So you typically wont see a change in pressure from one extreme to the other in a matter of hours, but more over a time periods of days or weeks. And it's highly doubtful you'll feel the change in air pressure, but you'll certainly see the weather changes associated with pressure change.
The word apache comes from the Yuma word for fighting-men and from the Zuni word meaning enemy.. The Apache tribe consists of six subtribes: the Western Apache, Chiricahua, Mescalero, Jicarilla, Lipan and Kiowa. Each subtribe is from a different geographial region.
Since the Navajo and the other Apache groups are clearly related through culture and language, they are all considered Apachean. Apachean people formerly ranged over eastern Arizona, northern Mexico (Sonora and Chihuahua), New Mexico, west and southwest Texas, and southern Colorado.
