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.
According to the Apache Software Foundation: The name 'Apache' was chosen from respect for the Native American Indian tribe of Apache, well-known for their superior skills in warfare strategy and their inexhaustible endurance. It also makes a cute pun on a patchy web server -- a server made from a series of patches -- but this was not its origin.
