Living in Oklahoma, we were curious about how the weather affects air quality. This state experiences some extreme weather conditions, such as tornadoes, rain, and wind during springtime, while during summer, extreme heat, humidity, and drought. In contrast, the winters bring with them bone-chilling cold, wind, ice, and snow.

How Air Quality is Measured

Air quality can be measured using the Air Quality Index (AQI), which is graded on a scale of 0 to 500. Any reading above 150 is considered unhealthy, and a reading above 300 is considered hazardous. The AQI assesses five primary air pollutants, which are ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen oxide, and airborne particles or aerosols.

Weather Effects on Air Quality

The quality of air can be impacted by wind and air pressure as they can transport pollutants from one place to another. Recently, we have observed the movement of wildfire pollutants from Canada to the northeastern region of the United States.

Usually, low-pressure weather systems result in moist and breezy conditions. Rainfall can cleanse the air by eliminating some of the airborne pollutants. Conversely, high-pressure weather systems may cause stagnant air. In the absence of wind, pollutants may accumulate over a particular area. Thus, urban areas with a high density of people tend to face air quality problems due to the naturally high production of pollutants.

When it’s sunny and hot, the amount of ground-level ozone can increase. This happens when the sun reacts with hydrocarbons and nitrogen oxides, which come from cars and some industries. When this happens, it can cause smog. Additionally, the humidity which is the amount of water vapor in the air can also affect air quality. When the air is humid, it tends to trap pollutants close to the ground, which makes it harder for them to disperse into the atmosphere.
