2.1 Anticyclones (high pressure). Anticyclones tutorial. Areas of sinking air which result in high pressure are called anticyclones (the opposite to an anticyclone is the cyclone or depression, which is covered next).High pressure systems have small pressure gradients (ie the air pressure doesn't change rapidly). This means that the winds are gentle..1 Anticyclones (high pressure). Anticyclones tutorial.
