Predicting Geothermal Heat Flow in Antarctica With a Machine Learning Approach
; (Journal of Geophysical Research: Solid Earth, 2021-06-10)
We present a machine learning approach to statistically derive geothermal heat flow (GHF) for Antarctica. The adopted approach estimates GHF from multiple geophysical and geological data sets, assuming that GHF is substantially ... -
Predicting Imminence of Analog Megathrust Earthquakes With Machine Learning: Implications for Monitoring Subduction Zones
; ; ; ; ; (Geophysical Research Letters, 2020-03-31)
Subduction zones are monitored using space geodesy with increasing resolution, with the aim of better capturing the deformation accompanying the seismic cycle. Here, we investigate data characteristics that maximize the ... -
Predictions of planets for 586 exosystems and a method for predicting planets in multi-planetary exosystems
(2019)We have applied a model of planetary system formation in the field of a standing sound wave (the ‘SSW-Model’) to the prediction of planets in 586 multi-planetary exosystems (384 biplanetary, 127 tri-planetary and 75 ... -
Predictions of the geomagnetic secular variation based on the ensemble sequential assimilation of geomagnetic field models by dynamo simulations
(Earth, Planets and Space, 2020-10-22)The IGRF offers an important incentive for testing algorithms predicting the Earth’s magnetic field changes, known as secular variation (SV), in a 5-year range. Here, we present a SV candidate model for the 13th IGRF that ... -
Prehistoric chamber tombs or geological pitfall? A multimethod case study from Ancient Aigeira with a focus on seismic full‐waveform inversion
; ; ; ; (Archaeological Prospection, 2021-07-16)
We show an extensive multimethod geophysical study of focusing on some enigmatic subsurface structures found at Ancient Aigeira (N Peloponnes, Greece) that could be interpreted either as prehistoric chamber tombs or complex ... -
Preliminary Statistical Comparisons of Spin‐Averaged Electron Data From Arase and Van Allen Probes Instruments
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2021-07-06)
Following the end of the Van Allen Probes mission, the Arase satellite offers a unique opportunity to continue in‐situ radiation belt and ring current particle measurements into the next solar cycle. In this study we compare ... -
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 ... -
