@BeginOperator_rotuvb
@Title     = Backward rotation
@Parameter = u v ...

@BeginDescription
This is a special operator for datsets with wind components on a rotated grid, 
e.g. data from the regional model REMO. It performs a backward transformation of 
velocity components U and V from a rotated spherical system to a geographical system.
@EndDescription
@EndOperator


@BeginParameter
@Item = u,v,...
STRING  Pairs of zonal and meridional velocity components (use variable names or code numbers)
@EndParameter


@BeginExample
To transform the u and v velocity of a dataset from a rotated
spherical system to a geographical system use:
@BeginVerbatim
   cdo rotuvb,u,v ifile ofile
@EndVerbatim
