The fog in the morning shows the weather.

Fog in the morning means sunny weather.

The morning fog is caused by high humidity and cold in the air. The sun will gradually dissipate after rising, which indicates that the weather will be clear and cloudless today. Generally, there is more fog in autumn and winter morning, and it is usually very cold after fog. The temperature is higher during the day, so the air can hold more water vapor. It's foggy in the morning, and the temperature will rise after the fog.

Fog occurs at night, because the temperature drops and the air is quite humid. When it cools to a certain extent, some water vapor in the air will condense out and become many small water droplets suspended in the air layer near the ground, so the fog lasts for a long time, and then the temperature will drop.

Fog introduction

Fog is a common weather phenomenon, which refers to water vapor condensate composed of water droplets or ice crystals suspended in the atmosphere near the earth's surface. When the temperature reaches the dew point temperature (or near the dew point temperature), the water vapor in the air condenses to form fog. The difference between fog and clouds is that clouds are produced in the upper atmosphere, while fog is close to the surface.

There are several different types of fog according to the cause of condensation. When the temperature is above freezing point, water vapor condenses into water droplets. When the temperature is below freezing point, water vapor condenses directly into solid ice crystals, such as ice fog. Because dew point is only affected by air temperature and humidity, there are two main reasons for the formation of fog: first, the water vapor in the air increases greatly, which makes the dew point rise to air temperature, thus forming fog.
