Why is it sometimes foggy in the morning, but you say it will be fine?

The villagers shouldn't have done anything wrong at all, saying that the sun dispersed as soon as it came out of the fog. Today is a poisonous day. Sure enough, the fog disappeared long before the sun climbed to the height of the telephone pole. The old farmer said that if you cover the fog in the morning, you can wash your clothes and pants. It's foggy in the morning, drying gourds. There is an old saying in the countryside, ten fogs and nine sunny days. "There are many kinds of fog, and there are different forms in spring, summer, autumn and winter. We will reduce complexity and simplify it. Remember these five special cases, and we will be able to see the fog and know the sky like old farmers. Fog appears in different seasons, showing different climatic characteristics. Rural folk proverbs say that the sun is foggy in spring, foggy and rainy in summer, foggy and cool in autumn and foggy and snowy in winter. In other words, there are many foggy days and sunny days in spring. It is foggy in summer, and it rains frequently. Autumn fog, a layer of fog with a layer of coolness. It's foggy in winter, so it should be cold and snowy.

A rural folk proverb in Jiaodong says that spring fog exposes dead ghosts and summer fog floods, which also illustrates the difference between spring fog and summer fog. There are many kinds of fog in this country. Judging from the color of fog, there is a folk saying that white fog is good. Fog, black rain. Don't worry about that white fog, don't be afraid. The fog cleared at sunrise when you went out. If the fog covers you, you should be prepared in advance to avoid being caught in the heavy rain on the way. There is a saying in agriculture that rainy mountains wear hats and rainy rivers are covered. There is a mountain called Wuyun Mountain in the county where Axi is located. The local villagers regard Wuyun Mountain as a barometer. As long as you see the clouds on the top of the mountain, like wearing a hat made of fog, you will know that it is going to rain. There is also a folk proverb: when the fog rises to the top of the mountain, there will be a downpour; Fog scattered the earth, no wind and no rain. It's easier to understand. Generally speaking, it is foggy during the day and sunny and rainy at night. As long as the fog in the morning is normal white, it can basically be judged as sunny. It is foggy and rainy at night.

The farmer's proverb says that it will rain that day if the fog is not collected. It's sunny and foggy for a long time, and cloudy and foggy for a long time. Experienced farmers know it will rain on cloudy days when they see fog after continuous sunny days. On the contrary, if it is cloudy all the time and suddenly one day it is shrouded in fog, the old farmer will know that he will finally hit the sky and shine. There will be fog and heavy rain in three days. It was sunny and cloudy for a long time. If it is foggy for three days in a row, it will definitely rain heavily. This is the law of nature. Look at the stars in the long rain. The rain in the Ming Dynasty is even crazier. If it suddenly clears up for a while on a cloudy day with continuous rain, don't be too happy if you really see the long-lost stars. Because this is not a sign of sunny day, but it tells you that it will rain harder and harder tomorrow. Take advantage of the free time when the rain stops, quickly pick out all the ditches, fan up the reinforced and covered places, and prepare to continue to meet the challenge of heavy rain.

This kind of fog is generally generated near high pressure, and there are often no rain clouds near high pressure. In this way, the sun can shine directly on the fog. The warm sunshine evaporates the water droplets in the fog, dispels the fog, and the sky will clear up. This day is usually sunny. When the sun shines on the ground, a lot of heat is accumulated on the ground. Because of the evaporation of water, the air with higher temperature can hold more water vapor, so there is more water vapor in the air. After the sun went down, heat began to radiate into the air, and the air temperature near the ground decreased. The better the weather, the less clouds in the sky, and the heat on the ground is not hindered. The faster the radiation, the lower the air humidity. At midnight and early morning, the temperature of the ground air drops very low. At that time, even indoors, we could easily feel the coolness of the last night. When the temperature near the ground drops, the water vapor in the air exceeds the saturation state, and the excess water vapor condenses into tiny water droplets, which are distributed at low altitude. This is called radiation fog in meteorology, which generally appears near the high pressure center, and it is often sunny near the high pressure center. So when this fog appears, although it is very thick in the morning, as long as the sun comes out to evaporate the fog, it is mostly sunny.
