The C‐Shaped Landmass: A Key Driver of Monsoon Formation

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Monsoon dynamics research has largely focused on idealized rectangular continents, primarily in the Northern Hemisphere mid‐latitudes. To investigate the broader impact of landmass configuration on monsoon formation and variability, we conducted extensive sensitivity experiments.

Effects of Wind and Isopycnal Mixing on Southern Ocean Surface Buoyancy Flux and Antarctic Bottom Water Formation

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract In coarse resolution ocean models, eddy diffusive effects are parameterized using an isopycnal mixing coefficient, which controls mixing strength along isopycnals. Recent high‐resolution simulations show that increasing the wind stress over the Southern Ocean leads to increased local isopycnal mixing.

Mercury's Tidal Love Number h2 ${h}_{2}$ From Co‐Registration of MLA Profiles

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Due to its eccentric orbit, Mercury experiences a varying gravitational pull from the Sun along its orbit, leading to periodic surface tidal deformation. The previous measurement of Mercury's tidal h2 ${h}_{2}$ by Bertone et al. (2021, https://doi.org/10.1029/2020je006683) is based on minimizing height differences at cross‐overs of the Mercury

Effects of Near‐Fault Sedimentary Rocks and Damage on the 2019 Ridgecrest, CA Earthquake: A Rupture Impediment or a Ground Motion Booster?

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Observations of the 2019 magnitude 7.1 Ridgecrest, California, earthquake indicate a relatively slow rupture (∼ ${\sim} $2 km/s). The fault is surrounded by sedimentary rocks and low‐velocity damage zones, which can amplify ground motions but also slow down rupture.

What Causes the Hemispheric Difference in the Asymmetry of the Temperature Annual Cycle?

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Previous studies have noted the asymmetry in the annual cycle of zonal mean surface air temperature, defined as the difference in the lengths of warming and cooling periods. Pronounced north‐south hemispheric differences in this asymmetry, by up to 40 days, were attributed to the eccentricity of Earth's orbit.
