Temperature inversion

Inversion:  Atmospheric condition where a layer of colder air near the ground gets trapped under a layer of warmer air.  The pollutants ( which normally disperse over a wide area) remain locally confined due to inversion. 

Really, one of the more unpleasant weather patterns we get stuck in.  The weak October sun couldn't break through the murk yesterday.

Meanwhile, up at Paradise (literally) near Mt. Rainer, a blue bird day with almost empty parking lot.  My brother Dave drove up there yesterday and took this picture. 

That's the rising full moon, giving a nice Halloween effect last night.  Anyway, rain comes back on Thursday, bringing us a fresher sort of grey.  In the meantime, hazardous driving conditions and flight delays at SeaTac.  Good day to stay close to home and revive some neglected winter hobbies.

Atmospheric condition where a layer of cold air nearer to the ground gets trapped under a layer of warm air. The air pollutants (which would normally have dispersed over a wide area) remain locally confined due to inversion. In cold countries, morning school openings are often delayed to protect school children from this concentration of polluted air. Also called temperature inversion.
