Did you know this interesting fact? In winter, clear nights tend to be much colder than overcast nights. This phenomenon primarily arises from two reasons:
– First, on clear nights with no clouds, the heat absorbed by the ground during the day rapidly dissipates, causing the air temperature to drop. In contrast, overcast nights with clouds act like a giant blanket, preventing the heat from escaping easily, thus preserving the ground temperature to some extent.
– Second, clear days often coincide with the arrival of dry, cold air, whereas overcast days are typically associated with warm, moist air blowing in from the ocean. Therefore, during winter, there is usually a noticeable temperature difference between cloudy days and clear days.
