The Planet Simulator is a Model of Intermediate Complexity (MIC) which can be used to run climate and paleo-climate simulations for time scales up to 10 thousand years or more in an acceptable real time. The priorities in development are set to speed, easy handling and portability. Its modular structure allows a problem dependent configuration. Adaptions(More)

The impact of mountains and ice sheets on the large-scale circulation of the world's oceans is investigated in a series of simulations with a new coupled ocean–atmosphere model [Oregon State University–University of Victoria model (OSUVic)], in which the height of orography is scaled from 1.5 times the actual height (at T42 resolution) to 0 (no mountains).(More)
An application of the Planet Simulator is presented to estimate the maximum effect of vegetation on the Earth's climate. Four sets of sensitivity experiments are performed: (1) All vegetation related land surface parameters are changed simultaneously. (2) Only one effect of vegetation on climate is considered: albedo, surface roughness and soil hydrology.(More)
The ability of analysing atmospheric dynamics by idealized experiments using a simplified circulation model is illustrated in three related studies. The investigations focus on the organization of localized strom tracks, their impact on low-frequency variability, and on the response to external thermal forcing. A localized storm track in agreement with(More)
A general circulation model of the Martian Atmosphere is coupled with a 3-dimensional polythermal ice-sheet model of the polar ice caps. With this combination a series of experiments is carried out to investigate the impact of long-term obliquity change on the Martian north polar ice cap (NPC). The behaviour of the NPC is tested under obliquities of y ¼ 15(More)
Maximum entropy production and the strength of boundary layer exchange in an atmospheric general circulation model. * A postprint is a digital draft of a research journal article after it has been peer reviewed. A draft before peer review is called a preprint. Postprints may sometimes be the same as the published version, depending on the publisher.(More)
[1] The low frequency variability of the near surface temperature in a climate simulation is compared with Greenland ice core d 18 O time series during the holocene. The simulation is performed with the coupled CSIRO atmosphere-ocean model under present-day conditions. The variability, analyzed by the detrended fluctuation analysis, reveals power-law(More)
Satellite-based precipitation monitoring at high spatial resolution is crucial for assessing the water and energy cycles at the global and regional scale. Based on the recently released 7th version of the Multi-satellite Precipitation Analysis (TMPA) product of the Tropical Rainfall Measuring Mission (TRMM), and the monthly precipitation data (3B43) are(More)
This discussion paper is/has been under review for the journal Earth System Dynamics (ESD). Please refer to the corresponding final paper in ESD if available. Abstract An analysis of so-called Early Warning Signals (EWS) is proposed to identify the spatial origin of a sudden transition that results from a loss in stability of a current state. EWS, such as(More)
