Near inertial gravity waves in a high resolution ocean model

Animation of the vertical velocity at 2 km depth from a year long run of the ocean model NEMO ORCA025 with output saved at 4 hourly mean intervals. The scale ranges from -60 (blue) to +60 (red) metres per day. The features which dominate the field are near inertial gravity waves, and are generated by variability of the surface wind field. The model experiment and animation were conducted and produced by Drs Adam Blaker and Andrew Coward, and was funded by the Natural Environment Research Council.
