Rotational Flow Dominates Abrupt Seasonal Change in Zonally Asymmetric Tropical Meridional Circulation

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The seasonal evolution of tropical meridional circulation varies across regions and plays a key role in monsoon onset and rainfall migration, with important impacts on agriculture and disaster preparedness. Observations show that these transitions often occur abruptly within days.

Northern Hemisphere Warm Fronts Are Less Efficient at Precipitating Ice Than Their Southern Hemisphere Counterparts

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Using satellite observations, ice water path (IWP), liquid water path (LWP), and surface precipitation across warm frontal regions are examined in the Northern (NH) and Southern (SH) Hemispheres, accounting for the life stages and characteristics of extratropical cyclones (ETCs).

Interdecadal Increase in Spring‐To‐Summer Persistence of Central American Precipitation Anomalies

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Central American agriculture and ecosystems are acutely sensitive to rainfall that spans the spring‐summer growing window, yet most studies still evaluate each season in isolation. Here we demonstrate that, since the 2000s, Central American precipitation anomalies in spring have become more likely to persist into summer‐a shift that single ...

Differentiating Average and Extreme Extra‐Tropical Cyclones by Their Vertical Tilt and Potential Vorticity Structure

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This study compares the vertical tilt and potential vorticity (PV) $(PV)$ structure of average and extreme extra‐tropical cyclones (ETCs) in the Northern Hemisphere during the cold season (October–March) in ERA5 reanalysis. Vertical tilt is quantified using a novel two‐component (directional and lateral, aligned with and across cyclone motion)

Ice Multiplication Modulates the Medicane's Track and Thermodynamic Evolution

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Medicanes are high‐impact weather systems in the Mediterranean region, associated with floodings, severe damage and human casualties. While there has been continuous effort to understand the dynamic aspects of these systems, little is known about the underlying cloud‐scale processes, which cannot be resolved explicitly, consisting a notorious ...

Weakening of Regional Hadley Circulation Delays Indian Summer Monsoon Rainfall Onset

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The timing of the Indian Summer Monsoon Rainfall (ISMR) onset significantly influences agriculture, food security, livelihoods, and the Indian economy. While the drivers of climatological ISMR onset are well discussed, the causes of delayed ISMR onset remain unclear.
