HIGH PRESSURE SYSTEM/ANTICYCLONE. Is an area which has a higher air pressure than the surroundings (the value of the isobars decrease with distance from the centre). Winds within high-pressure areas flow outward from the higher pressure areas near their centers towards the lower pressure areas further from their centers. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward.
For this reason, within an anticyclone, at high altitude we have air converging, then descent of air within the anticyclone (subsidence) and divergence at the surface.

• Typical weather in an area under the influence of a High-Pressure is clear skies due to the sinking motion of air (subsidence), lighter winds than around a Depression and reduced chance of precipitation.
