When ocean currents approach a coast, their direction may be influenced by wind shear stress and the coastline, leading to complex patterns of water movement.
When an ocean current approaches the coast of a large landmass, the direction of the current may change due to various factors such as wind shear stress and the influence of the coastline. In general, the upper water layers tend to move in the direction of the wind, creating seaward- or landward-directed currents. However, the coastline acts as a barrier, causing an opposite-directed water mass transport in the lower layers to compensate for the upper layers' movement.
