Don,
I had the same result when looking at my former location in the Colorado
high country, at 9,200 feet: "Special Wind Region"
Google "Special Wind Region"
"There are special regions in which wind-speed anomalies are known to
exist…Winds blowing over mountain ranges or through gorges or river
valleys in these special regions can develop speeds that are
substantially higher than the values indicated on the map. When
selecting basic wind speeds in these special regions, use of regional
climatic data and consultation with a wind engineer or meteorologist is
advised.
It is also possible that anomalies in wind speeds exist on a
micrometeorological scale…Wind speeds over complex terrain may be better
determined by wind-tunnel studies."
Cheers,
Gene K5GS

Tnx for sharing that Gene. No numbers came up for this location, but
I've maintained a WX station and auto- recorded daily most aspects of
the local wx since 2007. At my exposed location we experience
interesting wind conditions during the year!!!!!! I've a pretty good
grasp on what to expect here. So far, everything has stayed up during
even the most severe wind condx.
If ever thinking of visiting the scenic Oregon coast, there is a site
owned by the OCRG (Oregon Coast Repeater Group) providing current wx
conditions 24/7 from Rockaway Beach to Yachats on the OR coast at
http://www.ocrg.org/telemetry_feed/ocrgwx.html. All of this
information is fed to the NWS through MesoWest.
Most of the wx stations are located at ham locations. I'm the
'Yachats' site. We also host AIS and ADS-B receiving and reporting
stations.
Other interesting information is also available on the OCRG site.
I know a lot of hams have wx instruments mounted outside (some on
towers, some on roofs, etc) but few installations are designed around
the NOAA/NWS wx instrument siting standard. The siting standards for
the various wx reporting instruments such as, temp, humidity, rain,
wind, etc are difficult to meet for most ham installations, so most do
what works.

Subject: [TowerTalk] Wind Speed by Location
Didn't see this in the archives, maybe of interest to the TowerTalkians.
I was poking around the Internet last night and bumped into the website
of the "Applied Technology Council": *
http://windspeed.atcouncil.org/
*Enter your address and the site returns the wind speeds for that
location.
