Projecting Stratocumulus Transitions on the Albedo—Cloud Fraction Relationship Reveals Linearity of Albedo to Droplet Concentrations
; ; ; ; ; ; (Geophysical Research Letters, 2022-10-13)
Satellite images show solid marine stratocumulus cloud decks (Sc) that break up over the remote oceans. The Sc breakup is initiated by precipitation and is accompanied by a strong reduction in the cloud radiative effect. ... -
Pronounced increase in slope instability linked to global warming: A case study from the eastern European Alps
; Comiti, Francesco; (Earth Surface Processes and Landforms, 2021-03-06)
In recent decades, slope instability in high‐mountain regions has often been linked to increase in temperature and the associated permafrost degradation and/or the increase in frequency/intensity of rainstorm events. In ... -
Propagation, linkage, and interaction of caldera ring-faults: comparison between analogue experiments and caldera collapse at Miyakejima, Japan, in 2000
(Bulletin of VolcanologyBulletin of Volcanology, 2009)The formation of ring faults yields important implications for understanding the structural and dynamic evolution of collapse calderas and potentially associated ash-flow eruptions. Caldera collapse occurred in 2000 at ... -
Properties of quasistellar objects and their progenitors in the radio and mm wavelength regimes in the context of ULIRG-to-QSO evolution
(Univ. Köln, 2010)The thesis at hand presents the results of a study of galaxies with active galactic nuclei (AGN) carried out in the radio and mm wavelength regimes at low and high angular resolutions. The studied objects cover a broad ... -
Properties of Turbulent Alfvénic Fluctuations and Wave‐Particle Interaction Associated With Io's Footprint Tail
; ; ; ; (Journal of Geophysical Research: Space Physics, 2022-12-09)
We investigate the small‐scale magnetic field fluctuations and their associated turbulent nature in the Io flux tube (IFT) connected to Io's footprint tail (IFPT). Our study is based on the recent magnetic field measurements ... -
Properties of turbulent star-forming clusters - models versus observations
(Univ. Potsdam, 2006)Sterne entstehen im Inneren von turbulenten Molekülwolken, die unter dem Einfluss ihrer eigenen Gravitation fragmentieren und kollabieren. So entsteht ein Sternhaufen aus hundert oder mehr Objekten. Der Sternentstehungsprozess ... -
Protomylonite evolution potentially revealed by the 3D depiction and fractal analysis of chemical data from a feldspar
(Contributions to Mineralogy and Petrology, 2014)An alkali feldspar megacryst from a protomylonite has been studied using laser ablation-ICP-mass spectrometry combined with cathodoluminescence imaging, Raman spectroscopy, and electron probe microanalysis. The aim was to ... -
Provenance and Weathering of Clays Delivered to the Bay of Bengal During the Middle Miocene: Linkages to Tectonics and Monsoonal Climate
; ; ; ; ; ; ; ; ; ; (Paleoceanography and Paleoclimatology, 2021-02-24)
Tectonics and regional monsoon strength control weathering and erosion regimes of the watersheds feeding into the Bay of Bengal, which are important contributors to global climate evolution via carbon cycle feedbacks. The ... -
Provenance of lower Palaeozoic metasediments of the East Odenwald (Mid-German-Crystalline Zone, Variscides)—a correlation with the East European Platform (Poland)
(International Journal of Earth Sciences, 2021-09-21)U–Pb age spectra of detrital zircons related to the East European Platform could be traced in paragneiss through the whole Mid-German-Crystalline Zone (Variscides, Central Europe) from the Odenwald via the Spessart to the ... -
Provenance of Pleistocene Rhine River Middle Terrace sands between the Swiss–German border and Cologne based on U–Pb detrital zircon ages

Provenance of the Bosnian Flysch
Mikes, Tamás; Christ, Dominik; Petri, Rüdiger;; Frei, Dirk; Báldi-Beke, Mária; ; ; Hrvatović, Hazim; Eynatten, Hilmar (Swiss Journal of Geosciences, 2008)
Sandwiched between the Adriatic Carbonate Platform and the Dinaride Ophiolite Zone, the Bosnian Flysch forms a c. 3000 m thick, intensely folded stack of Upper Jurassic to Cretaceous mixed carbonate and siliciclastic ... -
Provenienzanalyse an paläozoischen Metasedimenten der Ostalpen mit Schwerpunkt in der Nördlichen Grauwackenzone - Petrographie, Glimmerchemie, 40Ar/39Ar-Datierungen
(Univ. Halle, 2006)Für die vorliegende Arbeit wurden aus dem alpinen Paläozoikum im Westabschnitt der Nördlichen Grauwackenzone schwachgradig metamorphe klastische Sedimentgesteine untersucht. Anhand der Sedimentpetrographie sowie der ... -
Proximate causes of deforestation in the Bolivian lowlands: an analysis of spatial dynamics
Müller, Robert;; Schierhorn, Florian; Gerold, Gerhard; Pacheco, Pablo (Regional Environmental Change, 2011)
Forests in lowland Bolivia suffer from severe deforestation caused by different types of agents and land use activities. We identify three major proximate causes of deforestation. The largest share of deforestation is ... -
