Pollution tends to be worse in the morning due to a combination of factors, including reduced wind and the accumulation of particulate matter.
Researchers have concluded that particulate matter concentrations are higher in the morning and at nighttime. Additionally, there tends to be less wind at night, allowing air pollutants to settle closer to the ground. Here’s a breakdown:
Factors Contributing to Higher Morning Pollution
| Factor | Description |
|---|---|
| Reduced Wind | Less wind overnight means pollutants don't disperse, leading to higher concentrations near the ground. |
| Particulate Matter Accumulation | Studies show particulate matter concentrations are generally higher in the morning. |
In summary, the combination of lower wind speeds at night and a general increase in particulate matter concentrations results in higher pollution levels in the morning.
