"At the recent meeting of the American Association for the Advancement of Science, Mark Z. Jacobson, a professor of Civil and Environmental Engineering at Stanford, spoke in a session on renewable energy.
Jacobson was invited to speak at the conference because he has developed a roadmap to convert the entire U.S. to renewable energy using primarily wind, water, and solar generated energy. His detailed analysis includes looking at costs and benefits on a per-state basis, including the obvious benefits to human health from reduced pollution. One of his slides showed a very unexpected benefit, however: taming of destructive hurricanes with the help of offshore wind farms.
Jakobson's study, co-authored by Cristina L. Archer and Willett Kempton, has been published in Nature Climate Change (full text available here)."

I dare say that height is not irrelevant. What effect are wind turbines of a few hundred feet going to have on a storm with a height of 10 miles? (The turbine is about about 3/4 of a percent of the height of the storm) The spoon example doesn't really compare, the spoon is about 30% the height of the "storm", impedes about 50% of the flow at its level, and the flows have pretty much no similarity (Reynolds number.)
Now they propose putting the turbines out in the Atlantic "where the storms form"?... Most hurricanes that hit the United States begin either in the Caribbean or the Atlantic. Many of the worst start as seedlings coming off the coast of Africa.
That's a rather large area and at a significant distance.
Finally, "...bring the whole thing to a halt..." Will result in a large force being applied to the structure and the blades. Even if they are feathered (turning them so they will show minimal resistance to the flow).
