How can you remember the difference between low and high pressure?

• A. low = lousy weather; high = happy weather
• B. low = fast weather; high = slow weather
• C. low = warm weather; high = cold weather
• D. low = coastal weather; high = inland weather

Answer: (A)

Understanding how air pressure affects weather is the key idea. When air pressure is low, air tends to rise; as it rises, it cools and moisture condenses into clouds, often bringing rain or storms. When air pressure is high, air sinks, which suppresses cloud formation and leads to clearer, drier conditions. A handy way to remember this is the simplest pairing: low pressure = lousy weather, high pressure = pleasant or clear weather. The other ideas don’t line up with what pressure does to the atmosphere—pressure isn’t about speed or warmth by itself, nor is it determined by proximity to coasts versus inland areas.
