| Air Flow & Transported Pollution | |
|
Pollutants are carried from the ocean towards the mountains on an almost daily basis during the summer months. |
|
Streams of air carrying emissions mix with locally generated
pollution from automobile traffic, small engine exhaust, industry, and agriculture
and they react in the area's abundant sunshine to create ozone, commonly called smog. |
|
A warm inversion layer acts like a blanket on the smog layer, preventing it from dissipating higher in the atmosphere. Because of high pressure, the region regularly experiences these thermal inversions. The regions low areas, which are nearly at sea level, often fill at night with cool heavy air underneath a layer of warmer air. The cool air layer grows through the night reaching up to 3000 feet thick. |
