Regional Climate Dynamics
Convenors
Description
This session seeks to achieve a better understanding of past regional climatic and environmental dynamics through comparison of reconstructions and model simulations. Presentations contribute towards a global coverage of high-resolution, well-dated paleoclimatic data, reconstructions of past climate-state parameters (e.g., temperature, precipitation, atmospheric pressure fields), a better understanding of past modes of climate variability and their teleconnections, and of rapid and extreme climate events at the regional scale. The session aims to promote data-model comparisons. Timescales covered encompass the last 130 ka, in particular the time streams of the last glacial-interglacial cycle, the Holocene, and the last 2 ka.
