← GeographyWhich effect occurs as atmospheric river streams encounter steep coastal terrain?
A)Orographic lift and precipitation increase✓
B)Enhanced radiational cooling and sinking
C)Decreased convective uplift diminishes rainfall
D)Stable temperature gradient inhibits condensation
💡 Explanation
Orographic lift forces air upwards, enhancing condensation, because the air is forced to higher altitudes; this leads to increased precipitation. Therefore, rainfall substantially increases rather than decreasing (C), as radiational cooling (B) or temperature stability alone couldn't counteract the intense uplift.
