The Spectrum of Slip Behaviors of a Granular Fault Gouge Analogue Governed by Rate and State Friction
(
- Geochemistry, Geophysics, Geosystems
, 2021-12-15)
Currently, it is unknown how seismic and aseismic slip influences the recurrence and magnitude of earthquakes. Modern seismic hazard assessment is therefore based on statistics combined with numerical simulations of fault ...
Consequences of regularizing the Sawyer–Eliassen equation in balance models for tropical cyclone behaviour
(
- Quarterly Journal of the Royal Meteorological Society
, 2019)
The consequences of regularizing the Sawyer–Eliassen equation to calculate the stream function for the axisymmetric secondary circulation of a tropical cyclone are explored. Regularization is an ad hoc procedure in which ...
The seismological signature of cyclonic storms through the ears of a sensor array
(2021)
Under certain conditions, ocean surface gravity waves (SGW) interact with the seafloor underneath to trigger
relatively faint but measurable seismic waves known as ocean microseisms. Cyclonic storms (e.g.
hurricanes, ...
From Bright Windows to Dark Spots: Snow Cover Controls Melt Pond Optical Properties During Refreezing
(
- Geophysical Research Letters
, 2021-12-02)
Melt ponds have a strong impact on the Arctic surface energy balance and the ice‐associated ecosystem because they transmit more solar radiation compared to bare ice. In the existing literature, melt ponds are considered ...
Simulating Linear Kinematic Features in Viscous‐Plastic Sea Ice Models on Quadrilateral and Triangular Grids With Different Variable Staggering
(
- Journal of Advances in Modeling Earth Systems
, 2021-10-28)
Observations in polar regions show that sea ice deformations are often narrow linear features. These long bands of deformations are referred to as Linear Kinematic Features (LKFs). Viscous‐plastic sea ice models have the ...
Ionospheric Corrections for Satellite Altimetry ‐ Impact on Global Mean Sea Level Trends
(
- Earth and Space Science
, 2022-04-25)
Atmospheric delay corrections for satellite altimetry measurements are essential for deriving highly accurate sea surface heights and reliable global mean sea level (GMSL) trend estimates. A commonly used method to correct ...
Assessment of the Precision of Spectral Model Turbulence Analysis Techniques Using Direct Numerical Simulation Data
(
- Journal of Geophysical Research: Atmospheres
, 2022-02-17)
The spectral model turbulence analysis technique is widely used to derive kinetic energy dissipation rates of turbulent structures (ɛ) from different in situ measurements in the Earth's atmosphere. The essence of this ...
Analytical Solutions for Gravity Changes Caused by Triaxial Volumetric Sources
(
- Geophysical Research Letters
, 2022-04-18)
Volcanic crises are often associated with magmatic intrusions or the pressurization of magma chambers of various shapes. These volumetric sources deform the country rocks, changing their density, and cause surface uplift. ...
From the Top of Martian Olympus to Deep Craters and Beneath: Mars Radiation Environment Under Different Atmospheric and Regolith Depths
(
- Journal of Geophysical Research: Planets
, 2022-02-27)
In preparation for future human habitats on Mars, it is important to understand the Martian radiation environment. Mars does not have an intrinsic magnetic field and Galactic cosmic ray (GCR) particles may directly propagate ...
Rupture Heterogeneity and Directivity Effects in Back‐Projection Analysis
(
- Journal of Geophysical Research: Solid Earth
, 2022-03-03)
The back projection method is a tremendously powerful technique for investigating the time dependent earthquake source, but its physical interpretation is elusive. We investigate how earthquake rupture heterogeneity and ...
