Characterizing Australian Solar Resource Variability and Solar Droughts With Himawari‐8/9

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Solar energy is central to decarbonization and national energy plans, yet its deployment is limited by gaps in understanding how solar irradiance varies in space and time. We present the first continent‐scale, sub‐daily analysis of solar resource variability using Himawari‐8/9 satellite data for Australia's renewable energy zones.

Implications of East Pacific La Niña Events for Southern African Climate

Atmosphere
Longitudinal shifts in the zonal dipole associated with the El Niño–Southern Oscillation (ENSO) in the tropical Pacific have implications for the summer climate of Southern Africa.

Changes in MJO Teleconnections in the Southeast U.S. Under Global Warming in the CESM2 Large Ensemble

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We examined projected changes in Madden–Julian Oscillation (MJO) teleconnections over North America using 90 ensemble members from the Community Earth System Model Version 2 Large Ensemble (CESM‐LENS2) under the SSP370 scenario. In the warmer climate, the classic PNA‐like teleconnection strengthens and shifts eastward, with large ensemble ...

IOD-driven seesaw mode of upper-ocean salinity variability in the central and eastern tropical Indian Ocean

Environmental Research Letters
Understanding the mechanisms behind interannual salinity variability in the tropical Indian Ocean (TIO) is crucial for interpreting its role in regional and global climates.

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

Journal 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.

Indian Ocean Dipole: Processes and impacts

, 2009
Equatorial Indian Ocean is warmer in the east, has a deeper thermocline and mixed layer, and supports a more convective atmosphere than in the west. During certain years, the eastern Indian Ocean becomes unusually cold, anomalous winds blow from east to west along the equator and southeastward off the coast of Sumatra, thermocline and mixed layer lift ...

Interbasin Analysis of the Poleward Expansion of Tropical Cyclone Potential Intensity

Journal 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.

Nonlinear country-heterogenous impact of the Indian Ocean Dipole on global economies

Nature Communications
A positive Indian Ocean Dipole features an anomalously high west-minus-east sea surface temperature gradient along the equatorial Indian Ocean, affecting global extreme weathers.

A Global Climatology of Large‐Scale Convergence Lines and Their Influence on Monsoon Variability in India, West Africa, and Australia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Low‐level (1,000–850 hPa), 6‐day time‐mean large‐scale convergence lines are identified objectively in the ERA5 reanalysis and are sorted into two classes according to whether the local specific humidity is high (high‐q) or low (low‐q). The high‐q convergence lines lie in the tropics, and in particular in the Intertropical Convergence Zone ...
