Air always moves from high pressure to low pressure (like air escaping from a balloon). The different arrangements of these areas of pressure are shown on weather maps. Low pressure is associated with stormy weather, whereas high pressure is associated with clear skies. There are also "fronts" which are boundaries between two air masses of different densities (think cold air and warm air). Often these are associated with a rapid change in temperature. For example, a cold front has warm air before the front, and cold air after the front passes. The front itself usually has stormy weather.Hurricanes are low pressure systems and move in two ways: in a spiral and across the ocean.
Because the Earth is round and spinning, objects attempting to move in a straight line across Earth's surface will appear to veer off course. This apparent deflection is known as the Coriolis effect. In a hurricane the central low pressure pulls in air from all directions. However, the air is deflected around the center due to the Corlios effect, causing a swirling motion.
