What does the symbol H stand for on weather maps?

• A. Low-pressure system
• B. High-pressure system
• C. Rainstorm
• D. Clear night

Answer: (B)

On weather maps, the symbol H marks a high-pressure system. High pressure means air is sinking as it moves downward, which suppresses cloud formation and tends to bring clear skies and lighter winds. The H is placed at the center of that high-pressure area to indicate where the pressure is highest. In contrast, low-pressure areas (marked with L) involve rising air and are commonly associated with clouds and precipitation. A rainstorm is not indicated by H; it’s more connected with low pressure or fronts. A clear night isn’t a specific symbol on weather maps—the map conveys pressure systems, fronts, and precipitation, while the general outcome (like a clear night) follows from the prevailing high-pressure conditions.
