Applications for Advanced Studies

WithVictor Raizer

This chapter discusses the possibilities to observe a number of the so-called weakly emergency events. Research-based assessment is considered with the goal to determine the signature performance. In most environmental situations, ocean turbulent wake represents a stochastic compact system of small-scale (horseshoe) vortexes with highly spatial variability. Parametric interactions between surface gravity waves yield considerable variations of the wave spectrum. Resonance nonlinear interactions cause the generation of side-frequency wave components and the change of slope statistics of surface gravity and short gravity waves. Thermohaline anomaly is a result of strong simultaneous variations (fluctuations) of sea surface temperature and salinity at localized ocean areas. Ocean internal waves are perfectly observed in radar (SAR) images. Surface manifestations can also be detected using passive microwave radiometers. Gravity wave instabilities and breaking patterns accompanied by the change of the wave slope statistics usually result in an increase of the radio-brightness contrast.
