[1][clarification needed] It is also characterized by an unforeseen change in wind direction, and speed across its surface between water systems, which are based on temperature and salinity.
It is made up of fronts of multiple weak sea surface temperature (SST), aligned northwest–southeast, spread over a large latitudinal span.
[2] A dynamical frontal zone sits at the southern limit of the saline subtropical waters on the western sides of basins.
The areas of most positive wind stress curl are characterized by very weak sea surface temperature incline, and are likely consistent to regions of mode water.
Due to the constant thermohaline circulation fronts, cold air flows near the surface and bottom of the ocean.
