How do they report wind speed?
 

How do they report wind speed for a past day in MPH, since the wind is
constantly getting faster or slower? Do they average it, or maybe
just give the maximum speed?

It's a 10 minute average, according to the WMO rules

Who reports just one figure for a whole day?
Usually you hear something like "20 to 30 mph in the afternoon,
with gusts up to 50"

They report it by publishing it in a newspaper, or by reading it
aloud
over the radio, or on a television set. It can also be reported on
the Internet.

Check out www.wunderground.com and plug in your location (works for
USA at least). Scroll down and find link for historical data. Then
scroll down to look at charts.

They station gnomes all over a region that is expected to have high
winds. They do a rough measurement of how fast the wind is going by
how much the tops of their caps get blown over in the wind. Every time
this happens, the gnomes write their guesses down on paper, and send
it via carrier pigeon to the NWS office. A man there tabulates and
comes up with an estimate based on the figures the gnomes have written
down.

Also, when you see a red radar spot on the map indicating severe
weather in the area, it's not a computer rendering, but an actual
photograph of a swarm of gnomes blowing about in the wind after a
tornado smashed through their village.

It's recorded as a 24-hour mean of speed and direction with the mean of
the speed of all gusts as well as the maximum gust both noted
separately. Hourly and monthly averages are also recorded. This is used
for climatology records. However, a "normal" report like you get from
the TV for current conditions is the instantaneous direction and speed at
the time the observation is taken. It is not an average.
