← GeographyWhich environmental effect results when the subtropical jet stream meanders significantly?
A)Prolonged regional drought patterns emerge✓
B)Increased stratospheric ozone depletion develops
C)Enhanced thermohaline circulation downwelling starts
D)Accelerated glacial isostatic rebound occurs
💡 Explanation
Persistent Rossby wave formation from jet stream meandering causes standing anticyclones, leading to prolonged drought, because atmospheric blocking prevents precipitation; therefore, regional drought emerges, rather than ozone changes, oceanic circulation, or geological uplift, controlled by other mechanisms.
