What is the vertical stratification of the atmosphere, what is the vertical stratification of the at

The lowest troposphere, the upper stratosphere, and then the upper atmosphere.

The vertical stratification of the atmosphere: from bottom to top: troposphere, stratosphere, mesosphere, warm layer and fugitive layer.

From the top of the mesosphere to the altitude 800 kilometers above the sea surface, it is called the warm (hot) layer, also known as the ionosphere. This layer of air is very dense, and in a layer of 700 kilometers thick, it contains only the total weight of the atmosphere.

According to the detection, at an altitude of 120 kilometers, it is difficult for sound waves to propagate; At an altitude of 270 kilometers, the density of the atmosphere is only 10 billionth of that of the ground, so even if you fire a cannon in your ear, it is difficult to hear anything here. The temperature in the conservatory is very high, according to satellite observations, at an altitude of 300 kilometers, the temperature can reach more than 1,000 meters. So this layer is called the warm layer or the hot layer.

Troposphere

The troposphere is the lowest layer of the Earth's atmosphere. Major atmospheric phenomena such as clouds, fog, rain and snow occur in this layer. The troposphere is the level that has the greatest impact on human production and life, and it is also the key level of meteorology and climatology research.

The troposphere has one main characteristic: the air temperature decreases with altitude: since the troposphere mainly gets its heat from the ground, the air temperature decreases with altitude.

The perennial snow cover in the high mountains, and the clouds in the high altitude are mostly composed of ice crystals, which is a clear manifestation of this characteristic. In the troposphere, the amount of decrease in air temperature with altitude varies depending on factors such as location, altitude and season.

The World Meteorological Organization divides it into five layers, from bottom to top: troposphere, stratosphere, mesosphere, warm layer and fugitive layer.

1. Troposphere.

The troposphere is the lowest layer of the Earth's atmosphere. Major atmospheric phenomena such as clouds, fog, rain and snow occur in this layer. Decreasing air temperature with altitude: Since the troposphere gets its heat mainly from the ground, air temperature decreases with altitude.

2. Stratosphere.

In the stratosphere, as the altitude increases, the temperature initially remains constant or rises slightly. This air temperature distribution in the stratosphere is characterized by the fact that it is not affected by ground temperature, especially because there is a large amount of ozone that can directly absorb solar radiation.

3. The middle layer.

From the top of the stratosphere to about 80 km is the middle layer. This layer is characterized by a rapid drop in air temperature with increasing altitude and a fairly strong vertical movement.

4. Warm layer. Warm layer: It is located above the top of the middle layer. In this layer, the air temperature increases rapidly with altitude. This is due to the fact that the sun's ultraviolet radiation, which is smaller in wavelength, is absorbed by atmospheric material in the layer.

5. A fugitive layer.

This is the highest layer of the atmosphere, also known as the outer layer. The air temperature in this layer changes little with altitude. Due to the high temperature, the high speed of air particles, and the low gravitational attraction due to the distance from the center of the earth, the main feature of this layer is that atmospheric particles often escape into interstellar space, and this layer is the transition zone between the atmosphere and interstellar space.

The basis for the vertical stratification of the atmosphere: temperature, density, atmospheric movement.

Atmosphere is a Chinese word, pinyin dà qì, which means gas that surrounds the earth, and also refers to the gas that surrounds other planets in general. Nowadays, many people also use it to refer to a big heart.

The atmosphere refers to the gas that surrounds the Earth, and also refers to the gas that surrounds other planets in general.

The rough breath he exhaled was so frightened that he didn't dare to come out.

Generous: This kid looks quite atmospheric.

The grandeur and grandeur are magnificent.

Abstract pronoun (referring to being emotionally unhappy) to be angry.

Ye Yusen's poem "Dragon Boat Festival in the Bohai Sea": "The atmospheric flight is windy, and the lonely chant listens to the water dragon." ”

Ye Shengtao's "Ni Huanzhi" 25: "In less than ten minutes, the sound became very grand, as if enveloping the universe and engulfing the atmosphere. ”

Lao She's "Two Horses" first paragraph 2: "He touched the light and turned it on." Then put on a big hat and walked downstairs on tiptoe. ”

The thirty-seventh chapter of "Journey to the West": "When you go to the palace to see your mother, don't be loud, you must whisper." ”

Lao She's "Time-honored Brand": "How many years, Sanhexiang is always so official. Xiao Qian's "Confessions of a Chestnut Melancholy": "I wrote that letter very magnificently. ”

The seventeenth chapter of "Water Margin": "Brother, you have many quick-eyed and quick-moving dukes, and there are three or two hundred, why don't you have some atmosphere with your brother?" If you have a brother, how can you save your brother! ”

The basis for vertical stratification of the atmosphere is as follows:

The whole earth's atmosphere is a tall and unique "building", according to its composition, temperature, density and other physical properties in the vertical direction, the World Meteorological Organization divides this "building" into five layers, from bottom to top: troposphere, stratosphere, mesosphere, warm layer and fugitive layer.

The troposphere is a layer close to the ground where the air near the ground rises when heated, and the cold air located on it sinks, so that convective movement occurs, so this layer is called the troposphere. Its lower bound is the ground, and the upper bound varies according to latitude and season.

It has been observed that at low latitudes its upper limit is 17-18 km; 10-12 km in the mid-latitudes; At high latitudes it is only 8-9 km. The troposphere is thicker in summer than in winter. At the top of the troposphere, up to 50-55 km above sea level, the movement of air currents is quite gentle, and mainly horizontal, hence the stratosphere.

Atmosphere

The atmosphere is also called the atmosphere, and the earth is surrounded by this thick atmosphere. The composition of the atmosphere is mainly nitrogen, which accounts for; Oxygen occupies; argon occupies; There are also small amounts of carbon dioxide, noble gases (helium, neon, argon, krypton, xenon, radon) and water vapor.

The density of air in the atmosphere decreases with altitude, and the higher the air, the thinner it becomes. The thickness of the atmosphere is about 1,000 kilometers or more, but there are no clear boundaries. The entire atmosphere exhibits different characteristics with different altitudes, and is divided into troposphere, stratosphere, mesosphere, warm layer and fugitive layer, and above it is interstellar space.
