How does a barameter have to to with static electricity?

Answer 1

The connection goes like this:

• The barometer is a device for measuring air pressure
• As a storm approaches your location the reading on barometer will drop
• The storm may be a lightning storm
• Lightning is static electricity

Answer 2

A barometer measures air pressure, which can be affected by static electricity. Changes in air pressure can create conditions conducive to static electricity buildup. High static electricity levels can be generated in low-pressure weather systems, while grounded conductors can help dissipate static electricity in high-pressure systems.
