The research proposal will determine climate dynamics due to analysis of climate anomalies during the last 10.000 years. This will be done by combining two unique climate archives (documentary data back to 1.000 AD, dendrochronological data back 10.000 BP). With this approach the climate dynamics can be studied on a long time scale. Time series for key climatic parameters will be modelled by applying a transfer function. The modelled results allow a reconstruction of climate dynamic processes which led to extreme floods and precipitation anomalies. The determination of climate variability enables the possibility to differentiate between human and natural driving forces of sudden climate changes and will help to understand future climate changes.

该研究计划将通过分析过去一万年的气候异常来确定气候动态。这将通过结合两个独特的气候档案（可追溯到公元 1000 年的文献数据，可追溯至距今 10000 年的树木年代学数据）来完成。通过这种方法，可以长期研究气候动态。关键气候参数的时间序列将通过应用传递函数进行建模。模拟结果可以重建导致极端洪水和降水异常的气候动态过程。气候变率的确定使得能够区分气候突然变化的人类驱动力和自然驱动力，并将有助于了解未来的气候变化。
