My theory about that is: The slight trend of partial-global heating ... due almost entirely to the Sun's slightly increased activity of the late 90s to mid 00s warmed up the oceans a bit. Now that the sun has gone into a cool cycle, the differential between the still somewhat warmer oceans, and the much cooler (now) atmosphere due to decreased solar activity is causing the wind.
Or more simply: When warm and cold meet, be they ocean currents, air currents or a combination thereof, turbulence results.
Like I said, I don’t know why, but anyone who lives on the coast knows that the wind picks up at daylight then used to ease off and pick up around dark. Also when the tide changes, so your theory makes sense, just on a bigger scale.
