Barrier Layers in a High-Resolution Model in the Eastern Tropical Pacific
[20-Nov-2020] Bingham, F., Li, Z., Katsura, S., and Sprintall, J. Barrier layers (BLs) play an important role in regulating the transfer of heat, momentum, and freshwater across the ocean's surface and into the ocean interior. BLs are shallow layers near the ocean surface where vertical density change is controlled by salinity. These layers appear intermittently in the tropical ocean and can vary in thickness. Previously, there have been gaps in understanding about the relationship between surface flow and barrier layer thickness. This study looked at two BL events in the Eastern Tropical Pacific (ETP) to investigate this using a numerical model.
