Under this area of enhanced surface exchange, the ocean responds by altering its stratification and forming a water mass with deep winter mixed layers of up to 500m thickness. In the North Atlantic Ocean, this subtropical mode water is called Eighteen Degree Water (EDW). Data indicate that frontal processes are important in EDW formation: much like atmospheric convection can be affected by atmospheric frontal dynamics that does not exist in a simple 1-D atmospheric boundary layer response to heating from below.
