+Gradient(s) of the profile for the large scale subsidence/ascent velocity (in (m/s) / 100 m). 
+
+This gradient holds starting from the height  level defined by ws_vertical_gradient_level (precisely: for all uv levels k where zu(k) > ws_vertical_gradient_level, w_subs(k) is set: w_subs(k) = w_subs(k-1) + dzu(k) * ws_vertical_gradient) up to the top boundary or up to the next height level defined by ws_vertical_gradient_level. A total of 10 different gradients for 11 height intervals (10 intervals if ws_vertical_gradient_level(1) = 0.0) can be assigned.  
+
+Example: 
+
+      ws_vertical_gradient = -0.002, 0.0, 
+      ws_vertical_gradient_level = 0.0, 1000.0,
+
+That defines the subsidence/ascent profile to be linear up to z = 1000.0 m with a surface value of 0 m/s. For z > 1000.0 m up to the top boundary the gradient is 0.0 (m/s) / 100 m (it is assumed that the assigned height levels correspond with uv levels).
+
+With an appropriate construction of w_subs the height of the boundary layer z_i can be kept approximately constant.
+
+Attention:
+The large scale vertical motion is only applied to the prognostic equation for the scalar quantities (potential temperature, humidity if humidity = .T. or passive scalar if passive_scalar = .T.) because it cannot be applied to the momentum equations due to incompressibility. Thus, the model is not mass consistent.

+Height level from which on the gradient for the subsidence/ascent velocity defined by ws_vertical_gradient is effective (in m). 
+
+The height levels have to be assigned in ascending order. The default values result in a profile which is zero everywhere regardless of the values of ws_vertical_gradient. For the piecewise construction of the subsidence/ascent velocity profile see ws_vertical_gradient.
