A study into the passive tracer and Lagrangian particles propagation in the coastal area of South-East Baltic

Pages

Abstract

This paper studies the passive tracer and Lagrange particle propagation in the coastal area of South-East Baltic using hydrodynamic numerical modelling. The inclusion of an additional parameter, which describes the variation of the passive tracer concentration as well as its connection with the Lagrange particle random walk model, into the model made it possible to identify the features of the coastal water dynamics during upwelling. The possibilities of the penetration of suspended particles of different origin from the coastal area into the open sea and vice versa are investigated.
