What impact does fog have on our lives in the morning?
The impact of heavy fog
1. The losses caused by fog are very alarming. Heavy foggy weather caused low visibility on the ground, making it impossible for aircraft to take off and land normally. Beijing Capital International Airport experiences "foggy harbor" for several days almost every year. A large number of flights are delayed or canceled, causing great inconvenience and losses to passengers and civil aviation.
2. Mist adheres to the surface of insulating equipment such as porcelain bottles and hanging bottles on transmission lines, causing the insulation performance of power transmission and transformation equipment to decrease, leading to short circuits and tripping of high-voltage lines, which is the so-called "pollution flashover disaster." Heavy fog destroyed the porcelain insulation of high-voltage transmission lines, causing widespread power outages.
3. In terms of health, due to excessive humidity in foggy days, people have difficulty breathing, feel depressed and uneasy, and the incidence rate is significantly increased.

Causes of fog
Heavy fog often appears after rainfall, when the water vapor near the ground is saturated, the air humidity is high, and the subsequent cold high pressure system It brought sunny weather, coupled with relatively light winds, the temperature dropped significantly. In late autumn and early winter, the temperature difference between day and night increases, making it easy for water vapor to condense.
Sunny weather provides enough dust particles to serve as water vapor condensation nuclei. At the same time, due to the low wind, pollutants cannot be diffused, causing an increase in suspended particles in the air. These conditions have contributed to The formation of heavy fog.
The warm and humid airflow east of the Tibetan Plateau continues to be transported to northern and eastern my country, making the air in the lower atmosphere more humid and containing more water vapor. In early winter, the temperature is low, which makes the ground humid and meets the conditions for heavy fog condensation. The cold air activity has been weak in recent days, and the wind in the above-mentioned areas is very small, resulting in stable atmospheric stratification, which is conducive to the formation of dense fog.
