A 200 hPa streamline analysis illustrating the primary winter regime non-recurvature situation. Fine dashed line represents the 500 hPa 588 decameter contour. A 200 hPa streamline analysis of synoptic situation dictating north-ward movement of summer regime tropical cyclones. A 200 hPa streamline analysis depicting a synoptic situation under which a northward moving summer regime tropical cyclone would acquire a more westward component of movement. A 200 hPa streamline analysis depicting a synoptic condition under which a summer regime tropical cyclone would move toward recurvature.
Wind barbs are in knots.
Figure A.8 . A 200 hPa streamline analysis illustrating a synoptic situation conducive to reducing a summer regime tropical cyclone's northward component of motion. Tropical storm symbols indicate past cyclone movement and typhoon symbols indicate future cyclone movement. A 200 hPa streamline analysis illustrating a non-recurvature situation during a summer regime. Wind barbs are in knots.
