Temperature I am 90% sure. Don't know if this is right tho.
There are many factors that determine the daily fluctuation of air temperature just above the ground. One factor is the wind.
Cool Air! As the heated air rises the heated air starts getting cool. This is because the higher the air is the colder it gets. Then the heated air will be replaced with cold air. As the cold air then comes down near the ground the cool air will become heated because of the sun. Heated Air - Cool Air - Cold Air And On And On It Goes
Dew forms when the air just above the ground is cooled to its dew point (a temperature at which the water dissolved in the air comes out of the air). The air above the ground is cooled because the ground radiates heat into space. If there are clouds overhead the clouds reflect the heat back to the ground so it does not cool and o dew forms. If it is windy then the air just above the ground keeps on getting mixed with the air higher up and the air does not cooled to the dew point and no dew forms. Thus to form dew you need a still clear night.

Land Breeze
When sunlight strikes the earth, the ground is heated, warming the air above it, this air expands, reducing its density and it is forced upward by the denser surrounding (colder) air. While the ground continues to be heated a continous column of heated, rising air is produced.
The air is hottest just above the ground.

Radiation Inversion
heated air rises, so it's usually just air w/some type of heater above basket
As air (unconfined), is heated its volume increases, and its density decreases. That makes it lighter (per volume) than it was. Warm air will rise above colder air, and in essence, float on top of the colder air.

in a upward motion
because its evaporating
