Matter transport in meso-scale oceanic fronts of river discharge type

A hybrid model based on the Monte-Carlo method and turbulence model with a third-order closure is developed to forecast transport processes of matter in coastal oceanic fronts of river discharge type. A deterministic part of a particle displacement is modeled with non-linear system of thermodynamic equations. Variations in processes of cooling and heating as well as wind changes are considered as main reasons to govern conditions of the matter transport during a short period of simulation. Distinct diurnal variations of a planar temperature distribution observed by NOAA satellite in the Rhine discharge region are discussed with respect to potentialities of the proposed approach.
