The case presented is very extreme and only serves for the purpose of
showing the importance of wind factor.

How ever, on normal hives, in my experience, there is also a big difference
between those hives that are protected, shielded for the cold and dry
winter wind and those that are not.

As drier and permanent is the, for our case, southearly wind, the more that
the colony suffers.

That wind drains vital energy from the colonies. The cluster evaporates and
thus feels the dewpoint temperature that is much lower than ambient
temperature and proportional to the relative humidity of such air.
