vortex, the stratification is strong, and it is only the density that is important, not the temperature–salinity distribution. In future work we will study lens vortices in a primitive equation model, which will allow us to determine the merit in making some of these assumptions. This will allow for a more accurate description of the unstable modes in the very small Burger number regime. In this manuscript we sought to understand how lens vortices, idealized with a Gaussian streamfunction

impact of the model resolution will only be estimated in terms of AMOC z since the absence of monthly temperature and salinity (hence density) files prevented us from computing in certain simulations. All other analyses, however, will take advantage of estimates. In accordance with Zhang (2010) , our ¼° captures the diapycnal water mass transformation (DWT). At high latitudes in particular (i.e., a region where steep isopycnals are common) there therefore can be substantial differences

; Conkright et al. 2002 ), and surface temperature is relaxed to the climatological mean with a time scale of 1 month. Salinity is uniform at 35 throughout each simulation, a simplification that is acceptable for our purpose. The integrations span 50 yr for solution 1, 30 yr for solution 2, 9 yr for solution 1.5, and 15 yr for solution 1.8. The 5-day averages are archived in all years for solution 1 and in years 24–29 for solution 2. (The 5-day averages and snapshots are nearly identical.) The 1-yr means
