Why is the weather forecast sometimes three straight lines, and sometimes it is?
Fog is a natural phenomenon, which is common in autumn and winter. The formation principle of fog is to condense water vapor in the air into fine water droplets suspended in the air, which reduces the horizontal visibility of the ground. To form fog, it is necessary to reduce temperature, humidify and increase water vapor content. There are many kinds of fog, radiation fog and advection fog. The straight line is generally because there is an obvious front (the cold and warm peaks are obvious), while the curve is that the cold and warm peaks are not obvious.

Wear a mask when going out in foggy weather. There are harmful substances and particles in the fog, which is not good for your health.
When driving or go on road trip, be sure to turn on the light. One is to penetrate the fog to improve the visual range, but other vehicles can see it to avoid vehicle collision.
When driving out or driving, you must slow down, keep the distance between cars, and honk your horn in time to prevent traffic accidents.
Because it is inconvenient to travel in foggy days, people who go to work must go to work earlier than usual, otherwise it is easy to be late.
