USATODAY.com Latest News ... How a barometer measures air pressure ... The centers of storms are areas of relatively low air pressure, compared to pressures around the storm. High air pressure generally brings good weather. Keeping track of how the pressure is changing is important for forecasting the weather.

Answer: Ambient pressure is a sensor reading from the unit. Normalized/barometer pressure is the unit's best estimate of locally reported sea-level pressure for your location. This estimated pressure does not compensate for humidity or temperature. ... Q. What is the difference between ambient and normalized/barometer pressure?

Answer: Because the barometer/normalized pressure is calculated based on ambient pressure and elevation, changing the elevation will change the barometer/normalized pressure. ... Q. Why does the barometer/normalized pressure change when I calibrate the altimeter with a known elevation?
