No, smog does not go away in the winter. It might seem as if the air is clearer during colder weather; after all, it smells crisper and is moister after a nice rain, but air pollution lingers in the atmosphere even through December, January, and February, which is why Smog Man Test and Repair is here in San Jose to make sure your vehicle doesn’t add to the emissions.
It Turns to Mist
When the weather turns cold, the exhaust from your car, SUV or truck turns into a mist. You see the steam and water coming out of your exhaust pipe in the morning or at night, and this is still the same exhaust that pollutes the air and causes smog. It just gets wetter, if you will, which might make it seem as if it has changed somehow.
It Isn’t Just Your Car
Air pollution in the winter actually increases due to other factors, as well. Your vehicle and industrial emissions tend to stay the same, but every time you build a warm fire in the fireplace, you add to air pollution. Fireplaces, fire pits in the backyard, and wood-burning stoves introduce additional smoke and carbon monoxide to the outdoor air.
Cold Air Keeps it In
Winter weather has a way of stagnating this pollution more than any other time of year. When it’s warm, such as in spring, summer, and the beginning of fall, warm air sits near the ground. When the warm air rises, it carries the pollutants with it. In the winter, cold air rests near the ground and it does not rise. This traps pollution and keeps it in place.
It Isn’t Just Outdoors
Indoor pollution can increase during the winter months, too, so keep this in mind. People keep their houses closed up during the winter to keep the cold air outside and the warm air inside. This causes an increase of dander, dirt, dust, pollens, and other allergens. It can also cause a dangerous increase in carbon monoxide, so replace your detector batteries.
