TABLE 5.
The surface eddy horizontal length scales (LKE) (units in km) associated with geostrophic surface kinetic energy computed over the final year of the 1/25° global HYCOM simulations and 1/12° Atlantic HY-COM simulations. The domain chosen for the entries listed here is the North Atlantic between 59.3° – 39.3°W and 19.6° – 39.6°N, very close to the region shown in Fig. 1.
