ABOUT ALTITUDE AND BAROMETRIC
PRESSURE
Generally, barometric pressure and temperature decrease as altitude
increases.
Barometer
Barometric pressure indicates changes in the atmosphere, and by monitoring
these changes you can predict the weather with reasonable accuracy. Rising
barometric pressure indicates good weather, while falling pressure indicates
deteriorating weather conditions.
The barometric pressures that you see in the newspaper and on the TV weather
report are measurements corrected to values measured at 0 m sea level.
