Not to single you out, because you raise a good point - but to everyone asking the question about the “wind direction”....just remember that ships move at a slow rate of speed and winds don’t typically remain the same direction for more than 24-48 hrs.
In our nation the wind generally moves West to East, or perhaps North West to South East. I realize there are variations from that, but I had hoped the Japanese wind currents were somewhat true to one norm.
There are of course times when our prevailing winds do a 180, but it’s not all that often that wind from San Diego moves up to L. A. If anything both L. A.’s and San Diego’s winds move eastward.
Of course that isn’t cast in granite either.
As a follow-up to our earlier exchange on prevailing wind direction around the nuclear plant in Japan, I noted that while it was reported the other day that the wind was coming from the South there, yesterday it was coming from the North.
That can’t be too helpful. It’s going to spread radiation in more than one direction.
