I am trying to plot a cross section of Vertical velocity and horizontal (U) winds. This plot is 90 degrees so I am ignoring V winds. Obviously U winds are much stronger than W so I have manually adjusted these by multiplying it by 100. I have included the script below in addition to the screen output. Please can you advise me on how to do this.</font><font face="Arial,Helvetica,sans-serif"><br></font></span></font></div><div style="font-family: Arial, Helvetica, sans-serif; margin-top: 0px;
