Which cloud type is typically associated with steady, widespread precipitation?

• A. Cumulus
• B. Cirrus
• C. Stratus
• D. Stratiform

Answer: (D)

Steady, widespread precipitation comes from layered clouds that blanket a large area. These stratiform clouds form a broad, horizontal deck, letting moist air rise and condense over wide regions, which results in continuous rain or drizzle rather than scattered bursts. The atmosphere here is generally stable, so the precipitation is steady and covers a large area. Cumulus clouds are vertically developed and produce showers or thunderstorms that are more localized and variable. Cirrus clouds are high and wispy and usually don’t bring significant precipitation. Stratus clouds are a low, uniform layer that can bring light drizzle, but the broad, persistent rain characteristic of widespread rainfall is best described by stratiform.
