Why do the layers of the atmosphere have different temperatures?

The first is that the height of each layer is different!

The temperature of the part close to the ground** is the thermal radiation of the ground, and the troposphere brings the air close to the ground to higher space, during which of course there is a heat loss; Others think of the difference in temperature due to the difference in the elements contained in the ozone zone, ionosphere, etc.

The above are all personal opinions, using the geography knowledge learned in the first year of high school, if there is anything inappropriate, I hope to forgive me!

Hehe!!!

The air near the Earth's surface is heated by the surface, so the higher the temperature, the lower the temperature.

The atmosphere is divided into the troposphere, the stratosphere and the upper atmosphere, and the radiation is divided into long-wave radiation and short-wave radiation, and the troposphere can only be heated by the long-wave radiation absorbed by the ground, so the higher the colder, and the stratosphere absorbs short-wave radiation. Think of the rest!

The height is different. The atmosphere is divided into the troposphere, stratosphere, and upper atmosphere. The ground is the direct heat source of the troposphere, while the direct heat source of the upper atmosphere is the sun, and the different densities of the layers should also have an effect.

Weather phenomena generally occur in the troposphere of the atmosphere. The atmosphere is divided into five layers, and the troposphere is home to three-quarters of the mass of the atmosphere and most of the water vapor, and there is a strong vertical movement, so the main weather phenomena and processes such as cold waves, typhoons, thunderstorms, lightning, etc., occur in this layer. The vertical rate of decline of temperature near the tropopause abruptly changed, and the temperature remained basically unchanged or increased slightly with altitude.

Introduction to the troposphere.

The troposphere refers to the layer of atmosphere closest to the Earth's surface, and it is also the lowest layer of the atmosphere and has the highest density. The troposphere is called troposphere due to the influence of different terrains such as surface forests, lakes, grasslands, beaches, mountains, etc., and the change of temperature caused by sunlight, which causes a large amount of convection in the vertical and horizontal directions, that is, the air.

The lower limit of the troposphere is connected to the ground, and the height of the upper limit varies with geographical latitude and seasonality, and its altitude varies from latitude to latitude, with an average altitude of 17 18 km in low latitudes, 10 12 km in mid-latitudes and 8 9 km in the polar regions.

For example, in the Beijing area of China, the height of the troposphere is about 11 km, the height of the troposphere in the Guangzhou area increases to about 16 km, and in the northeast region it decreases to 10 km. And the summer is higher than the winter.

Even on the same day in the same region, the height of the troposphere can vary with the change of morning, middle and evening.
