If u(time,lev,lat,lon) and lat spans -90 to 90

then
 
     printVarSummary(u) ; u before
     
     u = u(:,:,::-1,:) ; data and coordinate variable
                         ; will span 90 to -90
                         
     printVarSummary(u) ; u after
     
look at the coordinates before and after
                         
The units "degrees_north" is a standard convention.
You do not want units of degrees_south.
