Mature Stage

When a tropical cyclone encounters favorable conditions in the ocean and atmosphere, it may progress to the severe cyclone stage, which is the most hazardous phase.

About half of all cyclones reach this stage. During this phase, the cyclonic circulation and strength of the winds intensify significantly. Satellite imagery shows that the cloud fields become more organized and symmetrical, with a distinct circular eye at the center.

The severe cyclone stage typically lasts for around a day, during which time the cyclone reaches maximum intensity, unless it continues to encounter highly favorable conditions.
