摘要

采用水平分辨率为250 m的高分辨率模式，分析了波罗的海海面涡旋场和动能分布。结果表明，风速与海面动能和海面垂直平均动能关系密切，而海面动能与涡旋场关系滞后。动能的空间格局表明波罗的海西部和南部有更强的能量流。涡度分布不均匀，各海区涡度分布差异显著。亚中尺度特征分布也不均匀，在格但斯克盆地、芬兰湾和波罗的海北部西部更频繁地出现。

Submesoscale processes in the surface layer of the central Baltic Sea: A high-resolution modelling study

A high-resolution model with a horizontal resolution of 250 m was used to analyze the surface eddy fields and the distribution of kinetic energy in the Baltic Sea. The results indicate a close relationship between the wind speed and the kinetic energy at the surface and the vertically averaged kinetic energy in the sea, and a lagged correlation between the kinetic energy at the surface and the eddy field. The spatial patterns of kinetic energy indicate more energetic currents in the western and southern parts of the Baltic Sea. The distribution of vorticity is inhomogeneous and differs significantly between sea areas. Submesoscale features are also inhomogeneously distributed and occur more frequently in the Gdańsk Basin, the Gulf of Finland, and the western part of the northern Baltic proper.
