Which outcome results when mountain ranges deflect upper-level wind streams?

💡 Explanation

Orographic lifting and deflection introduce disturbances into atmospheric flow, initiating Rossby waves because the change in vorticity results from the disturbance modifies the jet stream's path; therefore, Rossby waves manifest rather than pressure changes caused by surface heating.
