Earth:Air basin

From HandWiki

An air basin is a geographical region with commonly shared air masses,[1][2] such as an area within a ring or partial ring of mountains, in which winds generally mix and stay, although air does pass in and out of basins.[3] It describes a land area with generally similar meteorological and geographic conditions throughout.

California is divided geographically into 15 air basins for the purpose of managing the air resources of the State on a regional basis.[4]
