An animation of three-dimensional current velocity in the North Atlantic, where velocity ranges from 30 centimeters per second, shown in blue, to 200 centimeters per second, shown in red
Three-dimensional General Circulation Models divide the ocean into a rectangular grid with layered vertical columns. This North Atlantic model uses a 1/6 degree grid with 37 layers. It captured 30 years of velocity, sea-surface temperature, and salinity. The model realistically separates the Gulf Stream from the Florida coast. A feature as small as the Gulf Stream had not appeared in lower-resolution models.
Video slate image reads, "North Atlantic Ocean Current Velocity This North Atlantic model uses a 1/6 degree grid with 37 layers. The complete model captured 30 years of velocity, sea-surface temperature, and salinity."
