[gradsusr] Cumulative Output

[Jeff Duda]

Daniel,
This is a WRF issue, not a grads issue. If you want to see swaths, you need
to integrate the model field over individual time steps, something you'd
have to alter the WRF code to do. If you just want maximum updraft helicity
between history intervals, however, the AFWA diagnostics package can help
you with that. It's set in the namelist.
