v3 v4 1 [[NoteBox(warn,This site is currently under construction!)]]2 3 1 = Ocean option = 4 2 PALM allows for studying the ocean mixed layer (OML) by using an ocean option where the sea surface is defined at the top of the model, so that negative values of ''z'' indicate the depth. Hereafter, we keep the terminology and use the word ''surface'' and index ''0'' for variables at the sea surface and top of the ocean model. For a list of ocean specific parameters, see the following Table 3. … … 51 49 [#jackett2006 Jackett et al. (2006)]. The algorithm is based on polynomials depending on Sa, ''θ'', and ''p'' (see [#jackett2006 Jackett et al., 2006], Table A2). At the moment, only the initial values of ''p'' enter this equation.\\ 52 50 The ocean is driven by prescribed fluxes of momentum, heat and salinity at the top. The boundary conditions at the bottom of the model can be chosen as for atmospheric runs, including the possibility to use topography at the sea bottom.\\ 53 Note that the current version of the ocean option does not account for the effect of surface waves (e.g., Langmuir circulation and wave-breaking). Parametrization schemes might, however, be provided within the user interface (see Sect. [wiki:doc/tec/user user interface]) and have been used, e.g., by \citet{noh2004}. The ocean option in its current state was recently used for simulations of the ocean mixed layer by \citet{esau2014}, who investigated indirect air-sea interactions by means of the atmosphere-ocean coupling scheme that will be described in Sect. [wiki:doc/tec/coupled coupled atmosphere-ocean simulations].
