure, changeable weather and cloudy days.
