From page 47... ...
appearance of white caps at the crests of exceedingly steep and breaking surface gravity waves, patches of small-scale turbulence left by breaking internal waves, the shedding of mesoscale rings and eddies by large-scale currents (such as the Gulf Stream or the Agulhas current) , and the occurrence of localized anomalies in SST including El Nifio events with a time interval on the order of years.

From page 48... ...
To better characterize the scope of statistical issues that the weak turbulence theory or alternative statistical approaches could address, a brief review of some issues related to w~nd-generated surface gravity waves is in order. Until recently, statistical studies of field geometry were dominated by the work on Gaussian fields.

From page 49... ...
Now, for instance, numerical simulation of electromagnetic scattering by individual realizations of the random sea surface has become feasible. In this regard, simulated non-Gaussian random fields that satisfy basic conservation laws of fluid dynamics represent a great interest.

From page 50... ...
Analysis of random fields that appear as solutions of stochastic partial differential equations (of special interest are equations driven by non-Gaussian noise or noises over a product of time-space and location-space)
