The influence of cold wave on human beings

The impact of the cold wave on human beings is as follows:

1, Life impact: Cold wave weather will increase the demand for heating, and increase the pressure on energy supply such as electricity and gas. At the same time, people's travel will also be affected due to icy roads and traffic jams. In addition, the cold wave may also damage crops and affect agricultural production. Environmental impact: Cold wave may lead to some environmental problems, such as frozen soil melting and avalanches.

2. Economic impact: The cold wave will have a serious impact on agriculture, animal husbandry, fisheries and other industries, resulting in a decline in output and an increase in prices. At the same time, due to the increase in heating demand, the prices of energy such as electricity and gas may also rise. In addition, the cold wave may also lead to a decrease in business activities and affect economic development.

3. Social impact: Cold wave weather may cause schools and factories to suspend classes and affect the normal social order. At the same time, due to the increase of heating demand, the pressure of energy supply such as electricity and gas increases, which may cause some social problems, such as energy shortage and power failure. Psychological influence: Long-term cold weather may affect people's psychological state, leading to psychological problems such as depression, anxiety and depression.

Formation of cold wave

1. Climate change: Global warming causes cold air in polar and alpine regions to go south, and warm and humid air in tropical regions to go north, which provides necessary meteorological conditions for the formation of cold waves. High-altitude jet: Before the cold wave occurs, the high-altitude jet will generally strengthen, which provides dynamic conditions for the occurrence of the cold wave. When the jet stream intensifies, the cold air will accelerate southward, thus forming a cold wave.

2. Polar high: Polar high is the main cold air source of cold wave. Under the action of polar high pressure, cold air will go south and gradually strengthen, eventually forming a cold wave. Convection of cold and warm air mass: When cold air in the north meets warm and humid air in the south, it will produce large-scale convergence of cold and warm air, which provides important meteorological conditions for the formation of cold wave.

3. Topographic factors: China is located in the east of Asia, facing the Pacific Ocean, and is greatly influenced by the East Asian monsoon. The northern region is often affected by cold air from Siberia and the Mongolian Plateau, while the southern region is often affected by warm and humid air from the ocean. This special terrain makes China vulnerable to cold waves. Human activities: Human activities will also have a certain impact on the formation of the cold wave.
