Advanced algorithms for studying the impact of climate changes on ozone levels in the atmosphere
The impact of the increased temperature on some pollution levels is studied by developing climate scenarios and by running them on a period of 16 consecutive years. The mathematical model used in the experiments is a system of nonlinear partial differential equations (PDEs) and the space domain contains the whole of Europe together with some of its surroundings. Difficult computational problems arise after the direct discretisation of the spatial derivatives in the equations. The enormous computational problems can be treated successfully only by resolving five important tasks: 1) applying accurate and efficient numerical algorithms; 2) selecting an appropriate splitting procedure; 3) developing parallel codes; 4) using high-speed computers; 5) exploiting well the cache memories of the parallel computers. Numerical results will be presented in order to illustrate both the efficiency of the code and the fact that the future climate changes will result in consistent increase of some pollution levels.
期刊介绍:
IJEP provides an international forum in the field of environment and pollution and addresses early and medium-term challenges involving scientific prediction, modelling and assessment. It focuses on ground-breaking research in the science of environmental pollution, at the early scientific stage. It is one of three key journals which together offer complete coverage of environmental issues: IJETM focuses on technical/engineering, policy and management solutions for environmental problems, and IJGEnvI focuses on future, longer-term environmental scenarios, ecological economics, climate change and biodiversity.
