Long range Kelvin wave propagation of transport variations in Pacific Ocean equatorial currents

Two 100 km scale arrays of moored upper ocean current meters, one near 0, 152W, the other near 0, 110W, were used to study the zonal transport of the strong equatorial currents in and above the thermocline. At long periods (several days), fluctuations· in the vertically integrated zonal velocity (transport per unit meridional distance) at a single equatorial mooring were highly correlated with fluctuations in the total transport across the section 0-250 m and 1N-1S, which includes most of the Equatorial Undercurrent...
