The night sky looked as it should, illuminated by countless stars, and an air of peace descended.

As the air descends the lee side of the mountain, it warms and dries, creating a rain shadow.

Now, a tense air of expectancy has descended on this city.

The cool air descends and accelerates as it approaches the ground.

The air is descending from above, which has the effect of reducing angle of attack.

Opaque air had descended to the horizon, hills beyond the housetops of the town.

As night falls just about seven weeks from today, an air of mandatory gaiety will descend on the city.

As the air descends it heats up at a rate of 1DegreeC/100m.

Cool air descended from them, and washed invisibly along the floor.

His worth, his actions, and majestic air, A man descended from the gods declare.
