    3415          Sets the time period a precursor run shall run uncoupled. This parameter is used to set up the precursor run control for atmosphere-ocean-coupled runs. It has to be set individually to the atmospheric / oceanic precursor run. The time in the data output will show negative values during the precursor run. See documentation  for further information.

    17305       The large scale vertical motion is only applied to the prognostic equation for the potential
    17306       temperature because it cannot be applied to the momentum equations due to incompressibility.
     17296      The large scale vertical motion is only applied to the prognostic equation for the scalar quantities (potential
     17297      temperature, humidity if  <a href="chapter_4.1.html#humidity">humidity</a> = .T. or passive scalar if <a href="chapter_4.1.html#passive_scalar">passive_scalar</a> = .T.) because it cannot be applied to the momentum equations due to incompressibility.
    1730717298      Thus, the model is not mass consistent.</p>
