What is the phenomenon of temperature inversion in the troposphere

It is low air and hot at the top and cold at the bottom.

There is no upper and lower air convection.

It will put the gas in this area in a relatively dull state.

It is easy to fog, and pollution does not spread.

Both the isostratosphere and the inversion layer indicate that the atmosphere is stable, and if they occur near the ground, they will limit the occurrence of strong turbulent movements in the layer, and if they form at a certain height in the troposphere, they will hinder the development of vertical motion below. Therefore, the isothermal layer and the inversion layer are also collectively referred to as the blocking layer.

Ground radiative cooling, air advection cooling, air sinking warming, air turbulent mixing, etc. Inversion layers are likely to occur under the control of ridges of high pressure (e.g. subtropical ridges of high pressure, southward movement of continental anticyclones) or subsidence zones on the periphery of tropical cyclones.

Hazards

In the inversion layer, the warmer and lighter air is located on top of the colder and heavier air, forming an extremely stable air layer, just like a pot lid, shrouded in the air near the surface, seriously hindering the convective movement of the air, due to this reason, the water vapor, smoke and dust and various harmful gases in the air near the surface have no way to go to the sky and no door to enter the ground, only floating in the air layer below the inversion layer.

It is conducive to the formation of clouds and fog, and reduces visibility, brings trouble to transportation, and more seriously, makes the pollutants in the air unable to spread in time, aggravates air pollution, and brings harm to people's lives and property.

The phenomenon of tropospheric inversion refers to an increase in the temperature inside the troposphere. The troposphere is a layer in the Earth's atmosphere, located at an altitude range of about 6 km to 16 km below the Earth's surface. Warmer temperatures in the troposphere mean that the air temperature will increase, which can be detrimental to people's outdoor activities.

Especially in the hot weather of the town area, the rising temperature can make people feel hot and uncomfortable. If the temperature rises too much, it can have an impact on people's health and can even be life-threatening. As a result, tropospheric inversion can be detrimental to outdoor activities.

Under normal circumstances, every 100 meters of increase in the bottom troposphere temperature is a drop in degrees Celsius.

However, under the influence of some factors, the temperature increases with the rise of altitude (strictly speaking, it is not 100m Celsius near the bottom surface) is called inversion.

Note that it is not possible for the entire troposphere to be inverted, usually in a layer of thickness.

Under normal circumstances, the ground is adiabatic and adiabatic due to the warm earth and the warm atmosphere of the earth, and tends to rise, which is the basis for the vertical movement of the atmosphere. However, in the case of inversion, the atmosphere is warm at the top and cold at the bottom, and the lower atmosphere cannot exceed the upper atmosphere even if it receives the heat replenishment density from the ground during the day, and the vertical movement of the atmosphere is completely stopped, and the atmosphere becomes stable.

Popular Science China, Science Encyclopedia, I would like to make the reverse temperature tremble.

There is no temperature inversion in the troposphere, and the higher the altitude, the lower the temperature.

The stratosphere is intemperate.
