| | Thermal Inversions (Site not responding. Last check: 2007-10-20) |
 | | One thing I do know is that in eastern Colorado, inversions are perpetually a problem because they tend to keep the smoke from people's chimneys close to the ground, as well as holding in CO from cars, and it is generally unpleasant. |
 | | The inversion layer may extend from a few feet to several hundred feet above the surface, and is usually dispersed by the next day's solar heating (there is your convection). |
 | | The inversion was able to persist for a couple of reasons: there was a big, slow-moving high pressure area present, and there was a persistent fog, which prevented sunlight (which was weak anyway, since it was late autumn) from reaching the ground and heating it to produce convection. |
