Martian Atmospheric Loss Through Foreshock Transient Events

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract At Mars, the MAVEN spacecraft has made observations of Hot Flow Anomalies (HFAs) in the foreshock. Due to the bow shock's proximity to the planet, it is theorized that HFAs contribute to atmospheric escape at Mars through the excavation of ionospheric ions.

Linking Hadley Cell Instability to Slow Equatorial Motions in Reanalysis and CMIP6 Models

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract A recent theory–originally proposed for tropical depression (TD)‐type waves–is extended to the Madden‐Julian Oscillation (MJO) and convectively‐coupled equatorial Rossby (ER) waves across the Indo‐Western Pacific region using reanalysis and Coupled Model Intercomparison Project Phase 6 (CMIP6) data. This framework posits that waves grow from a

Investigating the Periphery Region in Warm Cumulus Clouds

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Warm cumulus clouds are key components of Earth's weather and climate systems, yet mixing processes within them and their interaction with their environment remain a major source of uncertainty in climate predictions. Based on adiabatic fraction (AF), such clouds can be divided into three regions: the adiabatic core, the skin (the diluted ...

Early to Mid‐Holocene Cool Temperature‐Induced Drought in Asian Interior

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Hydroclimatic variations in mid‐latitude Asia during the early to mid‐Holocene and associated mechanisms remain disputed, hampering our understanding of atmospheric circulation controls on regional climatic changes. We report Holocene alkenone records from two Siberian lakes, documenting lake temperature and hydrological changes, and ...
