Present and early star formation - a study on rotational and thermal properties
(Univ. Potsdam, 2006)We investigate the rotational and thermal properties of star-forming molecular clouds using hydrodynamic simulations. Stars form from molecular cloud cores by gravoturbulent fragmentation. Understanding the angular momentum ... -
Present‐Day Upper‐Mantle Architecture of the Alps: Insights From Data‐Driven Dynamic Modeling
; ; ; ; (Geophysical Research Letters, 2022-09-19)
The dynamics of the Alps and surrounding regions is still not completely understood, partly because of a non‐unique interpretation of its upper‐mantle architecture. In particular, it is unclear if interpreted slabs are ... -
Preserving the coupled atmosphere–ocean feedback in initializations of decadal climate predictions
; (Wiley Interdisciplinary Reviews: Climate Change, 2020)
On interannual to decadal time scales, memory in the Earth's climate system resides to a large extent in the slowly varying heat content of the ocean, which responds to fast atmospheric variability and in turn sets the ... -
Pressure‐Driven Poiseuille Flow Inherited From Mesozoic Mantle Circulation Led to the Eocene Separation of Australia and Antarctica
; ; (Journal of Geophysical Research: Solid Earth, 2021-04-27)
The separation between Australia and Antarctica occurred during the final stages of the break‐up of Pangea. Reconstructions of the rifting of the Australian plate away from Antarctica show fast spreading rates since ... -
Pre‐instrumental summer precipitation variability in northwestern Greece from a high‐elevation Pinus heldreichii network
; Konter, Oliver; ; Krusic, Paul J.; Büntgen, Ulf (International Journal of Climatology, 2021-01-10)
The spatiotemporal variability of precipitation is of vital importance to Mediterranean ecology and economy, but pre‐instrumental changes are not well understood. Here, we present a millennial‐length June–July precipitation ... -
Probabilistic Models Significantly Reduce Uncertainty in Hurricane Harvey Pluvial Flood Loss Estimates
; ; ; Müller, Meike; ; Doss‐Gollin, James; ; (Earth's Future, 2019-04-09)
Pluvial flood risk is mostly excluded in urban flood risk assessment. However, the risk of pluvial flooding is a growing challenge with a projected increase of extreme rainstorms compounding with an ongoing global urbanization. ... -
Probabilistic temperature forecasting with a heteroscedastic autoregressive ensemble postprocessing model
; (Quarterly Journal of the Royal Meteorological Society, 2019)
Weather prediction today is performed with numerical weather prediction (NWP) models. These are deterministic simulation models describing the dynamics of the atmosphere, and evolving the current conditions forward in time ... -
Probing quasar sight lines in three dimensions
(Univ. Potsdam, 2005)Strong damped Lyman alpha absorption (DLA) lines seen spectra of distant quasar are believed to arise when the sight line to the quasar goes trough the disc of a galaxy or a proto galaxy. Most of the neutral matter in the ... -
Process-Based Simulation of Aerosol-Cloud Interactions in a One-Dimensional Cirrus Model
(Journal of Geophysical Research: Atmospheres, 2020)
A new microphysical cirrus model to simulate ice crystal nucleation, depositional growth, and gravitational settling is described. The model tracks individual simulation ice particles in a vertical column of air and allows ... -
Process-oriented analysis of aircraft soot-cirrus interactions constrains the climate impact of aviation
; ; (Communications Earth & Environment, 2021-06-17)
Fully accounting for the climate impact of aviation requires a process-level understanding of the impact of aircraft soot particle emissions on the formation of ice clouds. Assessing this impact with the help of global ... -
Processes governing the amplification of ensemble spread in a medium-range forecast with large forecast uncertainty
(Quarterly Journal of the Royal Meteorological Society, 2019)This study provides a process-based perspective on the amplification of forecast uncertainty and forecast errors in ensemble forecasts. A case from the North Atlantic Waveguide and Downstream Impact Experiment that exhibits ... -
Processes of Stratification and Destratification During An Extreme River Discharge Event in the German Bight ROFI
; ; ; ; Kreus, Markus; ; ; ; (Journal of Geophysical Research: Oceans, 2020-08-15)
Processes of stratification and destratification in the German Bight region of fresh water influence (ROFI) are investigated following an extreme river discharge event in June 2013. For this purpose, a high‐resolution ... -
Prognose abbauinduzierter seismischer Ereignisse mittels eines markscheiderischen Gebirgsbewegungsmodells
(TU Bergakademie Freiberg, Fakultät Geowissenschaften, Geotechnik und Bergbau, Freiberg <Sachsen>, 2006)In der vorliegenden Arbeit werden Zusammenhänge zwischen bergbaulich bedingten Gebirgsbewegungen und induzierten seismischen Ereignissen dargestellt und für unterschiedliche Messfälle eine Prognose gerechnet. Ferner konnte ... -
Projected changes in synoptic circulations over Europe and their implications for summer precipitation: A CMIP6 perspective
; ; ; (International Journal of Climatology, 2023-02-20)
Abstract Projected changes in summer precipitation deficits partly depend on alterations in ...

Projected Impact of Increased Global Warming on Heat Stress and Exposed Population Over Africa
; ; ; ; ; ; (Earth's Future, 2023-01-11)
This study investigates the impact of increased global warming on heat stress changes and the potential number of people exposed to heat risks over Africa. For this purpose a heat index has been computed based on an ... -
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
