What is a thermal inversion?

A thermal inversion is a weather event in which a layer of warm air sits above a layer of cooler air. 

This can lead to various weather phenomena, such as a situation when smog is trapped near the ground.

How is it formed?

Usually, temperature inversions occur when there is a high-pressure system in the atmosphere. The high pressure system acts like a lid, trapping the warm air near the ground.

How does temperature inversion impact the environment?

Temperature inversion can have a number of impacts on the environment. It can:

• Have a negative influence on air quality – the inversion traps pollutants in the lower atmosphere.
• Increase smog and pollution levels that result in respiratory and circulatory conditions.
• Impact local weather patterns – the temperature inversion can trap cold air near the ground, leading to cooler temperatures and increased cloud cover.

Why can temperature inversion be harmful?

Although temperature inversion isn’t dangerous per se, it can cause air pollution to become trapped in a layer of warm air. This means that air pollutants can also be near the ground. Thus, making people and animals more exposed to harmful substances such as smog, carbon monoxide, nitrogen dioxide, and sulfur dioxide.

As a result of long-term exposure to the abovementioned pollutants, people can suffer from:

• circulatory and respiratory problems,
• asthma,
• nausea,
• problems with concentration,
• strokes,
• heart attacks,
• cancer,
• or even premature death.

Therefore, it’s worth monitoring air quality on an ongoing basis to stay informed and make accurate decisions regarding your outdoor activity. For this purpose, you can use special apps, maps, and sensors.

Thanks to them, you can limit the amount of time you spend outside when the air quality isn’t satisfactory.

The takeaway

A thermal inversion is a weather event that can have a number of impacts on air quality and local weather patterns. Although it isn’t dangerous itself, it can trap air pollution in a layer of warm air, making people and animals more exposed to harmful substances.
