Temporal Modulation of the Local Microseism in the North Sea
(
- Journal of Geophysical Research: Solid Earth
, 2020)
Primary and secondary microseism originating in the world oceans and peaking at around 14 and 7 s, respectively, characterize the Earth's background noise in that frequency range. Microseism generated in marginal seas with ...
Permeability estimation from induced polarization: an evaluation of geophysical length scales using an effective hydraulic radius concept
(
- Near Surface Geophysics
, 2019)
Geophysical length scales defined from induced-polarization measurements can be used in models of permeability (k) prediction. We explore the relative merit of different induced-polarization parameters as proxies of an ...
The Role of the SO 2 Radiative Effect in Sustaining the Volcanic Winter and Soothing the Toba Impact on Climate
(
- Journal of Geophysical Research: Atmospheres
, 2020)
Volcanic eruptions are an important climate driver. The impact of Pinatubo-sized eruptions has been observed and is well constrained. The magnitude and duration of volcanic winter effects after supereruptions such as Toba ...
Evolution of an Atmospheric Kármán Vortex Street From High-Resolution Satellite Winds: Guadalupe Island Case Study
(
- Journal of Geophysical Research: Atmospheres
, 2020)
Vortex streets formed in the stratocumulus-capped wake of mountainous islands are the atmospheric analogues of the classic Kármán vortex street observed in laboratory flows past bluff bodies. The quantitative analysis of ...
Effects of Topography and Realistic Drag on the Southern Hemisphere Midlatitude Jet in a Dry Model
(
- Journal of Advances in Modeling Earth Systems
, 2020)
Climate models have substantial biases in the climatological latitude of the Southern Hemisphere eddy-driven jet and the time scale of annular mode variability and disagree on the jet response to climate change. Zonally ...
Probabilistic Models Significantly Reduce Uncertainty in Hurricane Harvey Pluvial Flood Loss Estimates
(
- Earth's Future
, 2019-04-09)
Pluvial flood risk is mostly excluded in urban flood risk assessment. However, the risk of pluvial flooding is a growing challenge with a projected increase of extreme rainstorms compounding with an ongoing global urbanization. ...
Evolution und Struktur des Oberrheingrabens
(Univ. Freiburg (Breisgau), 2006)
In der Modellstudie wurde ein numerisches Modell für ein kontinentales Riftsystem erstellt, welches durch präexistierende Störungen sowohl entlang in seinem Streichen als auch quer dazu vorgeƯzeichnet war. Das Modell ...
Hochgeschwindigkeits-Einschläge von Asteroiden, Kometen und Meteoriten
(Univ. Braunschweig, 2006)
In dieser Arbeit werden physikalische Prozesse von Hoch-Geschwindigkeitseinschlägen auf planetaren Körpern studiert. Zuerst wird innerhalb einer semi-analytischen Näherung für die Hydrodynamik ein kinetisches Modell der ...
Neogene seismotectonics of the south-central Chile margin
(Univ. Potsdam, 2007)
The Andean orogen is the most outstanding example of mountain building caused by the subduction of oceanic below continental lithosphere. The Andes formed by the subduction of the Nazca and Antarctic oceanic plates under ...
Imaging of Cenozoic climatic events and bottom water activities at the northeastern flank of Walvis Ridge: A correlation of seismic data with borehole data measurements
(Univ. Bremen, 2008)
Seismic, marine, walvis ridge, bottom currents, climatic events. - The history of sedimentation and current activities at the northeastern flank of Walvis Ridge is investigated by a correlation of multichannel seismic data ...
