Is atmospheric reverse radiation strong or weak in dense fog?

Dense fog absorbs ground radiation and enhances atmospheric reverse radiation. Heavy fog refers to a weather phenomenon in which horizontal visibility is less than 500 meters due to countless small water droplets or small ice crystals suspended in the air near the ground. Heavy fog mainly occurs on sunny days when the temperature difference between day and night is large.

During the spring, autumn and rainy seasons, under the influence of the high-pressure return before the front arrives, large-scale and long-lasting dense fog often appears. Dense fog will block visibility. If the visibility is less than 200 meters, it will affect land or sea transportation. The Meteorological Bureau will issue a "Dense Fog Special Warning" in areas or sea areas where dense fog occurs.

Coping with smog weather

(1) Go out as little as possible: Due to the existence of large and small particles in haze weather, it seriously harms your health. After the particles enter the body, they will stick to the respiratory tract. Cause bronchitis and pharyngitis. In particular, the elderly and those with respiratory diseases who have relatively weak resistance should reduce travel or wear masks to protect their bodies when exercising outdoors.

(2) Morning exercise should be limited: Many people are more accustomed to morning exercise. In fact, the time is not very correct for the human body. Due to the air exchange environment in the morning, the air quality is very poor, especially haze. Weather and respiratory tract are easily irritated, which can easily induce respiratory and cardiovascular and cerebrovascular diseases during exercise.
