Influence of Volatiles on Mass Wasting Processes on Vesta and Ceres
(
- Journal of Geophysical Research: Planets
, 2021-03-19)
We have analyzed mass wasting features, their distribution and deposit geometry on the two largest main asteroid belt objects—protoplanet Vesta and dwarf planet Ceres—and compared their geomorphology and mobility. Both ...
A cold pool perturbation scheme to improve convective initiation in convection‐permitting models
(
- Quarterly Journal of the Royal Meteorological Society
, 2021-05-04)
Cold pools originate from evaporation in precipitating downdraughts and spread as density currents at the surface. Vertical motion at the leading edge of the cold pool is an important trigger for new convective cells in ...
Lösung der Grenzflächenproblematik bei der gemeinsamen Inversion geoelektrischer und seismischer Daten von oberflächennahen, porösen Schichten
(Univ. Bochum, 2001)
Bisherige Ansätze Daten aus Seismik und Geoelektrik durch einen Joint Inversionsalgorithmus zu interpretieren schlagen oftmals fehl, da sowohl die Tiefen und Formen der Grenzflächen als auch die Grenzflächenanzahl für die ...
Heavy Metal and Rock in Space: Cluster RAPID Observations of Fe and Si
(
- Journal of Geophysical Research: Space Physics
, 2021-03-22)
Metallic and silicate ions carry essential information about the evolution of the Earth and near‐Earth small bodies. Despite this, there has so far been very little focus on ions with atomic masses higher than oxygen in ...
Modern solar facilities - advanced solar science
(
- Universitätsverlag Göttingen, Göttingen
, 2007)
An international workshop entitled: Modern Solar Facilities - Advanced Solar Science was held in Göttingen from September 27 until September 29, 2006. The workshop, which was attended by 88 participants from 24 different ...
Modelling the Earth's magnetic field of magnetospheric origin from CHAMP data
(
- Scientific Technical Report / Geoforschungszentrum Potsdam
, 2004)
As observed on the Earth's surface, the magnetic field can be separated into three components: The "Main Field", the "Crustal Field"; and the "External Magnetic Field". This work concentrates on the magnetospheric current ...
First Studies of Mesosphere and Lower Thermosphere Dynamics Using a Multistatic Specular Meteor Radar Network Over Southern Patagonia
(
- Earth and Space Science
, 2021-02-23)
This paper presents for the first time results on winds, tides, gradients of horizontal winds, and momentum fluxes at mesosphere and lower thermosphere altitudes over southern Patagonia, one of the most dynamically active ...
Investigation of the properties of iron-bearing alloys and silicates and their implications for the Earth's lower mantle and core
(Univ. Bayreuth, 2009)
(1) (Mg,Fe)(Si,Al)O3 perovskite comprises about 80% of the Earth's lower mantle by volume, leaving ~ 15% to (Mg,Fe)O ferropericlase and ~ 5% to CaSiO3 perovskite. Therefore characteristics of the lower mantle would be ...
A comparison of Bayesian hierarchical space-time models for earthquake data
(2004)
Stochastic earthquake models are often based on a marked point process approach as for instance presented in Vere-Jones (1995). This gives a fine resolution both in space and time making it possible to represent each ...
Unsteady thermal convection in the North-East German Basin
(
- WIAS, Berlin
, 2002)
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 ...
