I guess I would look at it based on design precepts for a wind break I've seen
online and what raw materials I had nearby or inexpensively obtained, so a few ideas.
Find an old crapped out commercial box trailer that could be utilized as a portable windbreak. Advantages would include being able to extend the length and height by attaching materials to the side. Also I it would presumable retain some of its value once it use as a windbreak either as storage or by selling. Disadvantage would be difficulty of repositioning requiring a truck, issues relating to oil compaction or just not being able to get a truck over the field, even if available at a reasonable cost. Use an old truck to park as a windbreak, similar issues as above plus added effort maintaining the vehicle so it could be moved.
A CONEX container would make a decent solid windbreak. If placed on round
wood logs movement with a pickup truck or tractor is feasible depending on the terrain.
Get a flatbed trailer and construct a frame our of metal or wood on it and faced with available materials to make your windbreak. Advantage is moving could be done rather easily. Weight and/or outriggers would probably be needed to keep it from being blown over. What you see in image searches online that either rough boards or steel highway guardrails attached to metal frames (sometimes with wheels).
Based on whatever is utilized, estimates of the area affected by the windbreak, creating shelter from the harsh winds
should be able to be estimated with some accuracy. My reading on windbreaks is that natural stands of trees and hedges used as windbreaks allow for some air to pass through creating a buffer area of slower wind on both the windward and leeward sides of the break, say for argument 10 MPH vs 30 MPH. A solid fence, such as a stone wall, while creating g a buffer on the windward side has a tendency to create turbulence on the leeward side. So it follows that gaps in the windbreak allowing some wind at a reduce velocity to exfiltrate through may not be a bad thing.
Good luck with your
project!
