Barometric pressure typically does what with weather?

• A. Usually goes up in good weather and down in bad weather
• B. Remains constant regardless of weather
• C. Goes down in good weather and up in bad weather
• D. Is unrelated to weather

Answer: (A)

Barometric pressure reflects the large-scale air masses in the atmosphere. When a high-pressure system dominates, air sinks, the weather tends to be clear and stable, and the barometer rises. When a low-pressure system approaches, air rises, clouds form, and storms are more likely, causing the barometer to fall. So, in general, good weather corresponds with rising pressure and bad weather with falling pressure, making that statement the best description of how barometric pressure relates to weather. Pressure doesn’t stay constant, it changes with weather, and it’s not unrelated to weather; the opposite pattern would not fit typical conditions.
