A High pressure area (that makes an anticyclone) near a low pressure system (that makes a cyclone), makes air move from the high pressure to the low pressure to try to even out the pressures. The Coriolis effect causes the winds to spiral around. A big difference in pressure can make high winds. In some storms, such as hurricanes, typhoons, cyclones, or tornadoes, it can cause winds faster than 200 mph (320 kilometres per hour ). This can damage houses and other buildings, and can kill people.
