• Tropical impacts on Mediterranean climate variability Prof. Dr. J. Jacobeit ()

    Analysing tropical impacts on Mediterranean climate variability is the general aim of this recent project. The focus on the Mediterranean region results from its character as a key region in a particular way: regional climate processes not only reflect variability of both, extratropical and tropical circulation, but also the effects of their interactions and particular teleconnections like the impacts of the Asian monsoon or the El-Niño-Southern-Oscillation on Mediterranean climate. The recently started MedCLIVAR (Mediterranen climate variability and predictability) programme under the umbrella of the international research project CLIVAR (Climate Variability and Predictability) shows the increasing efforts for a better understanding of Mediterranean climate and circulation dynamics. In this context requirements for future research are mentioned which induced the scientific development of this project.

    First a teleconnection analysis of Mediterranen precipitation fields will provide indications of tropical impacts on Mediterranean precipitation variability. Particularly teleconnections with the Asian and African monsoon systems will be taken into account. For this purpose statistical methods like correlation analysis, multiple regression and canonical correlation analyses will be applied. In a second step the role of tropical-extratropical interactions in affecting Mediterranean precipitation variability in terms of heavy rain events and thunderstorms will be highlighted. For instance, applying Extended PCA on atmospheric pressure fields accompanying extreme precipitation events should give a better insight into circulation dynamics as a reason for their occurrence. The results of both steps have to be compared and evaluated for substantial agreements. Whether teleconnection analyses are able to identify tropical-extratropical interactions will be an interesting aspect concerning methodological discussions.

    This pre-study, commissioned by the Bavarian “Landesamt für Umwelt” and conducted by the University of Bayreuth, aims at investigating the existing knowledge with respect to Bavaria, identifying research deficits, and developing suggestions for a future orientation of the Bavarian climate research including research capacities at universities and research centres. The study is subdivided into the core areas “Processes relevant for climate” and “Impacts of climate change”. The consortium consists of:

  • Flood History of Northern Alpine rivers Prof. Dr. K.-F. Wetzel Prof. Dr. J. Jacobeit ()
    The flood history of the German Alpine foreland has not previously been examined in detail, even though reliable historical data up to the 13th century are available. Additionally continuous water-level records from 1826 up to the present are available for different river systems in Bavaria. The aim of the current project is to reconstruct the flood history of the Alpine foreland as well as the related atmospheric circulation patterns. By means of the written evidence it can be shown that most of the floods occurred during the summer, obviously caused by a “Zugstrasse Vb” pressure distribution associated with a meridional atmospheric circu­lation mode. This specific atmospheric circulation pattern is affecting large areas of Central Europe, in the north of the Alps as well as in the south. Therefore, the flood history of the Alpine foreland of Germany can be seen as a history of this far-reaching pressure configuration, leading to a better under­standing of the summer conditions in Central Europe.

  • Stadtplan für barrierefreie Mobilität Prof. Dr. Gerd Peyke ()
    Menschen, die in ihrer Mobilität eingeschränkt sind, haben im Alltag oft mit Barrieren zu kämpfen. Der ‚Stadtplan für barrierefreie Mobilität’ stellt für Menschen mit Mobilitätsbehinderung eine Hilfestellung dar, indem er in einem speziellen Web-Interface Barrieren und für sie hilfreiche Einrichtungen für die Innenstadt von Augsburg aufzeigt. Die Anwendung dient als Forschungsplattform, um auf spezielle Nutzergruppen angepasste Internetkartendienste hinsichtlich technischer Gestaltung, Informationsarchitektur und Usability zu untersuchen.
