Schematic of possible pathways for coupling to troposphere for processes of (a) QBO-type (from tropical stratosphere) and (b) SSW-type (from extratropical stratosphere). Communication pathways: (1) extratropical stratosphere to midlatitude tropospheric jet; (2) tropical lower stratosphere to subtropical jet; (3) tropical lower stratosphere directly to tropical upper troposphere. Tropospheric feedbacks: (A) via extratropical dynamics; (B) via tropical dynamics
