Which impact results when persistent high pressure disrupts Hadley cell atmospheric circulation?

A)Extensive, prolonged regional drought develops
B)Increased oceanic upwelling of nutrients begins
C)Localized increases in magnetic field strength
D)Accelerated permafrost thawing on Arctic tundra

💡 Explanation

If high pressure persists and suppresses convection within a traditional Hadley cell area, regional drought is likely because subsidence prevents cloud formation associated with rainfall; this is atmospheric stability, rather than the instability causing precipitation. Therefore drought occurs, rather than upwelling shifts.
