Winter fog usually dissipates at what time in the morning, which depends on many factors, including temperature, humidity, wind speed and terrain. Generally speaking, when the temperature rises, the humidity drops, the wind speed increases or the sun rises, the fog will gradually dissipate.
In winter, due to the low temperature at night, the heat emitted from the ground will be absorbed by the water vapor in the atmosphere, forming fog. Usually, after the sun rises in the morning, the temperature begins to rise, the water vapor begins to evaporate gradually, and the fog will gradually dissipate. However, if the weather is overcast, the temperature is too low, the humidity is too high or the wind speed is too small, the fog may last until the morning or noon.
In addition, the terrain will also affect the fog dissipation time. In mountainous areas or river valleys, due to the undulating terrain, the changes of temperature and humidity will be more complex, and the time of fog dissipation may be prolonged.
Therefore, the time for fog to dissipate in winter is not fixed, and various factors need to be considered. Generally speaking, if the weather is sunny, the temperature is appropriate, the humidity is low, and the wind speed is moderate, the fog may dissipate around 8:00 in the morning. However, if the weather is bad or the terrain is complex, the fog may last until the morning or noon.
