sunshine and high temperatures not only contribute to the generation of particulate matter in the air but also facilitate the formation of ozone. In contrast, weather conditions that make people want to stay indoors (e.g., precipitation, low temperatures, and strong winds) are more conducive to fresh air and fewer pollutants in the atmosphere.
Favorable weather like sunshine, warmth, low humidity, and light winds encourage outdoor activity but also promote the formation and stagnation of pollutants, while less pleasant conditions like rain, cold, or strong winds tend to clean the air, with events like typhoons and heavy rainfall significantly improving air quality.
