Study of the trajectories of extratropical cyclones formed in the Antarctic Peninsula region during spring time
The ocean is increasingly seen as a vital component of the climate system. Through the surface of the ocean, exchanges with the atmosphere of heat, water, gases, particles occur. Extratropical cyclones (EC) transfer momentum into the superficial layers of the ocean due to the friction of the wind, i...

The ocean is increasingly seen as a vital component of the climate system. Through the surface of the ocean, exchanges with the atmosphere of heat, water, gases, particles occur. Extratropical cyclones (EC) transfer momentum into the superficial layers of the ocean due to the friction of the wind, in addition they distribute heat and humidity from low to high latitudes. These systems are centered in the ocean-atmosphere interaction and climate in South America. In the Southern Hemisphere, the area between southern Brazil and the Antarctic Peninsula (AP) (30 ° S to 70 ° S) is described as one of the most favorable for the formation of cyclones because of the existence of strong temperature gradients between the ocean and the above surface air layer and also pre-existing baroclinic instabilities.
