The first version of the coupled GCM SINTEX-FRSGC
On the natural variability of the pre-industrial climate (2006)
Bengtsson, Lennart, Hodges, K.I., Roeckner, Erich, Brokopf, Renate
We suggest that climate variability in Europe for the “pre-industrial” period 1500–1900 is fundamentally a consequence of internal fluctuations of the climate system. This is because a model...

A dynamical link between the Arctic and the global climate system (2006)
Dethloff, K., Rinke, A., Benkel, A., Koltzow, M., Sokolova, E., Kumar Saha, S., ...
By means of simulations with a global coupled AOGCM it is shown that changes in the polar energy sink region can exert a strong influence on the mid- and high-latitude climate by modulating the...
ENSO impact on midlatitude circulation patterns in future climate change projections (2006)
Mueller, Wolfgang A., Roeckner, Erich
The remote influence of the leading mode of interannual variability in the Tropics, the El Niño/Southern Oscillation (ENSO), on the northern hemispheric midlatitude circulation in future climate is...

Reducing climatology bias in an ocean-atmosphere CGCM with improved coupling physics (2005)
Luo, Jing-Jia, Masson, Sebastien, Roeckner, Erich, Madec, Gurvan, Yamagata, Toshio
The cold tongue in the tropical Pacific extends too far west in most current ocean–atmosphere coupled GCMs (CGCMs). This bias also exists in the relatively high-resolution SINTEX-F CGCM despite its...

Estimating the PPH-bias for simulations of convective and stratiform clouds (2004)
Bäuml, Gerhard, Chlond, Andreas, Roeckner, Erich
The plane parallel homogeneous (PPH) approximation is known to generate systematic errors in the computation of reflectivity and transmissivity of a horizontally inhomogeneous cloud field. This...
Can aerosols spin down the water cycle in a warmer and moister world? (2004)
Liepert, B. G., Feichter, Johann, Lohmann, U., Roeckner, Erich
Surface observations show puzzling evidence of reduced solar warming and concurrent increasing temperature during the last four decades. Based on climate simulations with the general circulation...
Nonlinear aspects of the climate response to greenhouse gas and aerosol forcing (2004)
Feichter, Johann, Roeckner, Erich, Lohmann, Ulrike, Liepert, B.
In a series of equilibrium experiments the climate response to present-day radiative forcings of anthropogenic greenhouse gases and aerosol particles is calculated. The study was performed with a...
The impact of Greenland's deglaciation on the Arctic circulation (2004)
Dethloff, K., Dorn, W., Rinke, A., Fraedrich, Klaus, Junge, Martina, Roeckner, Erich, ...
The influence of Greenland's deglaciation on the atmospheric winter and summer circulation of the Arctic have been quantified with the high-resolution regional atmospheric model HIRHAM4. Greenland's...
Latif, Mojib, Roeckner, Erich, Botzet, Michael, Esch, Monika, Haak, Helmut, Hagemann, Stefan, ...
Sea surface temperature (SST) observations in the North Atlantic indicate the existence of strong multidecadal variability with a unique spatial structure. It is shown by means of a new global...
Roeckner, Erich, Brokopf, Renate, Esch, Monika, Giorgetta, Marko, Hagemann, Stefan, Kornblueh, Luis, ...
The most recent version of the Max Planck Institute for Meteorology atmospheric general circulation model, ECHAM5, is used to study the impact of changes in horizontal and vertical resolution on...
Santer, B. D., Sausen, R., Wigley, T. M. L., Boyle, J. S., AchutaRao, K., Doutriaux, C., ...
We examine changes in tropopause height, a variable that has hitherto been neglected in climate change detection and attribution studies. The pressure of the lapse rate tropopause, p(LRT), is...
The atmospheric general circulation model ECHAM 5. PART I: Model description (2003)
Roeckner, Erich, Bäuml, G., Bonaventura, L., Brokopf, Renate, Esch, Monika, Giorgetta, Marco, ...
A detailed description of the fifth-generation ECHAM model is presented. Compared to the previous version, ECHAM4, a number of substantial changes have been introduced in both the numerics and...
STOIC: a study of coupled model climatology and variability in tropical ocean regions (2002)
Davey, M. K., Huddleston, M., Sperber, K. R., Braconnot, P., Bryan, F., Chen, D., ...
We describe the behaviour of 23 dynamical ocean-atmosphere models, in the context of comparison with observations in a common framework. Fields of tropical sea surface temperature (SST), surface wind...
Cloud fields and concurrent dynamical structures associated with extratropical cyclones in a general circulation model are investigated with emphasis on the cool season (October-March). An ensemble...
Voss, Reinhard, May, Wilhelm, Roeckner, Erich
Changes in variability and extremes of the hydrological cycle are studied in two 30 year simulations using a general circulation model at high horizontal resolution. The simulations represent the...
Forcing of the quasi-biennial oscillation from a broad spectrum of atmospheric waves (2002)
Giorgetta, Marco A., Manzini, Elisa, Roeckner, Erich
[1] The circulation of the stratosphere, and its influence on the trace constituent distribution, is an important component of the climate system, which must be included in simulations of global...
