← GeographyWhich 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.
