| Zusammenfassung |
| Online coupled mesoscale meteorology atmospheric chemistry models have
undergone a rapid evolution in recent years. Although mainly developed by
the air quality modelling community, these models are also of interest for
numerical weather prediction and regional climate modelling as they can
consider not only the effects of meteorology on air quality, but also the
potentially important effects of atmospheric composition on weather. Two
ways of online coupling can be distinguished: online integrated and online
access coupling. Online integrated models simulate meteorology and chemistry
over the same grid in one model using one main time step for integration.
Online access models use independent meteorology and chemistry modules that
might even have different grids, but exchange meteorology and chemistry data
on a regular and frequent basis. This article offers a comprehensive review
of the current research status of online coupled meteorology and atmospheric
chemistry modelling within Europe. Eighteen regional online coupled models
developed or being used in Europe are described and compared. Topics
discussed include a survey of processes relevant to the interactions between
atmospheric physics, dynamics and composition; a brief overview of existing
online mesoscale models and European model developments; an analysis on how
feedback processes are treated in these models; numerical issues associated
with coupled models; and several case studies and model performance
evaluation methods. Finally, this article highlights selected scientific
issues and emerging challenges that require proper consideration to improve
the reliability and usability of these models for the three scientific
communities: air quality, numerical meteorology modelling (including weather
prediction) and climate modelling. This review will be of particular
interest to model developers and users in all three fields as it presents a
synthesis of scientific progress and provides recommendations for future
research directions and priorities in the development, application and
evaluation of online coupled models. |
