A total of 10 different gradients for 11 height intervals (10 intervals if ws_vertical_gradient_level(1) = 0.0) can be assigned.\\\\

    401401That 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).\\\\
    402402With an appropriate construction of '''w_subs''' the height of the boundary layer ''z_i'' can be kept approximately constant.\\\\
