Variability of the precipitation over the Tianshan Mountains, Central Asia. Part I: Linear and nonlinear trends of the annual and seasonal precipitation
; ; (International Journal of Climatology, 2021-06-21)
The Tianshan Mountains, with their status as ‘water tower’, receive quantities of precipitation that are among the highest in Central Asia. There are considerable knowledge gaps regarding the understanding of spatial and ... -
Variation of Fault Creep Along the Overdue Istanbul‐Marmara Seismic Gap in NW Türkiye
; ; ; ; (Geophysical Research Letters, 2023-03-22)
Strain energy from tectonic loading can be partly released through aseismic creep. Earthquake repeaters, repeatedly activated brittle fault patches surrounded by creep, indicate steady‐state creep that affects the amount ... -
Verbesserung der Richtungsstabilisierung von inertial gesteuerten astronomischen Flugzeugteleskopen am Beispiel von SOFIA
(Univ. Berlin, 2006)Diese Arbeit beschreibt die Verbesserung der Richtungsstabilisierung des Flugzeugteleskops SOFIA. Das Ziel des Flugzeugteleskops SOFIA sind astronomische Beobachtungen im Infrarotbereich. Da der Wasserdampf der Erdatmosphäre ... -
Verbreitung und Eigenschaften von Massenverlagerungsgebieten an der Wellenkalk-Schichtstufe im Thüringer Becken unter besonderer Berücksichtigung geomorphologischer und klimatologischer Steuerungsfaktoren
(Univ. Halle, 2002)Die Wellenkalk-Schichtstufe im Thüringer ist allgemein als sehr massenverlagerungsanfällig bekannt. Über das großräumige Ausmaß der Massenbewegungen wußte man bislang jedoch nur sehr wenig. Es fehlten Informationen zu ... -
Verfahren der digitalen Photogrammetrie bei der Auswertung historischer Luftbilder zur Erfassung von Altlastverdachtsflächen
(Univ. Bochum, 2008)In dieser Arbeit werden Verfahren und Methoden entwickelt und angewendet, mit deren Hilfe historische Luftbilder für die Erfassung von Altlastverdachtsflächen photogrammetrisch ausgewertet werden können. Diese werden an ... -
Vertical Structure of the Arctic Spring Transition in the Middle Atmosphere
; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2021-05-13)
In the middle atmosphere, spring transition is the time period where the zonal circulation reverses from winter westerly to summer easterly which has a strong impact on the vertical wave propagation influencing the ionospheric ... -
Viscous flow of magmas from Unzen volcano, Japan - implication for magma mixing and ascent
(Univ. Hannover, 2006)Viscosity, magma, Unzen -
Water temperature control on CO2 flux and evaporation over a subtropical seagrass meadow revealed by atmospheric eddy covariance
; Lopes, Christian C.; ; Price, René M.; ; Fourqurean, James W. (Limnology and Oceanography, 2020-10-08)
Subtropical seagrass meadows play a major role in the coastal carbon cycle, but the nature of air–water CO2 exchanges over these ecosystems is still poorly understood. The complex physical forcing of air–water exchange in ... -
Water vapor in the tropical upper troposphere - on the influence of deep convection
(Univ. Köln, 2002)Wasserdampf ist eines der wichtigsten atmosphärischen Spurengase. Sein Einfluss auf das Klima, die Chemie und den Energiehaushalt ist bedeutend. Von besonderem Interesse ist dabei die Wasserdampfverteilung in der oberen ... -
Wavefield methods to analyze passive ocean bottom seismic data - application to the Tyrrhenian sea
(Univ. Hamburg, 2006)
In this study different full waveform techniques was developed for the investigation of seismic ocean bottom single station data. These techniques were applied to data obtained in a pilot ocean bottom experiment in the ... -
Waveguide heterodyne mixers at THz-frequencies - superconducting hot electron bolometers on 2-m63m [2-mym] Si3N4 membranes for GREAT and CONDOR
(Univ. Köln, 2007)Design and performance of waveguide mixers at 1.4 THz and 1.9 THz based on NbTiN phonon-cooled hot electron bolometers (HEB) fabricated on a 2 æm thick Si_3N_4 membrane. The membrane is bonded to a silicon frame in the ... -
Wavelet transform‐based seismic facies classification and modelling: application to a geothermal target horizon in the NE German Basin
; Norden, Ben; Ivanova, Alexandra; Stiller, Manfred; (Geophysical Prospecting, 2019-09-10)
At the geothermal test site near Groß Schönebeck (NE German Basin), a new 3D seismic reflection survey was conducted to study geothermal target layers at around 4 km depth and 150°C. We present a workflow for seismic facies ... -
Weather regimes and analogues downscaling of seasonal precipitation for the 21st century: A case study over Israel
; Kunin, Pavel; Alpert, Pinhas; Harpaz, Tzvi; ; (International Journal of Climatology, 2019)
Abstract Global climate models provide only partial information on local-scale phenomenon, such as precipitation, primarily due to their coarse resolution. In this study, statistical downscaling algorithms, based on both ... -
WeatherBench: A Benchmark Data Set for Data-Driven Weather Forecasting
; ; ; ; ; (Journal of Advances in Modeling Earth Systems, 2020)
Data-driven approaches, most prominently deep learning, have become powerful tools for prediction in many domains. A natural question to ask is whether data-driven methods could also be used to predict global weather ... -
