2. There should be condensation nuclei,
3. Clouds turn into raindrops,
4. Overcome resistance and jacking.
the first two are the conditions of water vapor condensation, and all four are the conditions of rainfall formation.
the main way to make the air supersaturated is: the air rises and cools.
sometimes, when the temperature drops sharply near the ground, the air can be supersaturated without rising and cooling, and then fog is formed.
Now, our country is in winter, the temperature is low, and there is less water vapor in the air, so it is not easy to achieve supersaturation. At the same time, due to the low temperature, the proportion of air is large, so it is not easy to rise, and then it is not easy to cause rain. But at night, a lot of heat is lost near the ground, and the temperature drops sharply near the ground, and the air can reach supersaturation without rising and cooling, so fog is formed.
therefore, foggy weather is more likely to occur in winter, but it is less likely to occur in rain and snow.
