Fog In The Night

FTLComm - Tisdale - Friday, June 29, 2001

When the temperature reaches the point where the humid air reaches its maximum ability to hold the water vapour the invisible water vapour condensens and we call it fog. Essentially we see it all the time and call it clouds but in this case the cloud forms right on the surface. Last night just after midnight the wet supersaturated air fell to dew point and we had inky fog. I have tried to get pictures of this before but have been unsuccessful. This time I was lucky and you can see the air illuminated by the street lights as the air is now filled with visible water vapour. The fog was so dense that I thought I would try a flash image and indeed the light from the flash reflects off the dense water filled air in this picture.
