METEOROLOGY: AIR PRESSURE,
SYSTEMS, AND WEATHER MAPS
Air Pressure - ✔️✔️The force with which air is pressed down by gravity
High Pressure System - ✔️✔️A high pressure system has higher pressure at its center than the areas
around it
Low Pressure System - ✔️✔️a place where the atmospheric pressure is lowest compared to the
surrounding area
Intertropical Convergence Zone - ✔️✔️the region that circles the Earth, near the equator, where the
trade winds of the Northern and Southern Hemispheres come together
Coriolis Effect - ✔️✔️the apparent curve in the path of a moving object (like air or water) caused by
the Earth's rotation
Air Mass - ✔️✔️a very large body of air that has relatively uniform temperature and humidity
characteristics over a wide area
Pressure Gradient Force - ✔️✔️the force created by differences in air pressure over a distance, which
causes air to move from areas of high pressure to areas of low pressure
Isobar Map - ✔️✔️a weather map that uses lines, called isobars, to connect locations with the same
air pressure
