Abstract

The Seasonality of Surface-Balanced Motions at Diurnal Scales in the Eastern Boundary Currents is Highlighted by Dynamic Filtering

The majority of the kinetic energy budget and the majority of the vertical velocity in the ocean are captured by Balanced Movements (BM) and Internal Gravity Waves (IGW). It is difficult for BM to contribute to both problems at time periods of less than a day since BM are IGW hidden. We described the implementation of a dynamical filter to research the BM regime that distinguishes the two types of motion. A high-resolution global simulation was employed in this work to examine the winter and summer seasons, the Eastern Boundary Currents. Our findings support the recovery of BM dynamics over short time scales with emphasis on the diurnal cycle in winter is feasible due to local stratification, which precludes a considerable vertical excursion of the, and its damping in the summer. Our filter opens up new avenues for a more precise assessment of any tracers' vertical exchanges at any level of the water column. Additionally, it could be a useful tool for research on wave-turbulence interactions in computer-simulated oceans
