 | Peter Hjort Lauritzen (pel@ucar.edu) for the poster entitled:
A Stability Analysis of Finite-Volume Advection Schemes Permitting Long Time Steps
by Lauritzen, P. Click here to download the poster as pdf-file. |
Peter is an ASP (Advanced Study Program) postdoc at the National Center for Atmospheric Research in Boulder, Colorado. He got his PhD from the University of Copenhagen where he, in collaboration with the Danish Meteorological Institute, derived and implemented a new dynamics module for HIRLAM that exactly conserved mass of air and tracers.
He is particularly interested in numerical methods for dynamical cores, that is (roughly speaking), algorithms that approximate the solution to the adiabatic frictionless equations of motion for the atmosphere on resolved scales. The present poster is about a fundamental part of the dynamical core: advection. It presents the damping and dispersion properties of several widely used advection schemes; among them the so-called Lin & Rood scheme that is used in several European and American general circulation models. It was demonstrated both theoretically and with a conceptual analysis that the scheme is sensitive to the choice of inner and outer operators applied in the scheme that can lead to increased numerical damping for large Courant numbers. |

 | Sebastian Kopf (s.kopf@iu-bremen.de) for the poster entitled:
Using analogues to assess uncertainty in urbanarea climate relocation
by Kopf, S.; HaDuong, M.; Hallegatte, S. Click here to download the poster as pdf-file. |
| Sebastian is a Bachelor student in Earth and Space Sciences at Jacobs University (formerly International University Bremen), where he will research the impact of siderophores and organic acids on the mobilization of trace and transition elements from igneous and sedimentary rocks for his thesis. His current research in climate change with the Centre International de Recherche sur l’Environnement et le Développement (CIRED) in Paris started as an internship on urban climate relocation, a project that are now expanding to further explore the use of analogues in the visualization of climate change impacts. |

 | Björn Machalett (b.machalett@nakula.de) for the poster entitled:
Dynamics of past aeolian dust deposition in Central Asia: a case study from the loess deposits of southeast Kazakhstan
by Oches, E.A.; Frechen, M.; Zöller, L.
Click here to download the poster as pdf-file. |
Björn is a PhD fellow of the German Federal Environmental Foundation (DBU), working at the University of Bayreuth and the Leibniz Institute of Applied Geosciences, Hannover. The aim of his research, supervised by Prof. L. Zöller and Prof. M. Frechen, is the deduction of Pleistocene atmospheric circulation patterns by studying the past aeolian dust dynamics that are registered in loess sequences of Eurasia. To characterise these dynamics Björn combines highly resolved particle size studies with different geochronological methods. He put a special focus on amino acid geochronology (AAG), which he is carrying out under the supervision of Prof. E.A. Oches at the University of South Florida AAG laboratory. Björn has pointed out that previous discussed circulation models for Eurasia were too simplified and showed that the past aeolian dust record of Eurasia reflects a long-term signal of seasonality, triggered by changes in duration and permanency of the Asiatic polar front. |

Decrease in the Atlantic overturning does not significantly impact oceanic CO2 uptake over century timescale
by Swingedouw, D.; Bopp, L.; Matras, A. Click here to download the poster as pdf-file. |
| Didier Swingedouw has completed his PhD at the "Laboratoire des Sciences du Climat et de l'Environnement" (LSCE) near Paris. He has defended his PhD in November 2006 and is now a European postdoctoral fellow of the NICE project at UCL in Belgium. His research interests are related to the climate dynamics with a multi-disciplinary approach and a focus on the role of the ocean. He has evaluated the origin and the impact of the weakening of the thermohaline circulation under global warming in terms of ocean dynamics, climatic response and oceanic biogeochemical consequences. |
