Page "Inversion (meteorology)" Paragraph 2

An inversion can lead to pollution such 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.
