Guess what is causing this rather erratic windspeed graph?

windy showers?

No, not even close. It has something to do with and a wind gust just over 24 hours ago.

Your anemometer is no longer at an appropriate angle?

You are the winner

Actually, I was doing some maintenance and had my 5m pole down. Went inside to get some batteries (lithium) to change them while I was at it. My daughter looked out the window and announced, "Dad, your ladder fell over!"

Result, shattered one cup and broke the point off the wind vane.

So, that is what 2 out of 3 cups does to the wind speed graphs. Wind vane still works and if anything, doesn't flit around so much.

Spare parts are on the way.

I'm glad it wasn't because you were on the ladder, and the cup was the only thing to grab onto as you went down...

I've broken one of the arms/cups off my test anemometer Probably glue it up with Araldyte.

Oh, this one was shattered beyond recognition. Counted the bits - total 6 bits, and I don't know if I have them all.

Short of buying a new anemometer unit, perhaps one of your wife's measuring spoons or cups is the right size . Might need balancing after glueing onto the stub though.

Ping pong balls cut in half make good anemometer cups. (pardon me - table tennis balls). They are the same size as the FO cups. In fact I intend to make my own anemometer later as part of a complete weather station.

Have ordered an anemometer and a windvane unit for the fine offset from an Australian eBay supplier.

While I was at it I ordered a WH2081 (AU$92) including postage from the same supplier. This unit will be for the school I work at approx 65km (direct) from my home. It will be an interesting project working with students (and another teacher) to set it up and get the website up and running. Quite exciting really.

What an excellent idea...

There is one already in SA at Hallet Cove School. I have a link to it on my site under "Other PWS Websites". Here's the direct link http://www2.hcs.sa.edu.au/Curriculum/Weather.aspx

Ours will be set up so in the library with a dedicated display (running in kiosk mode). The library is also a Public Library so hopefully there will be quite a bit of interest in the project from the community as well.
