Weather. Chapter 24. Air Masses. Differences in air pressure are caused by unequal heating of Earth’s surface. Heated equatorial air rises & creates a low-pressure belt. Cold air near the poles sinks & creates a high-pressure centers. Differences in air pressure creates the wind patterns.
Barometers = measures atmospheric pressure
Thermometer = measures & indicates temperature
Wind vane = used to determine direction of wind
Anemometer = used to
measure wind speed
