My respiratory system has been feeling the effects of a temperature inversion in the Salt Lake Valley – a phenomenon that occurs frequently in the winter months here. Many of my studnets have been complaining of an exascerbation of their asthma symptoms.
In inversion occurs when a high pressure system develops and just sits over the area, trapping the smog and creating more polluted and still air until a storm comes along and blows it away.
Some days it gets so bad that people are asked not to drive or burn wood stoves.
They Department of Environmental Quality‘s website today reports that the air is “green” or “heatlhy”.
