When Does the Lorenz 1963 Model Exhibit the Signal‐To‐Noise Paradox?
; ; (Geophysical Research Letters, 2021-02-19)
Seasonal prediction systems based on Earth System Models exhibit a lower proportion of predictable signal to unpredictable noise than the actual world. This puzzling phenomena has been widely referred to as the signal‐to‐noise ... -
When There Is No Offset: A Demonstration of Seismic Diffraction Imaging and Depth-Velocity Model Building in the Southern Aegean Sea
; ; ; (Journal of Geophysical Research: Solid Earth, 2020)
A vast majority of marine geological research is based on academic seismic data collected with single-channel systems or short-offset multichannel seismic cables, which often lack reflection moveout for conventional velocity ... -
Whole Atmosphere Model Simulations of Ultrafast Kelvin Wave Effects in the Ionosphere and Thermosphere
; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2020)
The response of the upper atmosphere to equatorial Kelvin waves with a period of ∼3 days, also known as ultrafast Kelvin waves (UFKWs). The whole atmosphere model Ground-to-topside model of Atmosphere and Ionosphere for ... -
Will dairy cattle production in West Africa be challenged by heat stress in the future?
; ; ; ; (Climatic Change, 2020-05-15)
This study focuses on heat stress conditions for dairy cattle production in West Africa under current and future climatic conditions. After testing the accuracy of the dynamically downscaled climate datasets for simulating ... -
Wind Power Input to Ocean Near‐Inertial Waves Diagnosed From a 5‐km Global Coupled Atmosphere‐Ocean General Circulation Model
; (Journal of Geophysical Research: Oceans, 2023-02-14)
Using the 5 km coupled general circulation model ICON, the surface internal wave energy source, crucial for the oceanic circulation, is quantified as the wind‐induced wave energy flux that radiates from the mixed layer ... -
Wind turbine induced seismic signals: the large-scale SMARTIE1 experiment and a concept to define protection radii for recording stations
; Zieger, Toni; Ritter, Joachim; Korn, Michael (Near Surface Geophysics, 2020)
Wind turbines produce mechanical energy that can propagate to the ground and disturb sensitive measurements such as seismic recordings. The aim of the large-scale experiment Seismic Monitoring And Research of wind Turbine ... -
WRF‐based dynamical downscaling of ERA5 reanalysis data for High Mountain Asia: Towards a new version of the High Asia Refined analysis
; Tolksdorf, Vanessa; ; (International Journal of Climatology, 2020-06-18)
The High Asia Refined analysis (HAR) is a regional atmospheric data set generated by dynamical downscaling of the Final operational global analysis (FNL) using the Weather Research and Forecasting (WRF) model. It has been ... -
X-ray and optical properties of X-ray luminous active galactic nuclei
(Univ. Potsdam, 2008)Giacconi et al. (1962) discovered a diffuse cosmic X-ray background with rocket experiments when they searched for lunar X-ray emission. Later satellite missions found a spectral peak in the cosmic X-ray background at ~30 ... -
X-ray studies of ultraluminous infrared galaxies observed with XMM-Newton

Year‐round sub‐seasonal forecast skill for Atlantic–European weather regimes
; ; ; ; (Quarterly Journal of the Royal Meteorological Society, 2021-10-25)
Weather regime forecasts are a prominent use case of sub‐seasonal prediction in the midlatitudes. A systematic evaluation and understanding of year‐round sub‐seasonal regime forecast performance is still missing, however. ... -
Yield Function of the DOSimetry TELescope Count and Dose Rates Aboard the International Space Station
Caprotti, A. S.; Brüdern, M.;; ; (Space Weather, 2021-04-28)
The Earth is constantly hit by energetic particles originating from galactic sources. The flux of these particles is altered by the magnetized solar wind in the heliosphere and the Earth's magnetic field. For this reason, ... -
Zeeman-Doppler Imaging of active late-type stars
(Univ. Potsdam, 2009)Stellar magnetic fields, as a crucial component of star formation and evolution, evade direct observation at least with current and near future instruments. However investigating whether magnetic fields are generated by a ... -
Zonal Wave Number Diagnosis of Rossby Wave-Like Oscillations Using Paired Ground-Based Radars
; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2020)
Free traveling Rossby wave normal modes (RNMs) are often investigated through large-scale space-time spectral analyses, which therefore is subject to observational availability, especially in the mesosphere. Ground-based ... -
Zur Entstehung kleinräumiger, kohärenter Bodendrucksignaturen über der Norddeutschen Tiefebene
(Univ. Hannover, 2006)Meßkampagnen mit Mikrobarometermeßnetzen haben in der Vergangenheit gezeigt, daß sich in den Drucksignaturen nahezu permanent räumlich kohärente Strukturen (KST) abbilden. Ein Teil dieser KST wird durch Schwerewellen ... -
Zur Ermittlung geophysikalischer Massensignale mit Schwerefeldmissionen - eine Analyse des gegenwärtigen Standes am Beispiel der Antarktis
(Univ. Dresden, 2007)Die neuen Schwerefeld-Satellitenmissionen CHAMP (Challenging Minisatellite Payload), GRACE (Gravity Recovery and Climate Experiment) und GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) können wesentlich ... -
