Abstract

Towards making advection-diffusion solvers as fast as Gaussian ones: a proposal for atmospheric pollution C.L. Vazquez Centra de Cdlculo, Facultad de Ingenieria, Montevideo, Uruguay ABSTRACT: Based on the K-model, an alternative solution to the problem of forecasting atmospheric pollution other than the Gaussian models (either the plume or the puff) is presented It is intended to show its possible use for the long-term as well as for the real-time forecast My proposed procedure is expected to take similar computer time to Gaussian models, thereby eliminating the main objection for its use. Key word index: advection- diffusion solver, atmospheric diffusion, real-time forecast, air pollution 1. INTRODUCTION: It is well known that the Gaussian models have been and still are of widespread use in the analysis of the advection of pollutants. The main advantage of Gaussian models is that they are simple and economical as far as computer-time is concerned. These advant
