Fog on the Fields
June 01, 2001
Across the road and down the hill you can see a ghostly pall of white moving across the fields. As the mid-day sun breaks through the morning clouds, it warms the dark moist soil, evaporating water and releasing it into the air. Normally the process is invisible, but a cold east wind off of Lake Michigan has dropped the air temperature below the dew point, and the water vapor condenses to form the low ground fog seen in the upper right of the image.
