Sources of Subseasonal Predictability for Precipitation in South America Based on Model Experiments

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract This study investigates the sources of predictability underlying subseasonal precipitation skill over South America in existing subseasonal prediction systems. Using subseasonal re‐forecasts from the NCAR‐CESM2 model, we demonstrate that significant skill persists even when interannual variability is removed.

The Moist Static Energy Budget of Australian Summer Monsoon Bursts in Climate Models: Insights From Present and Warming Climate Scenarios

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract This study investigates the complex dynamics of burst evolution in the Australian summer monsoon under present‐day and warmer climate conditions. Using reanalysis data, historical atmosphere‐only simulations (AMIP), and simulations with uniformly increased sea surface temperatures (+4K; AMIP+4K), we examine how seasonal‐mean precipitation and ...

Interbasin Analysis of the Poleward Expansion of Tropical Cyclone Potential Intensity

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Favorable thermodynamic environments for tropical cyclone (TCs), as measured by potential intensity (PI), expand to higher latitudes in a warming climate, in both observations and future simulations. However, this expansion rate has yet to be compared systematically between hemispheres and across basins.

Weather and Climate Extremes: Simplex, Dynamical Systems and Hull Clustering

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract A novel method is developed and applied to identify high‐dimensional weather and climate extremes located on the envelope of the data set within its state space. The method is based on formulating and integrating dynamical systems whose attractive set, that is, stable fixed points, is constituted of extreme states residing on the convex hull ...
