anticyclone
- Sinônimos
- high
- high pressure area
- Definição1
- Atmospheric circulations that rotate clock-wise in the Northern Hemisphere and anticlockwise in the Southern Hemisphere. Anticyclones are areas of high pressure and are generally associated with light winds and good, stable weather. On weather charts, anticyclones are depicted by circular isobars with the high pressure at the center.

- Definição2
- Region of the atmosphere where the pressures are high relative to those in the surrounding region at the same level. It is represented on a synoptic chart by a system of isobars at a specific level, or of contours at a specific pressure, which enclose relatively high values of pressure or contour height.

- Nota adicional1
- With respect to the relative direction of its rotation, it is the opposite of a cyclone. Because anticyclonic circulation and relative high atmospheric pressure usually coexist, the terms anticyclone and high are used interchangeably in common practice.
- Contexto
- Over Europe there was a powerful anticyclone of 1.041 mb producing a wind from the first quadrant at all levels towards the Cantaban Mountain Range, generating stationary clouds over the coast.
