Subsidence
Encyclopedia entry from: The Gale Encyclopedia of Science
...cyclone, is not always present. Subsidence, or sinking of air, may happen instead, forming an area of high pressure, an anticyclone. Large scale subsidence occurs when air several thousands of feet overhead is denser than the surrounding air. This denser...
