For reasons I don't want to go into, I knew this paper would be appearing in the very near future and it finally got published online in the EGU journal Atmospheric Chemistry and Physics Discussion.
ACPD is the online open review process for the print journal Atmospheric Chemistry and Physics, so by tracking the link you can see how scientists respond to the idea. Many lay people read this as a news blurb in various outlets and are treating it as a joke. However, it is not. The authors are fairly well respected modelers and if you do the calculations, large wind-power grids extract a small, but significant amount of power from the wind field (I vaguely recall the number is something on order of 5%, but I might be off by a factor of 2 low and 3 high). So it is plausible, or at least plausible enough that the paper will get a decent peer-review, that wind power arrays will result in weather modification.
There is no such thing as a free lunch. *Any* method to generate the amount of energy a highly technological society of many hundreds of millions of beings requires on a daily basis will have ecological/environmental consequences.
