How to Produce Storm Intensification
Fig
• Cyclone intensification is related to the southward moving of cold air to the west of the cyclone and the northward moving the of the warm air to the east of the cyclone.
• These movements cause an upper-level deepening of the trough west of the low and an intensification of the ridge east of the low.
• As a result, the curvature between the trough and the ridge increases, and the jetstreak at the base of the trough enhanced due to a stronger pressure gradient.
•These changes intensify the divergence aloft, leading to an intensification of the surface low-pressure center.
