$i.e.$from steric effects.1826 The second term arises from temporal changes in the global mean density; \ie from steric effects. 1827 1827 1828 1828 In a Boussinesq fluid, $\rho$ is replaced by $\rho_o$ in all the equation except when $\rho$ appears multiplied by 1829 the gravity ( $i.e.$in the hydrostatic balance of the primitive Equations).1829 the gravity (\ie in the hydrostatic balance of the primitive Equations). 1830 1830 In particular, the mass conservation equation, \autoref{eq:Co_nBq}, degenerates into the incompressibility equation: 1831 1831 … … 1874 1874 The above formulation of the steric height of a Boussinesq ocean requires four remarks. 1875 1875 First, one can be tempted to define $\rho_o$ as the initial value of $\mathcal{M}/\mathcal{V}$, 1876 $i.e.$set $\mathcal{D}_{t=0}=0$, so that the initial steric height is zero.1876 \ie set $\mathcal{D}_{t=0}=0$, so that the initial steric height is zero. 1877 1877 We do not recommend that. 1878 1878 Indeed, in this case $\rho_o$ depends on the initial state of the ocean. … … 1890 1890 1891 1891 Third, the discretisation of \autoref{eq:steric_Bq} depends on the type of free surface which is considered. 1892 In the non linear free surface case, $i.e.$\key{vvl} defined, it is given by1892 In the non linear free surface case, \ie \key{vvl} defined, it is given by 1893 1893 1894 1894 \[ … … 1913 1913 so that there are no associated ocean currents. 1914 1914 Hence, the dynamically relevant sea level is the effective sea level, 1915 $i.e.$the sea level as if sea ice (and snow) were converted to liquid seawater \citep{Campin_al_OM08}.1915 \ie the sea level as if sea ice (and snow) were converted to liquid seawater \citep{Campin_al_OM08}. 1916 1916 However, in the current version of \NEMO the sea-ice is levitating above the ocean without mass exchanges between 1917 1917 ice and ocean. … … 1949 1949 - the turbocline depth (based on a turbulent mixing coefficient criterion) (\mdl{diahth}) 1950 1950 1951 - the depth of the 20\deg Cisotherm (\mdl{diahth})1951 - the depth of the 20\deg{C} isotherm (\mdl{diahth}) 1952 1952 1953 1953 - the depth of the thermocline (maximum of the vertical temperature gradient) (\mdl{diahth}) … … 1968 1968 (see the \textit{\ngn{namptr} } namelist below). 1969 1969 When \np{ln\_subbas}\forcode{ = .true.}, transports and stream function are computed for the Atlantic, Indian, 1970 Pacific and Indo-Pacific Oceans (defined north of 30\deg S) as well as for the World Ocean.1970 Pacific and Indo-Pacific Oceans (defined north of 30\deg{S}) as well as for the World Ocean. 1971 1971 The sub-basin decomposition requires an input file (\ifile{subbasins}) which contains three 2D mask arrays, 1972 1972 the Indo-Pacific mask been deduced from the sum of the Indian and Pacific mask (\autoref{fig:mask_subasins}). … … 2060 2060 \biblio 2061 2061 2062 \pindex 2063 2062 2064 \end{document}
