      Subtropical western boundary currents are warm, fast flowing currents that form on the western side of ocean basins. They carry warm tropical water to the mid-latitudes and vent large amounts of heat and moisture to the ...
    • Enhancement in vertical fluxes at a front by mesoscale-submesoscale coupling 

      Ramachandran, Sanjiv; Tandon, Amit; Mahadevan, Amala (John Wiley & Sons, 2014-12-12)
      Oceanic frontal instabilities are of importance for the vertical exchange of properties in the ocean. Submesoscale, O(1) Rossby number, dynamics are particularly relevant for inducing the vertical (and lateral) flux of ...
