     17276       by <a href="#ws_vertical_gradient_level">ws_vertical_gradient_level</a>.
     17277       A total of 10 different gradients for 11 height intervals (10 intervals
     17278       if <a href="#ws_vertical_gradient_level">ws_vertical_gradient_level</a>(1)

     17295         to z = 1000.0 m with a surface value of 0 m/s.
     17296         For z &gt; 1000.0 m up to the top boundary the gradient is <i>0.0</i> (m/s) / 100 m
     17297         (it is assumed that the assigned height levels correspond
     17298         with uv levels).</p>
     17299           
     17300       <p>With an appropriate construction of w_subs the height of the boundary layer z_i
     17301        can be kept approximately constant.</p>
     17302     
     17303   <p><span style="font-weight: bold;">Attention:</span><br>
     17304
     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.
     17307      Thus, the model is not mass consistent.</p>
