What are the effects of atmospheric circulation?

Atmospheric circulation refers to the vertical and horizontal movement of the earth's atmosphere on a global scale. It has an important impact on the earth's climate, weather and ecological environment. The following are some of the main effects of atmospheric circulation:

1. Climate distribution: Atmospheric circulation determines the climate types of different regions of the earth, such as tropical rain forest, desert and temperate zone. Precipitation distribution: Atmospheric circulation affects the distribution and intensity of precipitation, thus affecting agricultural production and water resources. Storm activity: Atmospheric circulation is the main reason for the formation and development of storms (such as typhoons and hurricanes).

2. Seasonal variation: atmospheric circulation has a great influence on seasonal variation, such as the formation of monsoon climate. Air quality: Atmospheric circulation plays an important role in the diffusion and dissipation of air pollutants. Ecological environment: Atmospheric circulation has an impact on biodiversity and ecosystem stability.

3. Climate change: Atmospheric circulation plays an important role in global climate change, such as extreme climate events caused by El Ni? o phenomenon. Ocean circulation: the interaction between atmospheric circulation and ocean circulation affects the global climate system.

Definition of the Earth's Climate and Related Knowledge

1, the earth's climate refers to the long-term weather and climate conditions in a certain region of the earth, including the average value and variation range of meteorological elements such as temperature, precipitation, wind, cloud cover and wind speed. The formation of the earth's climate is the result of many factors, such as the geographical position of the earth, the rotation and revolution of the earth, solar radiation and so on.

There are many kinds of climate on the earth, among which tropical, temperate and frigid climate are the most common. Tropical climate is usually characterized by high temperature and rain, temperate climate is characterized by four distinct seasons and moderate precipitation, and cold climate is characterized by low temperature, little rain or no rain.

3. The change of the earth's climate is mainly caused by natural factors and human factors. Natural factors include solar radiation, earth orbit parameters (such as earth ellipticity, precession, etc. ), natural disasters (such as volcanic eruptions, earthquakes, etc. ) and so on. Human factors include greenhouse gas emissions (such as carbon dioxide and methane). ), land use changes (such as deforestation, urbanization, etc. ), air pollution and so on.
