Around the strong currents, like North Equator Current (NEC) and the Kuroshio Extension (KE), meridional variation of the eddy zonal moving speed was much closer to that of the phase speed of Rossby Wave including effects of the zonal mean current.

• 在北赤道流和黑潮延续体等强流附近,涡旋的实际纬向移速与纬向平均流影响下的罗斯贝波相速更为接近。
