Gyres Flashcards
ocean currents
masses of ocean water that flows from one place to another
surface currents
wind driven currents more water hrizontally and occur primarily in the oceans surface waters
deep currents
dense waters that sinks and spreads slowly beneath the surface
subtropical gyres
center of the gyre coincides with the subtropics at 30 degrees north or south latitude
eqatorial currents
currents that travel westward along the equator and forn the equatorial boundry current of subtropical gyres
western boundary currents
west side of ST gyres
Northern Boundary Currents
north of ST gyres
Southern boundary urrent
south side of ST gyres
Eastern Boundary currents
East side of ST gyres
Equatorial countercurrents
straight horizontal currents
subpolar gyres
gyres that rotate opposite the adjacent subtropical gyres
gulf stream
high intensity western boundary current of the NOrth Atlantic that flows east
El Nino
flowing water current that develops around ecuador
upwelling
vertical movement of cold, deep nutrient rich water to the surface
donwelling
vertical movement downward
