The wind off the Peru coast has influence on marine physical, chemical and biological processes, both in surface and sub-surface layers and impacts coastal sea currents, sea surface temperature, vertical mixing layer, transport and retention of larvae in the sea. Furthermore it influences the approach of oceanic waters towards the coast and in other cases it favors the extension of Cold Coastal Waters and Mixing Waters off the Peruvian coast through the coastal upwelling. Therefore, the intensification and weakening of coastal wind have a strong impact on environmental conditions and the ecosystem. In this work, satellite wind data obtained through the ASCAT (Advanced Scatterometer) scaterometer from a coastal strip up to 100 km (approximately 62 nautical miles) off Peru was used in five areas: Paita, Chicama, Callao, San Juan de Marcona and Ilo, during the period from March 21, 2007 to ...
