The straight kind accounts for 1/3 and the meander kind accounts for 2/3. 2) The warm eddies on the northern side originate mostly from the area off Sanriku and Joban of Japan. Their moving paths lie in two patterns: Pattern I, eddy moves northeastward or northward ; Pattern II. eddy rotates about the original area.The cold eddies on the southern side originate mainly from the area off Boso Peninsula.
