leeward

Due to their leeward location, the islands receive only 350-550 mm of rain per year.

The most important rule of sail trim is to avoid turbulence on either side, __especially__ the leeward side.

Either way, the leeward side would definitely be a higher risk area.

Or at least a conspicuous vane on the leeward/downwind side that makes the whole thing a little more conspicuous to birds.

In fact, I think the windward side of all the Great Lakes are similar and might be in different climate zones vs the leeward side of the lakes.

Albatrosses have for years been known to use the flight pattern of leeward dives, windward climbs to move around, which is what this paper describes.

' That is, air is still pushing on the leeward side of the sail, but with less pressure than on the windward side, and that this reduction in pressure is greater when the flow is attached, as you imply.

The total energy finally reaches its maximum value during the leeward descent, after the bird has already started to loose altitude.

To be theoretical, attached flow on the leeward side is going to exert less pressure than detached flow would, due to irreversibilities in the detached turbulent flow.

The trouble only really comes in when we try to use these pragmatic models as scientific models!> Assuming the flow is attached on the leeward side, does that side also turn flow and generate force?Notionally, yes.

If you look at the wind resource potential around 100m, there are places where it might be feasible to place turbines in areas you don't normally think of as windy, most likely a ridge on the predominately leeward end of a plain.
