Why does northward-moving air deflect eastward driving mid-latitude jet streams?

💡 Explanation

Air masses conserve angular momentum; therefore, northward movement causes faster eastward speeds observed locally on the rotating earth. The Coriolis effect acts because, rather than flowing directly, the air deflects eastward, strengthening jet streams relative to their initial trajectory, rather than moving directly towards lower latitude.
