Re: Question on wind speed
Since the WS-23XX stations do not support a wind gust reading, the
highest wind speed seen over the past 10 minutes is used.
On the WS-36XX, there is a seperate gust value reported, that value
is used over the wind speed variable to determine gust. The highest
gust value over the past 10 mins is reported to the weather servers
in this case.
The average wind speed and direction calculations are based on the
normal wind speed variable (for both WS-23XX and WS-36XX). Vectors
are used to calculate the average wind speed and direction. CWOP
defines the average wind speeds to include all readings over the past
When you use rapid fire, the current wind speed read from the unit is
reported, the 10 minute gust as defined above is reported as well.
The exception to this is when you check the WU tweak that reports the
average wind speed and direction, minimum. In this case, the average
wind speed and direction are reported if the current wind speed is
equal to or less than the average. If the current exceeds the
average, the current value is uploaded. This allows for the average
to be sent most of the time however if a gust is seen, that is
Even though you are sending data using rapidfire, WU is storing only
pieces of your rapid fire data, probably using an internal timer.
When the timer expires, the next reading is stored. This is just a
