Above the Inversion in the Columbia Basin

I was up on the southern edge of the Columbia Basin looking down on the inversion. Clear nights and  a high pressure ridge over Washington has caused temperatures to drop and cold air to settle into the basin with dense fog forming along the boundary of the cold air below and the warm air above. This is not an uncommon phenomena within the Columbia Basin. I was up on the ridge line of the Horse Heaven Hills at the southern edge of the basin and enjoyed warm sun while looking down on the fog covered basin.

There was some breeze over the ridge line and the wind turbines were turning. I heard no noise whatsoever from the wind turbines, but I could hear the train sirens from below the fog located at least 12 miles distant. Simply an anecdotal and striking how noise travels in unexpected ways.
