A series of recent mo deling studies suggest the vertical structure \nis fairly well-captured by a single mode\, intensified near the surface and\ndecaying to zero with d epth. A study of 69 globally-distributed current \nmeters supports this\, in many locations outside of the tropics. The reason\nfor the dominance of a surface is explored theoretically\, using a simple\ntwo layer model. Th e latter predicts a wavenumber frequency spectra \nwhich resembles that in the ocean\, except at small scales. The latter are \nshown to be more lik ely to transfer energy to large scales\, leaving the\n(non-dispersive) lar ge scale waves in tact. A similar conclusion was made \npreviously from id ealized numerical experiments.
