1. Introduction The principal phenomenon studied in this paper is the existence of multiple, alternating zonal jets in the oceans. The observational evidence of these jets emerged mostly over the last few years, and their theoretical understanding is incomplete. In this introduction we pose the problem, discuss the background, and describe the ocean model. The phenomenology of the modeled jets is described in section 2 . Section 3 focuses on the kinematical analysis, section 4 on the

concerned here with the Equatorial Undercurrent (EUC) and South Equatorial Current (SEC), as they account for most of the depth-integrated flow. There is also intense time-mean upwelling, to feed the poleward Ekman flows on either side of the equator. However, meridional flow near the equator is neither well measured observationally, nor well understood theoretically. Our aim is to explore the kinematics of near-equatorial Pacific flow in an eddy-permitting global ocean model. Understanding meridional

1. Introduction Wave-induced near-surface kinematics of nonlinear random waves are important, for example, for understanding remote sensing signals (e.g., Rascle et al. 2014 ) and for interpreting motions of wave-following instruments (e.g., Herbers et al. 2012 ; Herbers and Janssen 2016 ), wave forcing on offshore structures (e.g., Donelan et al. 1992 ; Schløer et al. 2011 ; Deng et al. 2016 ), oil droplet transport (e.g., Geng et al. 2016 ), and wave-driven surface flows and Stokes

interactions that occur between turbulence and surface waves. Surface waves affect turbulence in a kinematical sense as well as a dynamical sense. Turbulent eddies are advected in an unsteady way by wave orbital motion; therefore, assigning a physical interpretation to velocity and scalar fluctuation at a fixed location is complex ( Lumley and Terray 1983 ). Additionally, a conceptual problem arises when an Eulerian framework (fixed reference frame) is used for analyzing turbulence in the presence of waves

(besides whitecaps counting) and relying on human decision regarding the exact moment of the inception of breaking complicates the experimental research. Through the last decades, progress has been made in numerous numerical and experimental studies of the topic, and various geometric, dynamic, and kinematic criteria for waves breaking have been suggested and examined. In recent studies, several reviews of suggested criteria were presented (e.g., Babanin 2011 ; Williams 1981 ; Stansell and

the basin-scale variations of amplitude and phase emphasized by Miller et al. (1993) . With the availability now of over 8 yr of T/P altimeter data, more definitive empirical maps of the LPT are possible. In this paper we present a new empirical map of Mf, confirming that there are significant basin-scale deviations from equilibrium. We then show that this large-scale pattern can be explained with a very simple model of interconnected basins. The model is largely kinematic: self-consistent (i
