There is another interesting fact. Sometimes, the SFO report in Ken
Pulton's mailer is higher than what you get from the SFO phone line.
On several occasions, I saw, say, 18 knts at 3:10 in Ken's report, called
the airport at 3:15 and got, say, 13. The airport phone info is a
recording, and I was under impression the same data goes into ken's
report.
No?
As callwind is concerned, it's more clear. The guys calibrate their
readers. I.e., what they show us is not what they get from sensors.
They make corrections trying to project what is on the water from
what they measure on shore. Trouble is, their correction function
is apparently does not take into consideration the wind direction.
It is done for the prevailing wind. Accordingly, when the wind blows
west instead of usual sw at Crissy pager shows 19 w gusts to 25
while it's so calm one could play badminton. As soon as direction changes
to more common sw or ssw the report drops to 9, which is what is on
the water.
I believe the callwind guys who carge for their service should consider
investing part of the proceeds into installing sensors on buoys, bridge
pillars, barges at 3rd, Anita rock, etc. Who needs wires in the midst of
Silicon Valley these days?
At least, they should stop making unannounced changes to their
calibration functions. We all develop our own calibration coefficients.
When call of the wind changes theirs whithout telling us about it the
trouble starts. One sees 22 w gusts to 28 at Coyote, leaves workplace to
head there and finds no wind. With hourly consulting rates of $100 and up,
callwinders, will you compensate for half-day worth of lost revenue?
There is no shortage of lawyers in the area... Class action suit,
anyone? :-)
