← GeographyWhich atmospheric effect increases when high orographic relief disrupts Hadley cell circulation?
A)Strengthened subtropical jet stream✓
B)Increased surface ocean salinity
C)Weakened polar vortex stability
D)Enhanced thermohaline circulation rates
💡 Explanation
A strengthened subtropical jet stream occurs due to increased baroclinicity which arises from the disruption of Hadley cell air mass flow over substantial orographic features; localized temperature gradients sharpen because of disrupted airflow, therefore jet stream strengthens, rather than other widespread effects.
