TEMPERATURE INVERSION!
Air moves in all directions. The horizontal transport of air is called "advection". When an air masses source region is warmer than the region in which it's blowing into, we simply refer to the processes as warm air advection. If winds are light and not a whole lot of mixing is happening in the vertical, then a temperature inversion can result, in essence trapping a cooler layer of air at the surface. Clouds will be unable to rise above the warmer layer, making the inversion visible if you have a high enough vantage point.
This shot, looking down at the inversion, was captured from Mt. Washington, NH. The tracks are those of the Cog Mountain Railway. I've never been on the train that goes up the mountain, but from what I hear, it's quite a thrilling ride! For more information check out here, http://www.thecog.com
