Stratospheric characteristics

1. The temperature is vertically distributed over 30 kilometers, but it increases rapidly with the increase of height except that the lower level does not change much with height. This is because ozone in the stratosphere absorbs a lot of ultraviolet rays from the sun, which makes the temperature rise.

2. The atmosphere is dominated by horizontal movement. The upper stratosphere is hot, the lower stratosphere is cold, the atmosphere is stable, and convection is not easy to form.

3, the content of water vapor and impurities is very small, and the phenomenon of cloud and rain is almost extinct. The atmosphere is stable and the weather is clear, which is conducive to high-altitude flight.

Stratosphere, also known as stratosphere, is a layer of the earth's atmosphere, which is hot at the top and cold at the bottom. This layer is divided into different temperature layers, the high temperature layer is above and the low temperature layer is below. It is just the opposite of the troposphere below it near the surface. The troposphere is cold at the top and hot at the bottom. In mid-latitudes, the stratosphere is located at a height of 0/0 km to 50 km from the surface/kloc-0, while in polar regions, this layer starts about 8 km from the surface. The reason why the stratosphere is contrary to the troposphere, and the temperature rises with the increase of height is because its top absorbs the ultraviolet rays of the sun and is heated. So on this floor, the temperature will rise because of the height.
