Which weather outcome results when cold air masses obstruct atmospheric river streams over mountainous terrain?

💡 Explanation

Orographic lift intensifies precipitation because the approaching cold air forces moisture-laden air upward, across the mountain range, leading to greater condensation and rainfall in localized zones; therefore heavy snow develops, rather than alternative outcomes like solar heating or altered erosion.
