Variation law of natural meteorology

I am a geography teacher major. Let me sum it up for you. As said upstairs, there is some inconsistency between encyclopedia and book. The following is all the high school knowledge I have summarized.

I. Troposphere

1. Three quarters of the atmospheric mass and almost all the water vapor and impurities are concentrated together, and the thickness varies with latitude.

The thickness of low latitude is about17 ~18 km; The mid-latitude thickness is about10 ~12 km; The thickness of high latitude is about 8~9 kilometers.

2. Features: the temperature decreases with the increase of height, the air convection movement is obvious, and the weather phenomenon is complex and changeable.

Second, the stratosphere

1 There is a large amount of ozone layer that absorbs ultraviolet rays, and its height ranges from tropopause to 50 ~ 55km.

2. Features: The temperature rises with the altitude, the atmosphere is dominated by advection, and the weather is fine, which is conducive to high-altitude flight.

Third, the upper atmosphere

1. The altitude is 2000~3000 km from the stratosphere top.

2. Features: The air density is very low, the air pressure is very low, and there is an ionosphere at high altitude, which is conducive to radio communication.
