Geophysical Research LettersMars lacks an intrinsic dipolar magnetic field but possesses strong crustal magnetic fields scattered across its surface. There has been an ongoing debate about how these crustal fields influence the bow shock, the outermost plasma boundary of the ...

Geophysical Research Letters, 2020 Exploring relationships between different types of slow earthquakes is essential for determining their source properties and controlling parameters. Studies show that very low frequency earthquakes (VLFEs) and tremor are discrete events that necessitate ...

A Long‐Term View of Episodic Tremor and Slip in Cascadia
Geophysical Research Letters, 2020 Episodic Tremor and Slip, or ETS, is a well‐recognized phenomenon in the Cascadia subduction zone. Constraining the precise location of geodetically measured slip during ETS is important for clarifying the relationship between slip and tremor during ETS,

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz
Space WeatherThe most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines.

Geophysical Research Letters, 2020 Tropical cyclone maximum intensity is believed to result from a balance between the surface friction, which removes energy, and a temperature/moisture (enthalpy) difference between the sea surface and the air above it, which adds energy.

Geophysical Research LettersCyclones at polar latitudes of the Atlantic‐Arctic corridor exhibit different thermodynamic characteristics. Midlatitude‐origin cyclones, which make up about 14% of wintertime cyclones in the region, are generally warm and moist. The more numerous Arctic‐

Experimentally Derived Thresholds for Windblown Sand on Mars
Geophysical Research Letters, 2020 Aeolian sand transport frequently occurs on Mars despite wind speeds rarely exceeding predicted thresholds for motion. This dissonance is problematic for understanding aeolian processes and the resulting geomorphologic responses in contemporary and ...

Hysteresis of the Antarctic Ice Sheet With a Coupled Climate‐Ice‐Sheet Model
Geophysical Research LettersThe stability of the Antarctic ice sheet under different fixed CO2 levels and orbital configurations is explored using a coupled climate‐ice sheet model, starting from either a pre‐industrial ice sheet or an ice‐free, isostatically rebounded geometry ...

Empirically Estimated Electron Lifetimes in the Earth's Radiation Belts: Comparison With Theory
Geophysical Research Letters, 2020 We compute quasilinear diffusion rates due to pitch angle scattering by various mechanisms in the Earth's electron radiation belts. The calculated theoretical lifetimes are compared with observed decay rates, and we find excellent qualitative agreement ...

Snow Mass Recharge of the Greenland Ice Sheet Fueled by Intense Atmospheric River
Geophysical Research LettersAtmospheric rivers (ARs) have been linked with extreme rainfall and melt events across the Greenland ice sheet (GrIS), accelerating its mass loss. However, the impact of AR‐fueled snowfall has received less attention, partly due to limited empirical ...
