doing work with video's, LOL

Sure, but how long does it take to cool off to ambient temperature? Not very long if I was to guess. W/out the aid of body temperature to keep it @ 98*, it's gonna cool off rapidly. Then that law does not apply. If there is a sinking thermal, you're busted. Your scent is gonna cool off and sink w/ the thermal. My way of thinking anyway.

Tony, yes, it plays a large part in my hunting.I LOVE hunting ridge tops on high pressure mornings. That thermal shoots almost straight up. I use those wind puffers to see what the thermals are doing, and it's usually pretty interesting.

Duke ...... is it like it sounds? If not, what is it?

Its when the girls on top. .

Correct Don ...... That is typically a night time occurance

Exactly why I started this thread .... I think it is one of the most overlooked "advantages" that we can have ..... I am with ya, bro..

Man Gary .....watch that combover

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.

Don:

What does a wind puffer have to do with the thermal of your scent.....if the air around you isn't the same temperature as the scent/air you're emitting?

When I say I use thermals to my advantage.....I'm talking about wind speeds of less than 10mph. Anything over that....I figure it isn't worth it.....OR...I'm losing my advantage (in the example of a less than favorable wind).

Less than 10mph.....(and the closer to 0 the better) I think I can use thermals to my advantage. What the air coming off ME does....and the air 10' beside me is doing, though......I think are two different things. If they aren't.....then I see no advantage to what I'm doing.

I don't think air comes off of you. Your body may be warming the air that is right next to it but the air 5'-10' beside you is going to dictate where your body heat goes. 98 degree body heat is not enough to generate an updraft.

Breaking this down......

Warmer air rises....and colder air comes to the ground.

Now I may learn something here.....so here goes.....

HOW do you know if you're in an area (using the mushroom as an example) that has air rising......or if you're on the outer edge and your actually in an area that is being pushed down?

And.....while we're at it.....Is this sctually occurring all the time? Don't the layers remain intact.....and remain layers until they are heated and rise?

And if that's correct....and you're in a tree 20+'.......how is your scent going to be coming down as the air is heating up (on a cold morning)?
