Weather can vary from day to day and place to place. One of the major factors that affect this is AIR
PRESSURE. Highs and Lows are areas where the air pressure is higher or lower than the surrounding
area. Weather maps represent these areas as an H for high pressure and L for low pressure. As these
changes in high and low pressures move across the country they bring changes in weather. Generally
High pressure brings nice weather and Low pressure brings stormy weather and clouds.
Each pressure system (High and Low) have their own characteristics associated with them. On the back
of this page you will find characteristics of each pressure system, High Pressure and Low Pressure.
Use the characteristics of each High and Low pressure and the diagram below to answer the questions.
