Can I run in heavy fog?

It is best not to run. Heavy fog or thick fog has occurred from time to time recently, causing serious traffic accidents on some highways and causing casualties. Fog is a common atmospheric condensation phenomenon, especially in autumn and winter. There are many seasons. When heavy fog occurs, a large number of tiny water droplets or ice crystals are suspended in the air near the ground, making the air turbid and reducing visibility. People can only see people or objects nearby. Generally, the horizontal visibility of the air is less than 1,000 meters. It is called fog, and the visibility of the recent heavy fogs that have caused major traffic accidents is less than 100 meters. There are two basic conditions for the formation of fog: first, there is sufficient water vapor in the air near the ground, and it can reach a saturated state when it is cold; Second, the wind force is very small at night, the atmosphere structure is relatively stable, and there are sufficient condensation nuclei and suspended matter. When fog forms, it is often accompanied by the existence of a corresponding temperature inversion layer. That is to say, in the section near the ground, the closer to the ground The lower the temperature, the higher the temperature goes up. This is just the opposite of normal weather conditions. Fog gradually forms at night and reaches its highest concentration in the morning. After the sun comes out, the ground temperature rises, and the dense fog gradually thins until it dissipates. Therefore, there is a saying that "ten fogs and nine clears". If it does not dissipate for a long time, it will rain. This is mostly related to the passing of fronts in autumn and winter. Fog does not fall from the sky. It and clouds are caused by the drop in temperature in the atmosphere. It is caused by the condensation of water vapor. Fog can actually be said to be clouds close to the ground. The so-called "soaring into the clouds and driving the fog" means that clouds and fog are similar things, but they are located in different spaces. Fog is a kind of disastrous weather and is listed on the international It is one of the ten most severe weather conditions.
