- A big tropical storm with strong winds - Low pressure and warm water are needed,
- Wind power can be superior to 120Km/h
• What is a Hurricane ?
•Remote sensing via satellites provides to the scientists to forecast and modelize these natural phenomenon

Conclusion
Remote sensing can be used to investigate :
-biological productivity in the oceans
-marine optical properties
-the interaction of winds and currents, weather forecasting
-how human activities influence the oceanic environment.
Remote sensing has an important role in climate modelization
