    New definition of potential spicity by the least square method
    (John Wiley & Sons, 2018-10-16) Huang, Rui Xin ; Yu, Lu-Sha ; Zhou, Sheng-Qi
    A differentiable function whose contours are orthogonal to potential density (σ) contours does not exist. However, such a function, called potential spicity (π), can be defined in the least square sense; these two functions form a practically orthogonal coordinate system in potential temperature‐salinity (θ‐S) space. Thus, in addition to the classical potential temperature‐salinity (θ‐S) diagram, seawater properties can be studied in the potential density‐potential spicity (σ − π) diagram.

    Editorial: Multi-scale fluid physics in oceanic flows: new insights from laboratory experiments and numerical simulations
    (Frontiers Media, 2024-01-03) Cenedese, Claudia ; Huang, Shi-Di ; Jiang, Houshuo ; Yuan, Yeping ; Zhou, Sheng-Qi
    Oceanic flows are characterized by various physical processes that occur over a wide range of spatial-temporal scales, such as eddies, tides, waves, convections, plumes, and turbulent mixing. These flows have great impacts on the oceanic environment (physical, chemical, biological, and ecological) and the global climate, so a comprehensive understanding of their dynamical mechanisms is crucial. However, because of the often-harsh oceanic environment and associated technical difficulties, revealing the multi-scale, multi-physical dynamics of oceanic flows via field measurements remains a considerable challenge. In this context, laboratory experiments and numerical simulations, which can be conducted under precisely-controlled conditions with a relatively low cost, become useful tools for tackling this problem.
