Guidelines for using the pressure systems worksheet. A pressure system is an area of the earths atmosphere that has a particularly high or low pressure compared to the air around it. Because the converging air is wet and full of excess energy, it expands and cools as it rises, creating the clouds and heavy rainfall that are prominent throughout the area. For example, the abundance of energy reaching the equator produces hot humid air that rises high into the atmosphere. A low pressure is the result of convergence air flowing towards it and a high pressure is the result of divergence air flowing from it.
