An Analysis of Hurricane Eyewall Ice Using a Novel Lagrangian Trajectory and Growth Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Ice crystals in tropical cyclones (TCs) remain infrequently observed and difficult to model using Eulerian microphysics parameterizations. To better understand TC eyewall ice crystal processes, the Ice Crystal Trajectory Growth (ICTG) model, previously applied to an idealized squall line, was used to simulate Lagrangian ice crystal ...

Exploring Global Patterns of Trace Metal Limitation as a Regulator of the Distribution of Dominant Marine Phytoplankton Groups

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
By synthesizing decades of culture data with modern oceanographic datasets, we modelled trace metal limitation of phytoplankton. Our analysis reaffirms the critical role of iron but additionally highlights a significant, growing impact of zinc on the biological pump in future oceans.

Satellite motion for all inclinations around an oblate planet [PDF]

Symposium - International Astronomical Union, 1966
A uniformly valid solution for the motion of a satellite around an oblate planet is presented. The Two-Variable Expansion Procedure was applied to obtain a solution valid for all inclinations including the critical. This solution is correct to order ε, where ε is a small parameter proportional to the oblateness parameterJ2. The reciprocal of the radius

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Temporal Variability of Saturn's H2 Dayglow and Northern Aurora Observed by Hisaki and Cassini

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Ultraviolet (UV) emissions from molecular hydrogen in Saturn's atmosphere consist of bright auroral emission over the poles and disk‐wide airglow. The dayside disk emits substantial intensities (dayglow) previously detected by various instruments.

3D Variations in Viscosity Reconcile the Strength of the Lower Mantle Inferred From Glacial Isostatic Adjustment and Mantle Convection

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A widely accepted global model of glacial isostatic adjustment (GIA) is based on ICE‐6G ice loading and 1D‐viscosity model VM5a, a viscosity profile which remains at odds with mantle convection constraints such as from geoid modeling. We explore 3D‐viscosity variations in models of GIA and show that a model with lateral viscosity variations ...

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.
