Knowledge points of atmospheric heating process and atmospheric movement in geography senior one.

Atmospheric heating process and atmospheric motion are important knowledge points in geography. The process of atmospheric heating mainly involves solar radiation, ground radiation and atmospheric radiation, and atmospheric movement involves the formation of wind and atmospheric circulation.

I. Atmospheric heating process

1, solar radiation

The sun is the main energy source of the earth and transmits energy to the atmosphere through solar radiation. Solar radiation is an important driving force of the earth's climate system, which keeps the earth's surface temperature relatively stable.

2. Ground radiation

After the ground absorbs solar radiation, it will transfer energy to the atmosphere in the form of ground radiation. Ground radiation is an important link in the process of atmospheric heating, which keeps the temperature in the atmosphere relatively stable.

3. Atmospheric radiation

After the atmosphere absorbs ground radiation, it will transfer energy to the earth's surface in the form of atmospheric radiation. Atmospheric radiation is an important way of heat exchange between the atmosphere and the surface, which keeps the surface temperature relatively stable.

Second, the atmospheric movement.

1, the formation of wind

The uneven distribution of solar radiation leads to the temperature difference in different parts of the earth. This temperature difference produces horizontal pressure gradient force, which makes air flow from high pressure area to low pressure area, thus forming wind. Wind is a manifestation of atmospheric movement, which has an important impact on the earth's climate, environment and human activities.

2. Atmospheric circulation

Under the influence of the earth's rotation and solar radiation, the air in the atmosphere will form a large-scale circulation. These circulations have an important influence on global climate and weather, and ocean currents and monsoons are both manifestations of atmospheric circulation. Atmospheric circulation makes the climate on the earth present complex and diverse characteristics.

Application fields of atmospheric heating process and atmospheric motion

1, weather forecast and climate forecast

Meteorologists can predict future weather changes, such as temperature, humidity, wind direction and wind speed, by studying atmospheric heating process and atmospheric movement, and provide reference for people's life and agricultural production. At the same time, these studies are also helpful to predict climate change and provide scientific basis for coping with global climate change.

2. Air quality monitoring and environmental protection

Atmospheric movement affects air quality. By monitoring the atmospheric movement and air quality, we can understand the diffusion and distribution of air pollutants and provide a basis for environmental protection. This is of great significance for protecting human health and ecological environment.

3. Agrometeorological services

By studying the atmospheric heating process and atmospheric movement, we can understand the agricultural meteorological conditions and provide meteorological services for agricultural production, such as meteorological disaster early warning and crop growth environment monitoring. This will help to improve the efficiency and output of agricultural production and protect the ecological environment.

4, energy utilization and energy saving and emission reduction

By studying the atmospheric heating process and atmospheric movement, we can understand the key factors of energy utilization such as solar radiation and surface temperature, and provide scientific basis for the development and utilization of renewable energy such as solar energy and wind energy. At the same time, these studies also contribute to energy conservation and emission reduction, reduce greenhouse gas emissions and slow down global climate change.

5. Military meteorological support

The study of atmospheric heating process and atmospheric motion is also of great significance for military meteorological support. Understanding the influence of meteorological conditions on military operations can make more reasonable military plans and action plans and improve the efficiency and safety of military operations.
