A Binomial Stochastic Framework for Efficiently Modeling Discrete Statistics of Convective Populations
(Journal of Advances in Modeling Earth Systems, 2021-03-23)Understanding the coupling between convective clouds and the general circulation, as well as addressing the gray zone problem in convective parameterization, requires insight into the genesis and maintenance of spatial ... -
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 ... -
A Combined Neural Network‐ and Physics‐Based Approach for Modeling Plasmasphere Dynamics
(Journal of Geophysical Research: Space Physics, 2021-03-16)In recent years, feedforward neural networks (NNs) have been successfully applied to reconstruct global plasmasphere dynamics in the equatorial plane. These neural network‐based models capture the large‐scale dynamics of ... -
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 ... -
A Comparison of Radial Diffusion Coefficients in 1‐D and 3‐D Long‐Term Radiation Belt Simulations
(Journal of Geophysical Research: Space Physics, 2021-08-13)Radial diffusion is one of the dominant physical mechanisms driving acceleration and loss of radiation belt electrons. A number of parameterizations for radial diffusion coefficients have been developed, each differing in ... -
A Comparison of the Location of the Mid‐Latitude Trough and Plasmapause Boundary
(Journal of Geophysical Research: Space Physics, 2021-04-15)Abstract: We have compared the location of the mid‐latitude trough observed in two dimensional vertical total electron content (vTEC) maps with four plasmapause boundary models, Radiation Belt Storm Probes (RBSP) observations, ... -
A comprehensive model of seismic velocities for the Bay of Mecklenburg (Baltic Sea) at the North German Basin margin: implications for basin development
(Geo-Marine Letters, 2021-04-15)The geometry of sedimentary basins is normally described by the interpretation of seismic reflectors. In addition to that, rock properties of the sedimentary successions between these reflectors give further insight into ... -
A Comprehensive Study of Infrasound Signals Detected from the Ingolstadt, Germany, Explosion of 1 September 2018
(Pure and Applied Geophysics, 2020-02-19)The explosion at the Ingolstadt oil refinery was widely recorded at seismic and infrasound stations deployed throughout Central Europe, to distances of several hundred to a thousand kilometres. This study focuses on the ... -
A concept for a regional coastal zone mission
(Univ. Berlin, 2002) -
A contribution to characterizing and calibrating the pointing control system of the SOFIA telescope
(Univ. Stuttgart, 2009)SOFIA, the Stratospheric Observatory for Infrared Astronomy, is an airborne observatory that will study the universe in the infrared spectrum. A Boeing 747-SP aircraft will carry a 2.5 m telescope designed to make sensitive ... -
A Coulomb Stress Response Model for Time‐Dependent Earthquake Forecasts
(Journal of Geophysical Research: Solid Earth, 2022-08-31)Seismicity models are probabilistic forecasts of earthquake rates to support seismic hazard assessment. Physics‐based models allow extrapolating previously unsampled parameter ranges and enable conclusions on underlying ... -
A Critical Evaluation of Deep Blue Algorithm Derived AVHRR Aerosol Product Over China
(Journal of Geophysical Research: Atmospheres, 2019)The Deep Blue (DB) aerosol retrieval algorithm has recently been applied to Advanced Very High Resolution Radiometer (AVHRR) data to produce a first version (V001) of a global aerosol optical thickness (AOT) data set. In ... -
A Decentralized Approach for Modeling Organized Convection Based on Thermal Populations on Microgrids
(Journal of Advances in Modeling Earth Systems, 2022-10-26)In this study, a spectral model for convective transport is coupled to a thermal population model on a two‐dimensional horizontal “microgrid,” covering the typical gridbox size of general circulation models. The goal is ... -
A Detailed, Multi‐Scale Assessment of an Atmospheric River Event and Its Impact on Extreme Glacier Melt in the Southern Alps of New Zealand
(Journal of Geophysical Research: Atmospheres, 2021-05-02)North‐westerly airflow and associated atmospheric rivers (ARs) have been found to profoundly influence New Zealand’s west coasts, by causing flooding, landslides and extreme ablation and accumulation on glaciers in the ... -
A fourth order split scheme for elastic wave propagation
(Humboldt-Univ., Berlin2007)Motivated by seismological problems we have studied a 4th order split scheme for the elastic wave equation. We split in the spatial directions and obtain locally one-dimensional systems to be solved. We have analyzed the ... -
A ground motion logic tree for seismic hazard analysis in the stable cratonic region of Europe: regionalisation, model selection and development of a scaled backbone approach
(Bulletin of Earthquake Engineering, 2020-08-29)Regions of low seismicity present a particular challenge for probabilistic seismic hazard analysis when identifying suitable ground motion models (GMMs) and quantifying their epistemic uncertainty. The 2020 European Seismic ... -
