Wind speed profiles. Ah one of the one topics I couldn't do either.

Yes, can understand that.

'The wind speed profile equation is u(z)=uo(z/zo)^p, where u(z) is the windspeed at height z, and uo is the windspeed at a reference height zo. Hence 1n[u(z)]=ln[uo]+p*ln[z/zo]. Take uo to be the windspeed measured at the to anemometer, plot ln[u(z)] against ln[z/zo] and hence determin p.'



Would be fine if I could work out the difference between all the symbols, but no...

Did you make notes during the lectures on the formulae? If you did, use them.

That was all the notes I've ever had. Reading though is making me more confused.
u(z) is the windspeed at height z, so that's alright, but zo I'm stuck on.
I can't work out what is meant by 'reference height'
Hmmm, it means the top anemometer?
I'll try drawing the graph and seing if it looks plausable.

Well, you'll be no better off if you don't.
