WHAT IS THE THERMAL INVERSION?

The thermal inversion is a condition in where the air increases as we ascend and decreases where descend. This occurs in winter.

On a clear night the ground coolsrapidly and loses heat by radiation, in turn cools the air that comes in contact with him making it cooler than the one in the upper layers close to him, which causes it to generate a temperaturepositive with respect to altitude. This causes the hot air layer trapped between two layers of cold air can not move, since the presence of the layer of cold air near the ground gives great stability.This cold air is heavier, can not rise and does not mix.









Generally, the inversion is completed (breaks) when heating the ground which restores normal circulation in the troposphere.The weather phenomenon normally occurs on cold mornings the valleys of low air circulation in all terrestrial ecosystems or the entry of cold fronts into the region.Recommendations.

• Use public transport instead of private vehicles and will reduce air pollution significantly.

• Keep your vehicle in good condition: tires, filters, exhaust .

• Respectthe green areas of the city.

• Refer Contingency Response Program.




In meteorology, an inversion is a deviation from the normal change of an atmospheric property with altitude. Italmost always refers to a "temperature inversion", an increase in temperature with height, or to the layer ("inversion layer") within which such an increase occurs.

An inversion can lead to pollutionsuch as smog being trapped close to the ground, with possible adverse effects on health. An inversion can also suppress convection by acting as a "cap". If this cap is broken for any of several reasons,convection of any moisture present can then erupt into violent thunderstorms. Temperature inversion can notoriously result in freezing rain in cold climates.
