Which description best matches high pressure weather?

• A. Dry, sunny, and usually cooler
• B. Wet and stormy
• C. Cloudy and humid
• D. Foggy and misty

Answer: (A)

High pressure weather features sinking air that stabilizes the atmosphere and keeps clouds from forming. As air descends, it compresses and warms, which lowers relative humidity and leads to clear, dry skies. With little cloud cover, the sun shines during the day, but radiational cooling at night can make temperatures drop, so it’s often cooler than in stormier, cloudier conditions. That combination—dry air with sunny skies and cooler nights—is why this description best fits high pressure. Wet and stormy conditions come from rising air in low-pressure systems, while cloudy and humid or foggy and misty conditions involve more moisture and cloud formation, which high pressure tends to suppress.
