Inherent Dissipation of Upwind‐Biased Potential Temperature Advection and its Feedback on Model Dynamics
(
- Journal of Advances in Modeling Earth Systems
, 2021-03-19)
Higher order upwind‐biased advection schemes are often used for potential temperature advection in dynamical cores of atmospheric models. The inherent diffusive and antidiffusive fluxes are interpreted here as the effect ...
Relationships to Estimate the Magnitude Ms of Historical Earthquakes in Europe from Macroseismic Observations
(2002)
We develop empirical relationships between the surface wave magnitude MS and macroseismic data, i.e. the epicentral intensity I0, isoseismal radii R(I) of different intensities I and the focal depth h. The basis of this ...
Introduction: Historical Earthquakes, Paleoseismology, Neotectonics and Seismic Hazard: New Insights and Suggested Procedures
(2020)
This publication developed from the 5th International Colloquium on “Historical Earthquakes, Paleoseismology, Neotectonics and Seismic Hazard” which was held from 11 to 13 October 2017 at the Federal Institute for Geosciences ...
Relationship between magnitude, macroseismic intensity and distance for induced earthquakes in Germany
(2019)
Induced earthquakes are of public concern and of legal significance if they are felt or if they cause damage. Models to describe the relation between macroseismic intensities, magnitude, and distance from the epicenter or ...
Suche nach dunkler Materie mit den H.E.S.S.-Cherenkov-Teleskopen
(Univ. Hamburg, 2008)
Die Natur der dunklen Materie ist nach wie vor ungeklart und stellt eine der fundamentalsten Fragen der aktuellen Kosmologie dar. In vielen verschiedenen Experimenten wird versucht, diese Teilchen, die sogenannten WIMPs ...
The central parsec of the milky way at 3.8 micrometer
(Univ. Köln, 2008)
The central part of the Milky Way is a unique environment where an interplay of different astrophysical phenomena can be studied, starting from the physics of the interstellar medium, stellar physics and star formation, ...
Evolution of convective characteristics during tropical cyclogenesis
(
- Quarterly Journal of the Royal Meteorological Society
, 2021-04-05)
Four idealized, high‐resolution (500 m horizontal grid spacing), numerical simulations are used to investigate the evolution of convective structures during tropical cyclogenesis. The simulations all begin with a weak ...
Langfristige Variabilität der thermohalinen Zirkulation in einem gekoppelten Ozean-, Meereis-, Atmosphärenmodell
(Univ. Bremen, 1999)
Thermohaline circulation, variability, energy and moisture balance model, paleoceanography. - Freshening of high latitude surface water can change the large scale oceanic transport of heat and salt. Consequently, atmospheric ...
The earthquake of September 3, 1770 near Alfhausen (Lower Saxony, Germany): a real, doubtful, or fake event?
(
- Historical Earthquakes, Paleoseismology, Neotectonics and Seismic Hazard: New Insights and Suggested Procedures
, 2020)
In the weekly newspaper of Osnabrück (Germany) of November 3, 1770, a report about a local earthquake was published. Pastor Buck described ground motion effects in the manor ‘Haus Horst’, 1.5 km away from the village of ...
Predicting Imminence of Analog Megathrust Earthquakes With Machine Learning: Implications for Monitoring Subduction Zones
(
- Geophysical Research Letters
, 2020-03-31)
Subduction zones are monitored using space geodesy with increasing resolution, with the aim of better capturing the deformation accompanying the seismic cycle. Here, we investigate data characteristics that maximize the ...
