【Meteorological Tips: Warm Day and Cold Night and Radiative Cooling】The recent cold air, under the sun during the day, may not feel too powerful, but after the sun goes down, the temperature drops significantly, and the cold at night and before sunrise, friends who go out early and return late must experience it profoundly. This is because the sky is cloudless at night on a sunny day, and the ground energy radiates outwards without obstruction, so that the temperature drops significantly until the lowest value of the day is reached in the early morning. Therefore, although the sun is good during the day, don't ignore the presence of cold air, and the temperature drops at night.
