By default, version 4.6 of RegCM includes the flexible mixed layer modeling system of the SOM developed by the Laboratory of Geophysical Fluid Dynamics (LDFG; Giorgi et al., 2012). In our study, SOM is a simple thermodynamic oceanic layer having a constant thickness of 50 m. The ocean surface warms or cools in response to surface heat exchanges with the atmosphere. SOM interacts with the atmosphere to calculate SST and ice parameters by forcing the model with RegCM fluxes. The fluxes that drive each iteration are provided to the SOM for the SST update, which is then transmitted to RegCM for the next iteration. But the lack of ocean dynamics (convection, advection, and fusion motions) can lead the model to make poor simulations. To solve the problem, a set of heat flow adjustments is specified by adding a term commonly referred to as “q‐flux.” The q‐flux is being added to the SOM at each time step to provide a realistic SST distribution by the model. The technical documentation of the SOM can be consulted on the following website: http://www.gfdl.noaa.gov/fms‐slab‐ocean‐model‐technical‐documentation.
