Which mechanism causes intense focused precipitation as an atmospheric river interacts with coastal mountain ranges?

💡 Explanation

When an atmospheric river encounters a mountain range, orographic lift forces the moist air upwards, adiabatic cooling occurs because expansion in lower pressure causes the temperature to drop, increasing condensation and heavy precipitation. Therefore orographic lift is the primary mechanism, rather than upwelling, suppressed convection, or stabilizing radiative forcing.
