The area of research of the department for theory and modeling at IAP are the atmospheric layers from the troposphere to the mesosphere and lower thermosphere (MLT). The aim is a better understanding of the climate system and its natural and anthropogenic variability with special consideration of the middle atmosphere. The coupling of atmospheric layers due to dynamic processes results from the vertical propagation of waves and their interaction with the large-scale circulation. Important aspects are radiation transfer and the transport of chemically or radiatively active tracers.
The current activities of the department are summarized with eight research topics. The overall goal is th edevelopmentof new theoretical concepts and their application in own circulation models. On the methodological side we also take advantage of community models, reanalyses and observational data sets.
