An application of WKBJ theory for triad interactions of internal gravity waves in varying background flows
(Quarterly Journal of the Royal Meteorological Society, 2021-01-22)Motivated by the question of whether and how wave–wave interactions should be implemented into atmospheric gravity‐wave parametrizations, the modulation of triadic gravity‐wave interactions by a slowly varying and vertically ... -
An Asthenospheric Upwelling Beneath Central Mongolia — Implications for Intraplate Surface Uplift and Volcanism
(Acta Geologica Sinica ‐ English Edition, 2021-11-27)Intraplate processes, such as continental surface uplift and intraplate volcanism, are enigmatic and the underlying mechanisms responsible are not fully understood. Central Mongolia is an ideal natural laboratory for ... -
An Empirical Model of the Equatorial Electron Pitch Angle Distributions in Earth's Outer Radiation Belt
(Space Weather, 2022-09-20)In this study, we present an empirical model of the equatorial electron pitch angle distributions (PADs) in the outer radiation belt based on the full data set collected by the Magnetic Electron Ion Spectrometer (MagEIS) ... -
An endless summer: 2018 heat episodes in Europe in the context of secular temperature variability and change
(International Journal of Climatology, 2020)The year 2018 was affected by very long-lasting, stable summer conditions in vast parts of Europe, in many regions already starting in April and lasting until October. We investigate the thermal characteristics of this ... -
An Energy Conserving Vlasov Solver That Tolerates Coarse Velocity Space Resolutions: Simulation of MMS Reconnection Events
(Journal of Geophysical Research: Space Physics, 2022-02-11)Vlasov solvers that operate on a phase‐space grid are highly accurate but also numerically demanding. Coarse velocity space resolutions, which are largely unproblematic in particle‐in‐cell (PIC) simulations, can lead to ... -
An evaluation of operational and research weather forecasts for southern West Africa using observations from the DACCIWA field campaign in June–July 2016
(Quarterly Journal of the Royal Meteorological Society, 2020)Reliable and accurate weather forecasts, particularly those of rainfall and its extremes, have the potential to improve living conditions in densely populated southern West Africa (SWA). The limited availability of ... -
An Improved Model of the Earth’s Static Gravity Field Solely Derived from Reprocessed GOCE Data
(Surveys in Geophysics, 2021-01-18)After it was found that the gravity gradients observed by the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite could be significantly improved by an advanced calibration, a reprocessing project ... -
An innovative seismic risk assessment method and implications of strain rate-dependency on risk estimates
(2006)Eine probabilistische Methodologie zur Abschätzung des Erdbebenrisikos bei den bestehenden Gebäuden wurde präsentiert. Diese Methodologie erfasst Analysen der Erdbebengefährdung, der Bauwerksantwort, der Bauwerkschaden und ... -
Analyse und Konzeption von Messstrategien zur Erfassung der bodenhydraulischen Variabilität
(Univ. Dresden, 2007)Die Berücksichtigung der flächenhaften bodenhydraulischen Variabilität gilt bei der Modellierung von Wasser- und Stofftransportprozessen als problematisch. Dies liegt vorrangig an ihrer Erfassung, die kosten- und zeitintensiv ... -
Analyse von Bathymetrie und akustischer Rückstreuung verschiedener Fächersonar- und Sedimentecholot-Systeme zur Charakterisierung und Klassifizierung des Meeresbodens am Gakkel-Rücken, Arktischer Ozean
(Univ. Bremen, 2008)Im ersten Kapitel erfolgt nach der Zielsetzung und Motivation für die vorliegende Dissertation eine kurze geographische Beschreibung des Arktischen Ozeans und dessen tektonischer Entwicklung.Das Augenmerk gilt dabei dem ... -
Analyse von Telemetriesignalen und Radar-Rückstreusignalen zur Rekonstruktion von Bahnstörungen interplanetarer Raumsonden am Beispiel der simulierten Abstiegsdynamik der Huygens-Sonde
(Univ. Bochum, 2004)Die Cassini/Huygens-Mission ist ein gemeinsames Unternehmen von NASA und ESA, mit dem Ziel, das Saturnsystem zu erkunden. Die vorliegende Arbeit ist im Rahmen des Doppler-Wind-Experiments durchgeführt worden. Das Ziel der ... -
Analysis of Compound Climate Extremes and Exposed Population in Africa Under Two Different Emission Scenarios
(Earth's Future, 2020)It is well established that Africa is particularly exposed to climate extremes including heat waves, droughts, and intense rainfall events. How exposed Africa is to the co-occurrence of these events is however virtually ... -
Analysis of future changes in meteorological drought patterns in Fulda, Germany
(International Journal of Climatology, 2020)Meteorological droughts have large impacts on society and the environment. A better understanding and quantification of their occurrences can be highly relevant for the development of proper climate change mitigation, ... -
Analysis of the Thermodynamic Phase Transition of Tracked Convective Clouds Based on Geostationary Satellite Observations
(Journal of Geophysical Research: Atmospheres, 2020)Clouds are liquid at temperature greater than 0°C and ice at temperature below −38°C. Between these two thresholds, the temperature of the cloud thermodynamic phase transition from liquid to ice is difficult to predict and ... -
Analytical Solutions for Gravity Changes Caused by Triaxial Volumetric Sources
(Geophysical Research Letters, 2022-04-18)Volcanic crises are often associated with magmatic intrusions or the pressurization of magma chambers of various shapes. These volumetric sources deform the country rocks, changing their density, and cause surface uplift. ... -
Analyzing Internal Variability and Forced Response of Subdaily and Daily Extreme Precipitation Over Europe
