✦ Synopsis

A Lagrangian trajectory model of atmospheric dispersion using the Langevin equation is implemented on a parallel processing computer system, ANUPAM developed at Bhabha Atomic Research Centre, Bombay, India. In the eight-node system with MIMD architecture, a speed-up of 7.22 was achieved using appropriate load balancing between the host node and other nodes. The concentration distribution obtained using the model for two typical cases: (a) high wind shear, low wind speed stable conditions, and (b) low shear, high wind speed unstable conditions, are illustrated with SODAR data as input.

Stochastic models of turbulent atmospheric dispersion treat either the particle displacement or particle velocity as a continuous time Markov process. An analysis of these processes using stochastic differential equation theory shows that previous particle displacement models have not correctly simu
