@BeginDescription
Let @file{ifile} be a time series of daily maximum wind speeds WX,
then counted is the number of days where WX > V. The value of V
corresponds to the wind speed at the Beaufort number indicated by
the optional parameter bnum. 
The date information for a time step in @file{ofile} is the date of
the last contributing time step in @file{ifile}.
