For some time now I've noticed when I look at the graphs that the peak gust, wind gust and wind speed records are nearly always identical. I've now worked out that the only time they are being recorded properly in the monthly data file are the times when Cumulus is running on my computer (on average about three hours per day). At all other times the figures are identical, and on looking back I find that this started on 11 February 2010.
It's not too important to me, but I'd be interested to know if anyone has ideas as to what has gone wrong, and how I might be able to fix it. I can't remember doing anything particular to Cumulus last February - but then I can't remember much of what happened yesterday.
