Stochastic Dynamics of Sea Surface Height Variability

Sea surface height anomalies measured by the Ocean Topography Experiment (TOPEX)/Poseidon satellite altimeter indicate high values of skewness and kurtosis. Except in a few regions, including the Gulf Stream, the Kuroshio Extension, and the Agulhas Retroflection, that display bimodal patterns of sea surface height variability, kurtosis is uniformly greater than 1.5 times the squared skewness mi...

Depolarization of Electromagnetic Waves By Sea Surface

An improved Two Scale Model (TSM) has been investigated for the depolarization of electromagnetic waves from sea surface. Classical TSM produce depolarized results due to the tilt of reflecting plane. To include the contribution of actual phenomenon we add the second order scattering effects at small scale and develop an improved TSM. Numerical results are obtained for both backscattering and b...

Geometrical Characteristics of Gaussian Sea Waves

In this work, we study some geometrical properties of a stationary Gaussian field modeling the sea surface, using the energy spectrum. We consider the length of a crest and the mean speed of contours, which can be expressed as integrals over level sets. We also give central limit theorems for some of these quantities, using chaos expansions.
