Projecting Stratocumulus Transitions on the Albedo—Cloud Fraction Relationship Reveals Linearity of Albedo to Droplet Concentrations
(Geophysical Research Letters, 2022-10-13)Satellite images show solid marine stratocumulus cloud decks (Sc) that break up over the remote oceans. The Sc breakup is initiated by precipitation and is accompanied by a strong reduction in the cloud radiative effect. ... -
Properties of quasistellar objects and their progenitors in the radio and mm wavelength regimes in the context of ULIRG-to-QSO evolution
(Univ. Köln, 2010)The thesis at hand presents the results of a study of galaxies with active galactic nuclei (AGN) carried out in the radio and mm wavelength regimes at low and high angular resolutions. The studied objects cover a broad ... -
Properties of Turbulent Alfvénic Fluctuations and Wave‐Particle Interaction Associated With Io's Footprint Tail
(Journal of Geophysical Research: Space Physics, 2022-12-09)We investigate the small‐scale magnetic field fluctuations and their associated turbulent nature in the Io flux tube (IFT) connected to Io's footprint tail (IFPT). Our study is based on the recent magnetic field measurements ... -
Properties of turbulent star-forming clusters - models versus observations
(Univ. Potsdam, 2006)Sterne entstehen im Inneren von turbulenten Molekülwolken, die unter dem Einfluss ihrer eigenen Gravitation fragmentieren und kollabieren. So entsteht ein Sternhaufen aus hundert oder mehr Objekten. Der Sternentstehungsprozess ... -
Quantifying Convective Aggregation Using the Tropical Moist Margin's Length
(Journal of Advances in Modeling Earth Systems, 2020)On small scales, the tropical atmosphere tends to be either moist or very dry. This defines two states that, on large scales, are separated by a sharp margin, well identified by the antimode of the bimodal tropical column ... -
Quantifying Progress Across Different CMIP Phases With the ESMValTool
(Journal of Geophysical Research: Atmospheres, 2020-10-27)More than 40 model groups worldwide are participating in the Coupled Model Intercomparison Project Phase 6 (CMIP6), providing a new and rich source of information to better understand past, present, and future climate ... -
Quantifying the Central European Droughts in 2018 and 2019 With GRACE Follow-On
(Geophysical Research Letters, 2020)The GRACE-FO satellites launched in May 2018 are able to quantify the water mass deficit in Central Europe during the two consecutive summer droughts of 2018 and 2019. Relative to the long-term climatology, the water mass ... -
Quantifying the Effects of EMIC Wave Scattering and Magnetopause Shadowing in the Outer Electron Radiation Belt by Means of Data Assimilation
(Journal of Geophysical Research: Space Physics, 2020)In this study we investigate two distinct loss mechanisms responsible for the rapid dropouts of radiation belt electrons by assimilating data from Van Allen Probes A and B and Geostationary Operational Environmental ... -

Quasi‐10‐Day Wave and Semidiurnal Tide Nonlinear Interactions During the Southern Hemispheric SSW 2019 Observed in the Northern Hemispheric Mesosphere
(Geophysical Research Letters, 2020-11-26)Mesospheric winds from three longitudinal sectors at 65°N and 54°N latitude are combined to diagnose the zonal wave numbers (m) of spectral wave signatures during the Southern Hemisphere sudden stratospheric warming (SSW) ... -
Quasi‐4‐Day Wave: Atmospheric Manifestation of the First Symmetric Rossby Normal Mode of Zonal Wavenumber 2
(Journal of Geophysical Research: Atmospheres, 2021-07-07)This paper describes global characteristics of the westward‐propagating planetary wave with a period of ∼4 days and zonal wavenumber 2, here referred to as quasi‐4‐day wave (Q4DW), which is considered to be a manifestation ... -
Quaternary tectonics and seismic stratigraphy of the western Black Sea shelf
(Univ. Hamburg, 2009)Interpretation of high and very high resolution reflection seismic data from the western Black Sea shelf yielded a seismic stratigraphic model of the Late Quaternary deposits on the southwestern Black Sea shelf. This model ... -
Radiative transfer in the exosphere of Saturn's moon Titan
(Univ. Berlin, 2009)This work focuses on the distribution of atomic hydrogen in the exosphere of Saturns̉ moon Titan. This work is based on measurements performed by the Hydrogen Deuterium Absorption Cell (HDAC) aboard the Cassini spacecraft, ... -
