Why do you often see or hear planes in the same area (I am in Changsha) in summer and hardly see or hear them in winter? Is it the temperature?

Clouds are thin in summer and thick in winter, and suspended matter (clouds and dust clouds, etc.). ) will scatter sound waves and prevent them from reaching the ground.

Wan Li is often cloudless in the summer of Wanli, and people can see it with naked eyes. In winter, the clouds are thick, so it is not easy to see planes.
