the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer. Many models include a manually set needle which is used to mark the current measurement so a change can be seen. -
Page 5: Absolute Vs. Relative Pressure
• Steep drops of 6-10 tenths mbar within 4-5 hours period indicates coming rain and/or storm with strong winds. 4.3 Absolute vs. Relative Pressure To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at if located at sea-level) is generally higher than your measured pressure. -
