Which risk increases for alpine glaciers facing foehn wind patterns?

A)Accelerated glacial ice ablation
B)Increased accumulation zone ratio
C)Enhanced crevasse formation rate
D)Reduced equilibrium line altitude

💡 Explanation

Glacial ablation is accelerated by orographic lift and adiabatic wind warming induced by the rain shadow effect; this causes increased energy transfer via convective heating, because the foehn wind forces warm, dry air, downward rather than trapping cold air and moisture.
