| Well it's not so much the idea of local winds but winds summed in the Atlantic in general the produce the Gulf Stream. It's a giant gyre, first described as such by Ben Franklen. It's actually been proven to be a gyre by a African prince who research on the side by putting bottles with notes in them to send the notes back to him where they were discovered. And they were discovered in places down gyre, so to speak. It's not as obvious that there is a gyre on the African/Euro side to the gyre where it really slows down. Of course along the east Florida coast a man on a raft could drift 100 miles in a day in the gulf stream. The winds are the trade winds that blow to produce the gyre. The gyre also would be affected by such things as sinking dense evaporated oceans to the north, and otherwise ocean currents but for the most part the winds would drive such significant variable change. Significant variable change wouldn't be explained, BTW, by cities being built, B-lowcountry, because the cities would then not explain how the tides go down variably. City and river changes may explain some more permanent changes to the coasts, of course, but that isn't what was measured here. |
