@BeginDescription
Let @file{ifile} be a time series of the daily maximum horizontal wind speed
VX, then the number of days where VX is greater than or equal to 32.5 m/s
is counted. A further output variable is the maximum number of consecutive
days with maximum wind speed greater than or equal to 32.5 m/s. Note that
VX is defined as the square root of the sum of squares of the zonal and
meridional wind speeds and have to be given in units of m/s.
The date information of a timestep in @file{ofile} is the date of
the last contributing timestep in @file{ifile}.
