Weather Tidbits: Smog
It’s all about smog in this Weather Tidbits. Smog is a combination of smoke and fog. Poor air quality is usually caused by smog which can actually happen year-round. Smog can happen during an inversion where rising air reaches warmer air from above and cannot rise further; that smoke and pollution remains trapped near the surface, especially if there is little to no wind. Inversions are more common in the winter; while smog in the summer involves chemical interactions between the sun, oxides & volatile organic compounds called photochemical smog. It is known to make the skies gray to brown. Smog has become common in big cities and it’s also harmful to humans, animals & plants.
