1.   The air has cooled down a little now.

2.   As air cools, it becomes denser and weightier, eventually draining down mountains.

3.   As the air cools more water vapor condenses into flakes, resulting in a patchwork of snow depths that responds to the undulating terrain.

4.   As the air cools, more water vapor condenses into flakes, resulting in a patchwork of snow depths that responds to the undulating terrain.

5.   As the air cools, more water vapor condenses into flakes, resulting in a patchwork of snow depths that is shaped by undulating terrain.

6.   As the air cools more water vapor condenses into ice crystals, resulting in a patchwork of snow depths that responds to the undulating terrain.

7.   As the animal breathes, the outside air naturally cools the air supply.

8.   Because air cools the mower engine, that air needs to be clean.

9.   Despite the strong sun early this week, the air stayed perfectly cool to let the snow stand up.

10.   Dew point is the temperature to which air must cool for its moisture to condense and form dew.
