Hi all,

I'm in the process of building an anemometer and I'm trying to work out what
kind of results I would like from it.

I'm obviously going to want average wind speed and gust wind speeds but I'm
not sure what kind of time range averages should be taken over and what the
official definition of a gust wind speed is.

I've seen official sites talking about 10 minute averages and 1 minute
averages. Is there a specific time duration of set of durations that I
should be averaging over?

Is a gust speed measured over any time interval at all or is it just
determined by how quickly the anemometer cups can respond to a sudden
increase in wind speed. If this is the case doesn't that make a wind gust
rather subjective as your measurement will depend on your model of
anemometer?

Any help appreciated, or feel free to point me at a relevant web site if
there is one.

Cheers
David
