+This parameter assigns the value of the u-component of the geostrophic wind ('''ug''') at the surface (k=0). Starting from this value, the initial vertical profile of the u-component of the geostrophic wind is constructed with [#ug_vertical_gradient ug_vertical_gradient] and [#ug_vertical_gradient_level ug_vertical_gradient_level]. The profile constructed in that way is used for creating the initial vertical velocity profile of the 3d-model. Either it is applied, as it has been specified by the user ([#initializing_actions initializing_actions] = '' 'set_constant_profiles' '') or it is used for calculating a stationary boundary layer wind profile ([#initializing_actions initializing_actions] = '' 'set_1d-model_profiles' ''). If '''ug''' is constant with height (i.e. '''ug'''(k) = '''ug_surface''') and  has a large value, it is recommended to use a Galilei-transformation of the coordinate system, if possible (see [#galilei_transformation galilei_transformation]), in order to obtain larger time steps.\\\\
+'''Attention:'''\\
+In case of ocean runs (see [#ocean ocean]), this parameter gives the geostrophic velocity value (i.e. the pressure gradient) at the sea surface, which is at k=[#nzt nzt]. The profile is then constructed from the surface down to the bottom of the model.
