What is the cause of temperature inversion?

This is why inversion layers are called stable air masses. Temperature inversions are a result of other weather conditions in an area. They occur most often when a warm, less dense air mass moves over a dense, cold air mass. This cold air then pushes under the warmer air rising from the valley, creating the inversion.
A.

What is the definition of temperature inversion?

Temperature inversion, a reversal of the normal behaviour of temperature in the troposphere (the region of the atmosphere nearest the Earth's surface), in which a layer of cool air at the surface is overlain by a layer of warmer air. (Under normal conditions air temperature usually decreases with height.)
  • What is inversion movement?

    Inversion and eversion refer to movements that tilt the sole of the foot away from (eversion) or towards (inversion) the midline of the body. Eversion is the movement of the sole of the foot away from the median plane. For example, inversion describes the motion when an ankle is twisted.
  • What layer of the atmosphere do you find satellites?

    Exosphere. This is the outermost layer of the atmosphere. It extends from the top of the thermosphere to 6,200 miles (10,000 km ) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth.
  • Why is there a temperature inversion in the stratosphere?

    This rise in temperature is caused by the absorption of ultraviolet (UV) radiation from the Sun by the ozone layer. Such a temperature profile creates very stable atmospheric conditions, and the stratosphere lacks the air turbulence that is so prevalent in the troposphere.
B.

What is the relation between a temperature inversion and atmospheric pollution?

It almost always refers to a "temperature inversion", i.e. an increase in temperature with height, or to the layer ("inversion layer") within which such an increase occurs. An inversion can lead to pollution such as smog being trapped close to the ground, with possible adverse effects on health.
  • What are Ozone Action Days and why are they declared?

    An Ozone Action Day is declared when weather conditions are likely to combine with pollution emissions to form high levels of ozone near the ground that may cause harmful health effects. People and businesses should take action to reduce emissions of ozone-causing pollutants.
  • What happens to the temperature as you increase in altitude in the stratosphere?

    In the layer above the troposphere, the stratosphere, temperature rises with increasing altitude. In the stratosphere, the air is heated from above by ultraviolet "light" which is absorbed by ozone molecules in the air. The tropopause is the boundary between the troposphere (below) and the stratosphere (above).
