I just don't understand this concept, what are they what do they do, when do they apply. Just give me a run about.

Hot air rises in the morning basically due to the sun rising. As the sun sets in the evening the air cools and falls downward. That is why I think I have better luck in the morning because your scent is being pulled upward. In the evening if you are hunting from a treestand your scent begins to pool around the base of the tree because of the downdraft. They apply everyday in my opinion. You can feel it. This is my understanding. If that is not right, someone else explain it.

Crazy's right... the impact for the deer hunter is critical if you set up on a ridge or on a flat top adjoining a large ridge... in near calm conditions, slight breeze at 15' might be going one way, but the air movement at ground level as evening sets in will be from higher elevation to lower elevation, i.e. scent is going to be pulled downhill...
Reverse that in the morning, as the sun hits the ground and warms the cover, the air will move UPHILL...

You can tell when the thermals are at work on a calm day as the tree leafs will start to slightly flutter in place vs. directional movement from a predominate breeze & wind.
On foggy mornings you can really see the thermals at work as the fog starts lifting from the ground.
I have a short length of frayed floss on my deer guns & bow to watch what the thermals, breezes, & winds are doing while hunting.

Another trick similar to Deertrack's is to find some milkweed seed pods and pull out the silky seeds inside... I carry a bunch of silks in an old film canister, and when I want to test the wind from a stand, pull that out and release some silks... if you're worried about spreading milkweeds, you can pull the seed loose from the silks in advance...
Some guys drill a little hole in the canister top, but I've found it easier to just take the lid off than trying to get the silks to repeatedly pull through a hole like that...
There are commercial products that do somewhat the same thing, but this method is free, and one milkweed pod will supply you with enough silks for several seasons...

Yeah it really comes into play hunting elk. Camp at the top of the mountain and hunt downhill in the mornings and visa versa in the evenings..Thermals are in play everyday, then add wind, humidity and other variables and scent dispersion is effected differently on a daily basis depending on each days unique conditions...The details are what seperate the Men from the boys...You'll notice the guys who take big mature deer consistently pay special attention to the minute details...

I take an old small baby powder bottle and dump it out and put baking soda in it. And squeeze it.

Great Idea Deertracks, Never thought about tying something so light to my bow? I tried it this Morning and worked Great, even with the calmest wind.......

so, i guess i understand a little but how are you suppose to hunt at night when you scent is going down then, what affects it anything? Is it worse when it's hot or cold, ?/

so, i guess i understand a little but how are you suppose to hunt at night when you scent is going down then, what affects it anything? Is it worse when it's hot or cold, ?/ I think you are better hunting close to the ground in the evening, but I don't always do it. Of all of the senses, a deers nose is probably its best defense. I have read that a deer can smell 100 times better than a bloodhound. Think about that. It has been said that a bloodhound can trail a scent that is two weeks old. About the best things you can do are to try and keep the wind in your favor, be as scent free as possible, don't lay any scent down and hope for the best. Thermals are basically a breeze moving up in the morning and down in the evening. This is just my line of thought, so take that for what its worth. |

If you have a wind of 5 mph or greater, then thermals don't come into play much, if at all... you're working with the dominant wind direction at that point...
It's when things get really calm, and you're hunting on elevated/angled ground that they would come into play as the sun gets near the horizon... on level ground, I would think you'd just get a boundary layer between cooler air at ground level and warmer air higher up without much exchange.

THERMALS ARE SIMPLE AS THE AIR WARMS IN THE AM it rises remember warm air rises in the pm as the air cools it sinks so in a hunting situation in hilly ground in the am hunt below you the warm air(thermals) will rise carrying your scent above you with the rising Thermals in the pm the cooler air will sink ,so hunt above you see now
