Radiation fog typically forms on clear, calm nights. As the ground cools down after sunset, it radiates heat and cools down the air in contact with it to its dew point, leading to the formation of fog. Windy conditions (choices A and C) can prevent the formation of radiation fog by mixing the air near the ground and preventing it from cooling down. Clear, calm days (choice D) do not typically lead to fog formation as the ground heats up during the day, preventing cooling and moisture from condensing.
