ABSTRACT
Anticyclone is the name given to a system of high pressure (Figure 55). The wind circulation around this system will be clockwise in the northern hemisphere and anti-clockwise in the southern hemisphere. Anticyclones are associated with small pressure gradients and consequently light winds. As they are areas of subsidence, rainfall is unlikely. They may be classed as either cold or warm and each of these may be either permanent (long lasting) or temporary.
