How does high atmospheric pressure typically affect local weather?

• A. It leads to overcast skies and precipitation
• B. It usually brings clear, calm weather
• C. It causes severe storms
• D. It has little effect on weather patterns

Answer: (B)

High atmospheric pressure is generally associated with descending air, which inhibits cloud formation and moisture accumulation in the atmosphere. This process typically results in stable weather conditions, leading to clearer skies and calmer winds. Under high-pressure systems, the air is relatively dry, and any moisture that might have been present at lower altitudes is often subsided or dispersed, which prevents cloud development and precipitation. This is why high-pressure systems are often linked with fair weather, as they tend to create ideal conditions for clear skies and pleasant, stable atmospheric conditions.
