I'm from Bogotá, Colombia. In my city the temperature is all the year between 12ºC and 25ºC (bus mostly under 19ºC) and when I drive and it's raining, there is accumulation of fog on the windows, but slowly.
However, I was driving at Miami in summer. I had the windows up and the air conditioner on. In a matter of, the windshield was absolutely foggy. I tried to clean the window with my hand but of course the vapour was outside. My question is, why could that happen so quickly? Does that generally happen? I appreciate your answers.
