Why does the car window fog up on the outside when the air conditioner is on in summer?

[LucilleDella]

In summer, car windows fog up due to the large temperature difference caused by setting the air conditioner too low. Here is relevant information: 1. High-temperature air: The cold air blown out significantly lowers the temperature of the window area. When this cold glass comes into contact with the high-temperature outside air, especially when humidity is high, it easily forms a layer of condensation on the outside. 2. Summer fogging: Unlike winter fogging, summer fogging mostly occurs on the outside of the windows and tends to appear in clustered patches rather than covering the entire window surface. This is the key difference between summer and winter window fogging.
