Understanding Micropolar Theory in the Earth Sciences I: The Eigenfrequency $\omega_r$
(Pure and Applied Geophysics, 2021-12-25)Even though micropolar theories are widely applied for engineering applications such as the design of metamaterials, applications in the study of the Earth’s interior still remain limited and in particular in seismology. ... -

Understanding Micropolar Theory in the Earth Sciences II: The Seismic Moment Tensor
(Pure and Applied Geophysics, 2021-11-05)Seismic events produced by block rotations about vertical axis occur in many geodynamic contexts. In this study, we show that these rotations can be accounted for using the proper theory, namely micropolar theory, and a ... -
Understanding summer wind systems over the eastern Mediterranean in a high‐resolution climate simulation
(International Journal of Climatology, 2022-06-23)Regional and local wind systems are often complex, particularly near coastal areas with a highly variable orography. Thus, the realistic representation of regional wind systems in weather and climate models is of strong ... -
Understanding the Extreme Spread in Climate Sensitivity within the Radiative-Convective Equilibrium Model Intercomparison Project
(Journal of Advances in Modeling Earth Systems, 2020)The Radiative-Convective Equilibrium Model Intercomparison Project (RCEMIP) consists of simulations at three fixed sea-surface temperatures (SSTs: 295, 300, and 305 K) and thus allows for a calculation of the climate ... -
Unmanned aerial vehicle-based mapping of turf-banked solifluction lobe movement and its relation to material, geomorphometric, thermal and vegetation properties
(Permafrost and Periglacial Processes, 2020)Solifluction is one of the most widespread periglacial processes with low annual movement rates in the range of —millimeters to centimeters. Traditional methods to assess solifluction movement usually have low spatial ... -
Unpacking future climate extremes and their sectoral implications in western Nepal
(Climatic Change, 2021-09-19)Existing climate projections and impact assessments in Nepal only consider a limited number of generic climate indices such as means. Few studies have explored climate extremes and their sectoral implications. This study ... -
Unravelling the lithospheric-scale thermal field of the North Patagonian Massif plateau (Argentina) and its relations to the topographic evolution of the area
(International Journal of Earth Sciences, 2020-11-27)The North Patagonian Massif (NPM) area in Argentina includes a plateau of 1200 m a.s.l. (meters above sea level) average height, which is 500–700 m higher than its surrounding areas. The plateau shows no evidence of internal ... -
Unsteady thermal convection in the North-East German Basin
(WIAS, Berlin2002)We describe a Voronoi box based finite volume method for the numerical simulation of thermal convection in sedimental basins. The method shows a temperature maximum principle and consistent velocity approximation. We present ... -

Untersuchung der Partikel-Lagrangeschen Advektionsmethode anhand von meteorologisch relevanten Beispielen
(Univ. Frankfurt (Main), 2001)Diese Arbeit beschreibt Entwürfe zur Anwendung einer nicht-interpolierenden Advektionsmethode in numerischen Wettervorhersagemodellen. Es wird an verschiedenen Beispielen dargestellt, in welcher Weise eine solche ... -
Untersuchung der Photooxidantien Wasserstoffperoxid, Methylhydroperoxid und Formaldehyd in der Troposphäre der Antarktis
(Univ. Bremen, 2001)Photooxidants play an important role for the oxidation capacity of the troposphere. The presented work deals with seasonal changes of atmospheric photooxidants like hydrogen peroxide (H2O2), methylhydroperoxide (MHP) and ... -
Untersuchungen zur Gaschemie und Anwendbarkeit isotopischer Geothermometrie an hydrothermalen Systemen des mittelatlantischen Rückens
(Univ. Hamburg, 2009)In der vorliegenden Arbeit wurde untersucht, welche Parameter die Anwendbarkeit der Geothermometer für Wasserstoff, im System Wasserstoff/ Methan/ Wasser, und Kohlenstoff, im System Methan/ Kohlendioxid, bestimmen. Dazu ... -
Untersuchungen zur Geschwindigkeitsstruktur im unteren Erdmantel und im Bereich der Kern-Mantei-Grenze unterhalb des Pazifiks mit Scherwellen
(Institut für Meteorologie und Geophysik, Johann Wolfgang Goethe-Universität Frankfurt am Main, 1990)In der vorliegenden Arbeit werden anomale Laufzeitdifferenzen zwischen den Mantel- und Kernphasen S, Sdiff, SKS und SKKS mit lateralen Geschwindigkeitsperturbationen gegenüber dem Standarderdmodell PREM erklärt. Das ... -
