- 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
