The phrase "air sinking" is correct and usable in written English.
It can be used in contexts related to meteorology, physics, or discussions about air movement and pressure.
Example: "The phenomenon of air sinking can lead to the formation of high-pressure systems."
Alternatives: "descending air" or "falling air".
The cold front is identified by cold air sinking and replacing warmer air, which is forced upward.
The Brewer-Dobson circulation is characterized by warm air rising in the low-latitudes and cold air sinking in the high latitudes.
Conversely, the radio maps show ammonia-poor air sinking into the planet, similar to how dry air descends from above the cloud layers on Earth.
From the hospitality stop, mushers travel southwest on the Fortymile River in what is one of the coldest portions of the race, because of cold air sinking to the bottom of the river valley.
Brian McNoldy, a senior research associate at the University of Miami, said that across the Atlantic this season "you had air sinking through a pretty large depth of the atmosphere".
The night side, on the other hand, receives no solar radiation and is, therefore, radiatively cooled with the cooler air sinking and creating the reported downwelling.
As the air sank into the trough, the air warmed, and no clouds were formed.
At such times, the high-pressure air sinks faster than usual, gaining additional heat as it is compressed still further.
During the summer, cold air-conditioned air sinks to the bottom of the building and rushes out when swinging doors open.
In a high-pressure region, sinking motions are required to compensate for the divergence of air at the surface ( Figure 4-8 ); airair sinks it heats up by compression, relative humidity goes down, leading to sunny and dry conditions.
Meanwhile, kamikaze counterattacks from the air sank the light carrier Bismarck Sea and damaged other ships; and, though the U.S. flag was planted on Mount Suribachi on February 23, the isle was not finally secured until March 16.
