WebVertical mixing occurs because the hurricane’s surface winds exert a stress on the ocean surface due to friction, generating ocean currents in the oceanic mixed layer. Vertical shear of the currents in the upper ocean then leads to turbulence. Turbulence mixes and entrains the colder water from the thermocline up into the oceanic mixed layer ...

WebLayers where properties are changing rapidly with depth are called “clines”, so where temperature changes quickly is the thermocline, where salinity changes fast is the halocline, and where density changes rapidly is the pycnocline. Oftentimes, there are regions where there is no change with depth, and these are called mixed layers. WebTropical cyclones (TCs) typically produce intense oceanic upwelling underneath the storm’s center and weaker and broader downwelling outside upwelled regions. However, several cases of predominantly downwelling responses over warm, anticyclonic
