Scent question
Someone told me the other day that you are less likely to be smelled during the morning because the ground is heating up and that warm air being released lifts your scent up. I'm having a hard time believing this, if you've ever taken chemistry you know that an object releases heat when it is cooling off, not when it is getting warmer. I would think the evening would be better. Either way, the wind can swirl around and do all kinds of funny things to carry your scent back down. Opinions?

RE: Scent question
Yes, that is correct.
Inthe morning as the air is slowly heated, the air tends to rise, taking your scent with it.
Contrary, in the afternoon, before sunset, as the day cools down, the opposite happens.

When the ground is warming up the heat is going into the ground. when the ground begins to cool down the heat is leaving the ground. its all about transfer of energy.

Without getting too technical:
Air contains molecules that move or agitate. This movement or agitation is greater as the temperature rises. This causes the mass of the air to expand. Although the total mass of a lump of air has not changed, the mass is more spread out and so any given cubic area of it will be lighter.
That's whythey use a "Hot air balloon" not a "Cold air balloon".
The heated air will bewarmer than the surrounding air and the balloon will rise.
Of courseswirling windscan have an affect on air and carry your scent down, but that wasn't the question.
And yes, I have taken Chemistry, I have a degree in it.
Let me put it this way, if you believe...bull81, you'll be wrong....

RE: Scent question
The reason warm air rises is because it is less dense (lighter) thancolder air.

RE: Scent question
BINGO!!! You nailed it on the head. In my profession we see this alot. I work for an Internet Service Provider in central Wi and we have wireless towers all over the place in central Wi. Once in a while we will have whats called the Ducting Effect. As the surface of the earth warms up it pushes the wireless signal up, thus making wireless connectivity go goofy for a while. Then as the day goes on and the day cools off, or the heat from upper atmospheredropsthe signal begins to drop to normal range and wireless connectivity begins working properly. You can think of your morning scents as a wireless connection and the ducting effect.This is why I do not use scents during morning hunts.
