Abstract. Reconstructing Oligocene–Miocene paleoelevation contributes to our understanding of the evolutionary history European Alps and sheds light on geodynamic Earth surface processes involved in development Alpine topography. Despite being one most intensively explored mountain ranges worldwide, constraints elevation remain scarce. Here we present stable clumped isotope measurements provide...

We analyze the ability of an oceanic monitoring array to detect potential changes in the North Atlantic meridional overturning circulation (MOC). The observing array is ‘deployed’ into a numerical model (ECHAM5/MPI-OM), and simulates the measurements of density and wind stress at 26◦N in the Atlantic. The simulated array mimics the continuous monitoring system deployed in the framework of the U...

The extensive nuclear bomb testing of the fifties and sixties and the final tests in the seventies caused a strong 36Cl peak that has been observed in ice cores worldwide. The measured 36Cl deposition fluxes in eight ice cores (Dye3, Fiescherhorn, Grenzgletscher, Guliya, Huascarán, North GRIP, Inylchek (Tien Shan) and Berkner Island) were compared with an ECHAM5-HAM general circulation model si...

They act as cloud condensation and ice nuclei and may have an influence on the hydrological cycle. Here we investigate a...

The chemistry climate model ECHAM5/MESSy1 (E5/M1) in a setup extending from the surface to 80 km with a vertical resolution of about 600 m near the tropopause with nudged tropospheric meteorology allows a direct comparison with satellite data of chemical species at the same time and location. Here we present results out of a transient 10 years simulation for the period of the Antarctic vortex s...

This study aims at improving the forecast skill of climate predictions through the use of ocean synthesis data as initial conditions of a coupled climate model. For this purpose, the coupled model of the Max Planck Institute for Meteorology, consisting of the atmosphere model ECHAM5 and the ocean model MPI-OM, is initialized with oceanic synthesis fields available from the German contribution t...

[1] The present study examines the precipitation variability over the South Asian monsoon heat low region and associated teleconnections using high resolution (T106L31) climate simulations performed with the ECHAM5 model. It is found that an intensification of the heat low in response to enhanced precipitation/convection over northwestern India‐Pakistan (NWIP) can induce large‐scale circulation...

Temperature, precipitation and wind extremes over Europe are examined in an ensemble of RCA3 regional climate model simulations driven by six different global climate models (ECHAM5, CCSM3, HadCM3, CNRM, BCM and IPSL) under the SRES A1B emission scenario. The extremes are expressed in terms of the 20-yr return values of annual temperature and wind extremes and seasonal precipitation extremes. T...

Climate change impact on water resources (streamflow and deep natural recharge) based on the downscaled outputs from the ECHAM5 general circulation model (GCM) has been investigated in the Mediterranean basin (Fluvià, Spain) for the A2, B1 greenhouse scenarios and 2000–2024/2025–2050 time slices. The HEC-HMS 3.4 rainfall-runoff numerical model was the basic tool used to generate streamflow for ...
