报告摘要:Wide-swath satellite missions, such as Surface Water and Ocean Topography (SWOT) and Winds and Currents Mission (WaCM), will quasi-concurrently observe two-dimensional sea surface height and velocity. Thanks to the high spatial resolution of these observations, both vortical and wavy motions will be well captured. A major challenge is to disentangle vortical and wavy motions in these snapshot observations. This issue has attracted much effort, but crucial progress remains to be made. Here, assuming that only a single concurrent snapshot of sea surface height and velocity is available, we pursue a dynamical approach for disentangling vortical and wavy motions. It is realized by noting that wavy motions do not carry potential vorticity which is thus ascribed to vortical motions. A proof-of-concept application to simulated flows suggests that the proposed approach is simple and efficient, and is particularly useful for disentangling wavy and vortical motions in observations by wide-swath satellite missions.
