A Decentralized Approach for Modeling Organized Convection Based on Thermal Populations on Microgrids
(Journal of Advances in Modeling Earth Systems, 2022-10-26)In this study, a spectral model for convective transport is coupled to a thermal population model on a two‐dimensional horizontal “microgrid,” covering the typical gridbox size of general circulation models. The goal is ... -
Minimal Recipes for Global Cloudiness
(Geophysical Research Letters, 2022-10-26)Clouds are primary modulators of Earth's energy balance. It is thus important to understand the links connecting variabilities in cloudiness to variabilities in other state variables of the climate system, and also describe ... -
Combination Strategy for the Geocentric Realization of Regional Epoch Reference Frames
(Journal of Geophysical Research: Solid Earth, 2022-10-25)For high‐resolution regional geodetic applications, the International Terrestrial Reference Frame (ITRF) is complemented by regional densifications. These are realized either as multi‐year solutions related to a tectonic ... -
The Role of Zooplankton Grazing and Nutrient Recycling for Global Ocean Biogeochemistry and Phytoplankton Phenology
(Journal of Geophysical Research: Biogeosciences, 2022-10-25)Zooplankton plays a notable role in ocean biogeochemical cycles. However, it is often simulated as one generic group and top closure term in ocean biogeochemical models. This study presents the description of three zooplankton ... -
Combining Commercial Microwave Link and Rain Gauge Observations to Estimate Countrywide Precipitation: A Stochastic Reconstruction and Pattern Analysis Approach
(Water Resources Research, 2022-10-24)Accurate spatiotemporal precipitation quantification is a crucial prerequisite for hydrological analyses. The optimal reconstruction of the spatial distribution, that is, the rainfall patterns, is particularly challenging. ... -
Middle Miocene Climate and Stable Oxygen Isotopes in Europe Based on Numerical Modeling
(Paleoceanography and Paleoclimatology, 2022-10-24)The Middle Miocene (15.99–11.65 Ma) of Europe witnessed major climatic, environmental, and vegetational change, yet we are lacking detailed reconstructions of Middle Miocene temperature and precipitation patterns over ... -
Chemical Geodynamics Insights From a Machine Learning Approach
(Geochemistry, Geophysics, Geosystems, 2022-10-19)The radiogenic isotope heterogeneity of oceanic basalts is often assessed using 2D isotope ratio diagrams. But because the underlying data are at least six dimensional (87Sr/86Sr, 143Nd/144Nd, 176Hf/177Hf, and 208,207,20 ... -
On the Ridging of the South Atlantic Anticyclone Over South Africa: The Impact of Rossby Wave Breaking and of Climate Change
(Geophysical Research Letters, 2022-10-19)Ridging South Atlantic Anticyclones contribute an important amount of precipitation over South Africa. Here, we use a global coupled climate model and the ERA5 reanalysis to separate for the first time ridging highs (RHs) ... -
Leveraging Governance Performance to Enhance Climate Resilience
(Earth's Future, 2022-10-17)Enhancing the resilience of complex social‐ecological systems (SES) to climate change requires transformative changes. Yet, there are knowledge gaps on how best to achieve transformation. In this study, we present an ... -
A Seismic Approach to Flood Detection and Characterization in Upland Catchments
(Geophysical Research Letters, 2022-10-17)About 10% of Europe's surface area is prone to rapid flooding of rivers confined in valleys. The devastating potential of such floods is exacerbated by the deficits of existing gauging networks, including low station ... -
Young magmatism and Si‐rich melts on Mars as documented in the enriched gabbroic shergottite NWA 6963
(Meteoritics & Planetary Science, 2022-10-17)Enriched shergottites contain interstitial Si‐rich mesostasis; however, it is unclear whether such mesostasis is formed by impact or magmatic processes. We use laser ablation multicollector inductively coupled plasma mass ... -
Spatio‐Temporal Level Variations of the Martian Seasonal North Polar Cap From Co‐Registration of MOLA Profiles
(Journal of Geophysical Research: Planets, 2022-10-14)The seasonal deposition and sublimation of CO2 constitute a major element in Martian volatile cycles. We reprocess the Mars Orbiter Laser Altimeter (MOLA) data and apply co‐registration procedures to obtain spatio‐temporal ... -
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. ... -
Early Eocene magnetostratigraphy and tectonic evolution of the Xining Basin, NE Tibet
(Basin Research, 2022-10-12)The Cenozoic strata of the Xining Basin, NE Tibet, have provided crucial records for understanding the tectonic and palaeo‐environmental evolution of the region. Yet, the age of the lower part of the sedimentary stratigraphy ... -
Spatial and temporal dynamics of aufeis in the Tso Moriri basin, eastern Ladakh, India
(Permafrost and Periglacial Processes, 2022-10-12)Aufeis is a common phenomenon in cold regions of the Northern Hemisphere that develops during winter by successive water overflow and freezing on ice‐covered surfaces. Most studies on aufeis occurrence focus on regions in ... -
Hidden Potential in Predicting Wintertime Temperature Anomalies in the Northern Hemisphere
(Geophysical Research Letters, 2022-10-11)Variability of the North Atlantic Oscillation (NAO) drives wintertime temperature anomalies in the Northern Hemisphere. Dynamical seasonal prediction systems can skilfully predict the winter NAO. However, prediction of the ... -
Stratus over rolling terrain: Large‐eddy simulation reference and sensitivity to grid spacing and numerics
(Quarterly Journal of the Royal Meteorological Society, 2022-10-11)The formation of low stratus cloud over idealized hills is investigated using numerical model simulations. The main driver for the cloud formation is radiative cooling due to outgoing longwave radiation. Despite a purely ... -
Drought Conditions Enhance Groundwater Table Fluctuations Caused by Hydropower Plant Management
(Water Resources Research, 2022-10-10)Management of hydropower plants strongly influences streamflow dynamics and hence the interaction between surface water and groundwater. As dam operations cause variations in river stages, these can result in changes in ... -
