How does weather or climate affect air pollution?

How does the weather affect air pollution?

Temperature, Sunlight, and Humidity. Air temperature affects the movement of air, and thus the movement of air pollution. … The warmer, lighter air at the surface rises, and the cooler, heavier air in the upper troposphere sinks. This is known as convection and it moves pollutants from the ground to higher altitudes.

How geographical and climatic conditions affect the local air pollution?

The climate influences temperatures, cloudiness, humidity, the frequency and intensity of precipitation, and wind patterns, each of which can influence air quality. … These changes would in turn modify emissions (depending on the fuel source) and thus further influence air quality.

How do local weather conditions affect pollution?

For example, sunshine, rain, air temperature and wind can affect the amount of air pollution present: Sunshine – makes some pollutants undergo chemical reactions, producing smog. Rain – washes out water-soluble pollutants and particulate matter. Higher air temperatures – speed up chemical reactions in the air.

How does climate change affect the atmosphere?

The atmosphere is warming. We’re starting to feel the effects. A warming atmosphere affects more than just air temperatures: while heat waves and droughts are becoming more common and intense, rainstorms are also becoming more powerful, sometimes provoking dangerous floods.

Does rain decrease air pollution?

Rain might ruin a picnic, but when it comes to air pollution, it can actually be a really good thing. This is because, on rainy days, most of the common air pollutants and pollen in the air are washed away, helping to increase the quality of the air.

How temperature affects weather and climate?

Higher temperatures mean that heat waves are likely to happen more often and last longer, too. … Warmer temperatures can also lead to a chain reaction of other changes around the world. That’s because increasing air temperature also affects the oceans, weather patterns, snow and ice, and plants and animals.
