Abstract

Analysis of Saharan Dust Transport Using the Eta Model Guest contribution Z Vukmirovic*, M. Unkasevic^, L Lazic^, I Tosic^ and M. Tasic* 'institute of Physics, Belgrade University, Pregrevica 118, YU-IIOSOBelgrade-Zemun ^ Institute of Meteorology, Belgrade University, Dobracina 16, YU-11000 Belgrade The construction of three-dimensional atmospheric trajectories provides a valuable diagnostic tool for illustrating and studying three-dimensional flow fields and associated transport. Trajectories were calculated using the three- dimensional, limited area primitive equation Eta model with step-mountain coordinates (Mesinger 1984; Mesinger et al, 1988; Janjic 1990; Janjic 1994). Calculation of trajectories The horizontal wind components (%, v) from the Eta model are defined on a latitude-longitude (X,cp) grid, and the vertical component of motion r\ = drj / dt is defined at interfaces at points staggered with respe
