← GeographyWhich effect results when a high pressure system descends?
A)Increased atmospheric stability and subsidence✓
B)Intensification of prevailing surface winds
C)Enhanced El Niño/La Niña oscillation cycles
D)Amplified formation of upper-level cyclones
💡 Explanation
High pressure systems cause atmospheric stability and subsidence because air descends and warms via adiabatic compression, inhibiting cloud formation; this suppresses uplift rather than promoting circulation, therefore favoring clear conditions rather than other unstable weather patterns.
