Weather phenomena mainly occur in the atmosphere.

Weather phenomenon refers to various natural phenomena in the atmosphere, including wind, clouds, precipitation, temperature, air pressure and so on. These phenomena mainly occur in the atmosphere, that is, the atmosphere about 10- 15 kilometers away from the earth's surface.

The atmosphere is a layer of gas around the earth, which surrounds the earth and is an important interface between the earth's surface and the external environment. In the atmosphere, the formation and change of weather phenomena are the result of the comprehensive action of various meteorological factors.

Wind is air movement caused by air pressure difference, and high-pressure air will flow to low pressure to form wind. At the same time, the rotation of the earth will also make the air movement deviate, forming various wind directions and speeds.

Clouds are formed by condensation of water vapor in the atmosphere. According to different heights, it can be divided into low clouds, medium clouds and high clouds. The formation of clouds is closely related to meteorological factors such as temperature, humidity and air pressure.

Precipitation refers to the water falling from the clouds to the ground, including rain, snow, fog, dew and frost. The formation of precipitation is related to the thickness, temperature, humidity, wind direction and wind speed of clouds.

Temperature refers to the average thermal motion energy of molecules in the air, which is the degree of cold and hot air in common parlance. The temperature is affected by latitude, altitude, terrain, season and other factors.

Air pressure refers to the weight of air column per unit area, which is the pressure of air in popular parlance. The level of air pressure is closely related to the weather change. The high-pressure weather is sunny, and the low-pressure weather is gloomy and rainy.

The influence of weather change on human beings;

1, weather changes have an important impact on agricultural production and food supply. Different climatic conditions have different effects on the growth and maturity of crops. Too cold or too hot may cause damage to crops. Extreme weather events such as floods, droughts and storms will cause serious damage to crops and affect food supply.

2. Weather changes will also have an impact on human health. Extreme weather conditions may cause some diseases, such as cardiovascular diseases and respiratory diseases. In addition, the change of weather may also lead to the spread of pathogens such as bacteria and viruses, thus triggering various epidemics.

In addition, weather changes will also have an impact on human living environment. Extreme weather events may lead to house damage, road interruption, power supply interruption, etc. , affecting people's normal life. At the same time, the change of weather may also cause natural disasters, such as mountain torrents and mudslides, which pose a threat to the safety of human life and property.

3. Weather changes will also have an impact on human economic activities. Changes in the weather may affect the production and operation of enterprises. For example, heavy rain may hinder logistics, and high temperature weather may lead to insufficient power supply. At the same time, weather changes may also affect the operation and development of tourism, for example, snowstorms may close tourist attractions, and high temperature weather may reduce tourists.
