formation

• A tropical storm forms over warm ocean water (at least 26.5°C), which heats the air above, causing it to rise and form clouds. As the air cools and condenses, it releases heat, fueling the storm. Low wind shear helps the system stay organized, while the Coriolis effect makes it spin. As more warm air is drawn in, the storm strengthens. When wind speeds reach 39 mph (63 km/h), it becomes a tropical storm.
