The South Pole‐Aitken Basin: Constraints on Impact Excavation, Melt, and Ejecta Citron, RI; Smith, DE; Stewart, ST; Hood, LL; Zuber, MT The formation and evolution of the South Pole‐Aitken (SPA) basin is critical to relating large impact basin formation and modification to lunar geophysical evolution. Most prior models of the SPA impact were conducted in 2D, making it difficult to compare model o…

The Non-Union Complaint System at MIT: An Upward-Feedback, Mediation Model Rowe, Mary P. Many corporations, universities, and other institutions have developed explicit, non-union complaint systems. The non-union complaint system at MIT is similar to those of several hundred other high-technology, white collar, and research oriented employers. The similarity is perhaps strongest with respect to w…

ENSO and West Pacific Seasonality Driven by the South Asian Monsoon Tuckman, PJ; Smyth, Jane E; Li, Jingyuan; Lutsko, Nicholas J; Marshall, John The equatorial Pacific exhibits a clear seasonal cycle, with West Pacific SSTs being highest during boreal autumn and El Niño/Southern Oscillation (ENSO) events tending to peak during boreal winter. In this work, we use the concept of a monsoonal mode an…

Vegetation‐Generated Turbulence Does Not Impact the Erosion of Natural Cohesive Sediment Deitrick, Autumn R; Ralston, David K; Esposito, Christopher R; Baustian, Melissa M; Burgos, Maricel Beltrán; Courtois, Andrew J; Nepf, Heidi Previous studies have demonstrated that vegetation‐generated turbulence can enhance erosion rate and reduce the velocity threshold for erosion of non‐cohesive sediment. …

Plant Morphology Impacts Bedload Sediment Transport Liu, Chao; Shan, Yuqi; He, Li; Li, Fujian; Liu, Xingnian; Nepf, Heidi Bedload sediment transport plays an important role in the evolution of rivers, marshes and deltas. In these aquatic environments, vegetation is widespread, and plant species have unique morphology. However, the impact of real plant morphology on flow and sediment transport has…

Contrasting Chlorine Chemistry on Volcanic and Wildfire Aerosols in the Southern Mid‐Latitude Lower Stratosphere Wang, Peidong; Solomon, Susan Volcanic eruptions and wildfires can impact stratospheric chemistry. We apply tracer‐tracer correlations to satellite data from Atmospheric Chemistry Experiment—Fourier Transform Spectrometer and the Halogen Occultation Experiment at 68 hPa to consistently…

Diurnal Vegetation Moisture Cycle in the Amazon and Response to Water Stress Asgarimehr, Milad; Entekhabi, Dara; Camps, Adriano Water stress in the Amazon is exacerbated by rising temperatures and reduced moisture levels. However, understanding forest responses to increased aridity is hindered by limited in situ water potential observations in the Amazon. Remote sensing of water content has emerg…

Local and General Patterns of Terrestrial Water‐Carbon Coupling Short Gianotti, Daniel J; Entekhabi, Dara Terrestrial carbon uptake and water availability have coupled feedbacks; specifically water uptake for plant growth and soil drying via transpiration. While we might expect this coupling over time at arid sites, climatic water availability also widely covaries geographically with biomass vari…

Dust Source Areas and Their Plume Extent Derived From Satellite Data Fields AlNasser, Faisal; Chehbouni, Abdelghani; Entekhabi, Dara In this study, prominent dust source areas are identified along with their plume extent using high temporal frequency satellite observations. Hourly dust plume observations of the Dust Belt from geostationary‐orbit satellites are analyzed for the 2017‐12–2022‐11 per…

The Transition to Double‐Celled Circulations in Mock‐Walker Simulations Lutsko, Nicholas J; Cronin, Timothy W Mock‐Walker simulations have the potential to play a key role in a tropical model hierarchy, bridging small‐scale Radiative‐Convective Equilibrium simulations and global models of tropical circulations. We demonstrate that mock‐Walker simulations transition from single‐ to double‐celled o…

Reply to Comment by Poppema and Wüthrich on “Momentum and Energy Predict the Backwater Rise Generated by a Large Wood Jam” Follett, Elizabeth; Schalko, Isabella; Nepf, Heidi Follett et al. (2020a, https://doi.org/10.1029/2020gl089346) developed an analytical model to predict backwater rise by log jams, using the size and packing density of logs and the jam length, as well as river slope and bed r…

Generalized Statistics on Lattices Kobayashi, Ryohei; Li, Yuyang; Xue, Hanyu; Hsin, Po-Shen; Chen, Yu-An The statistics of particles and extended excitations, such as loops and membranes, are fundamental to modern condensed matter physics, high-energy physics, and quantum information science, yet a comprehensive lattice-level framework for computing them remains elusive. In this work, we develop …

Stratospheric Chlorine Processing After the Unprecedented Hunga Tonga Eruption Zhang, Jun; Wang, Peidong; Kinnison, Douglas; Solomon, Susan; Guan, Jian; Stone, Kane; Zhu, Yunqian Following the Hunga Tonga–Hunga Ha'apai (HTHH) eruption in January 2022, significant reductions in stratospheric hydrochloric acid (HCl) were observed in the Southern Hemisphere mid‐latitudes during the latter half of 20…

Spatiotemporal Facility‐Level Patterns of Summer Heat Exposure, Vulnerability, and Risk in United States Prison Landscapes Ovienmhada, Ufuoma; Hines, Mia; Krisch, Michael; Diongue, Ahmed T; Minchew, Brent; Wood, Danielle R Heat is associated with increased risk of morbidity and mortality. People who are incarcerated are especially vulnerable to heat exposure due to demographic characteristics and…

Insights Into Changing Interglacial Conditions in Subarctic Canada From MIS 11 Through MIS 5e From Seasonally Resolved Speleothem Records Batchelor, Cameron J; McGee, David; Shakun, Jeremy D; Woodhead, Jon; Jost, Adam B; Arnold, Sarah; Horne, Greg; Kinsley, Christopher W; Freudenburg‐Puricelli, Markey High‐resolution records from past interglacial climates help constrain future responses to globa…

Symmetry-based efficient simulation of higher-order coherences in quantum many-body superradiance Holzinger, Raphael; Rubies-Bigorda, Oriol; Yelin, Susanne F.; Ritsch, Helmut We propose an efficient method to numerically simulate the superradiant emission dynamics of large numbers of quantum emitters in ordered arrays in the presence of long-range dipole-dipole interactions mediated by the vacuum…

Dynamical generation and transfer of nonclassical states in strongly interacting light-matter systems in cavities Tutunnikov, Ilia; Rokaj, Vasil; Cao, Jianshu; Sadeghpour, HR We propose leveraging strong and ultrastrong light-matter coupling to efficiently generate and exchange nonclassical light and quantum matter states. Two initial conditions are considered: (a) a displaced quadrature-squeezed…

While quantum transport …

Spatially Resolved Temperature Response Functions to CO2 Emissions Freese, Lyssa M; Giani, Paolo; Fiore, Arlene M; Selin, Noelle E Carbon dioxide (CO2) emissions affect local temperature; quantifying that local response is important for learning about the earth system, the impacts of mitigation, and adaptation needs. We assume the climate system can be represented as a time-dependent linear syste…
