I've heard (haven't tried this myself) that you can stop this sort of turbulence if your windbreak is a bit porous - eg if you build a paling fence as a windbreak then leave small gaps between the palings, and also leave a gap under the bottom of the fence between the fence and the ground.
This all helps (apparently) to stop low-pressure regions forming behind the wind break where you and your scope are hiding.
I'll be trying this for myself shortly, I'm building a 2.5m high paling fence around teh concrete pad where I have my pier - I'll let you know if it works, or if it's all ...umm... hot air :-)
