Webb13 juli 2024 · This seasonality is characterized by much smaller scales with larger amplitudes in winter (with Ro reaching values of order one) compared to summer, suggesting the presence of energetic submesoscales in winter. However, this seasonality has not the same intensity everywhere. Webbduces seasonal cycles of sea ice and upper-ocean properties that are consistent with observations (Section 3). In Section 4, we show how the development of small-scale flows under sea ice does not present the typical submesoscale soup ( Gula et al., 2014) charac- teristic of the midlatitudes.
