During the thermal reversal, the temp of the cooler air becomes too warm to continue falling. It reaches a point of nuetral buoyancy and completely stops flowing for several minutes, until the sun warms the air a couple of degrees higher and causes the air to begin rising. These occurances happen normally twice a day.. once in the am and once in the pm. Unless on a cloudy or damp day where air becomes to heavy.

The interesting thing about the phenom.. is it moves the deer. Causes many deer to get up and get to another bedding area. One where they can take some advantage of the new thermals.

Now it doesn't always move them. But it often does. There's alot of other variables to consider as well.

But I've learned to recognize the phenom in the morning.. and get ready for movement. I do have a harder time recognizing it in the evening however.

But its interesting to me.
