Ab:
I would like to "tag on and expand" on the assessment that "Wxgeek"
provided on 11/15 concerning the 100 mph wind gusts issue at the Beaumont 133
RAWS at or about the time of the tragic BDF-Engine 57 burnover on October 133
26, 2006. "Wxgeek" suggested that there might be another explanation for 133
the "100 mph gusts" that showed in the data stream from the Beaumont RAWS. 133
That hypothesis is right on!
A review of the hourly observations for the Beaumont RAWS stored 133
at the Western Region Climate Center in Reno, NV 133
(
www.wrcc.dri.edu/cgi-bin/rawMAIN.pl?caCBEU ) shows that parity 133
errors during the transmission of the data resulted in the "gust direction" 133
of 100 degrees being pushed to the right, and into the "gust speed" column. 133
Persistence of the gust speeds before for and after the transmission 133
anomalies supports this. The "100 mph anomaly" occurred 5 times in the 133
data set for October 25-27, 2006.
The patterns present in the data suggests that there were not gusts of 100 133
mph, and that the gusts were more probably in the 30 - 40 mph range. The 133
final determination will, of course, rest with those associated with the 133
investigation teams.
Thanks.
