An inversion in meteorology is when atmospheric pressure causes an abnormal condition. An example would be that the pressure causes warmer air to sink closer to earth's surface and cooler air to rise higher. When this inversion happens, one of the effects is that pollution and smog stay trapped within our atmosphere.

Meteorology.

Meteorology is not something that can be caused. Meteorology is the study of weather.

The study of meteorology is made up of three branches. These branches are microscale meteorology, mesoscale meteorology, and synoptic scale meteorology.

Why would anybody want to study meteorology?

Meteorology is all to do with the weather.
