The seasonal cycle of submesoscale flows

WebbAfter the winter, the maximum of the upscale flux shifts to larger scales. Depending on the region, the kinetic energy reaches the mesoscales in spring or early summer aligned with the maximum of mesoscale kinetic energy. This indicates the importance of submesoscale flows for the mesoscale seasonal cycle. Webb12 nov. 2024 · This annual cycle suggests that over large regions of the world’s ocean, submesoscale-driven vertical transport could be out of phase with the seasonal nutrient requirements of phytoplankton.

Webb8 apr. 2024 · Submesoscale motions in the forms of filaments and eddies are present in the upper mixed layer during the whole annual cycle. Submesoscale motions show an obvious seasonality, in which they are active during the winter and spring but weak during the summer and fall. Webb1 feb. 2024 · The observations reveal a distinct seasonal cycle in upper-ocean PV, characterized by frequent occurrences of negative PV within deep (up to about 350 m) mixed layers from winter to mid-spring, and positive PV beneath shallow (mostly less than 50 m) mixed layers during the remainder of the year.
