Without getting into an extensively technical treatise on wood and moisture content (remember the cucumbers? It's more complicated than that) Freshly cut wood has a lot of water, some of it is bound up int the cells and some is "free" i.e. between the cells.

The Moisture content of the wood is significantly greater than that of the air and the moisture of the wood eventually reaches equilibrium with the air (or very close)

Once the bound water leaves the cell, it doesn't really enter the cell again, it mostly will saturate the wood fibers between the cells. It doesn't take a whole lot of air circulation to dry out wood. Wood loses most if its moisture through the end grain, not through the side grain. Stacking the wood on its side with the ends exposed to air will bring the wood to equilibrium MC pretty quickly. Especially in winter.
