Decadal Predictions of the Link Between European Hot‐Dry Compound Summers and North Atlantic Sea Surface Temperature

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract We assess MPI‐ESM 1.2‐LR decadal hindcasts (lead year 1–5) to evaluate the prediction of European compound hot and dry summers with help of North Atlantic sea surface temperature (SST). Using a 64‐member ensemble and detrended data, we isolate extremes driven by internal variability.

Identifying Energy Balance Drivers of Greenland Ice Sheet Surface Melt Using Causal Discovery

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Greenland Ice Sheet (GrIS) mass loss has accelerated in recent decades, primarily due to enhanced surface melt. Identifying the causal dependencies of surface melt remains challenging with conventional correlations. Using the PCMCI+ ${\text{PCMCI}}^{+}$ causal discovery algorithm applied to CESM2 large‐ensemble simulations and evaluated ...

Enhanced Interdecadal Variability in the WACE and Its Oceanic Drivers

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract As the Earth warms, the “warm Arctic–cold Eurasia” (WACE) has changed noticeably, with enhanced interdecadal variability as the Arctic heats up, particularly over the Barents–Kara Sea region. Before the early 1980s, when Arctic warming was relatively weak, WACE was mainly influenced by Pacific temperature patterns (the Pacific Decadal ...

Global Hotspots of Stalling Extratropical Cyclones

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Extratropical cyclones (ETCs) are primary drivers of extreme weather in the mid‐to‐high latitudes. We introduce a new classification of particularly impactful events—“stalling” ETCs—defined by slow movement combined with intense precipitation. Using cyclone tracking data, we find that stalling ETCs cluster systematically along the east coasts ...

Circumglobal Teleconnection and Early Summer Rainfall in the U.S. Intermountain West

, 2010
Physical processes responsible for the abnormally wet condition in the Central Intermountain West (CIW) of the United States in June 2009 were investigated. It was illustrated that persistent rainy conditions over the CIW during June 2009 were associated

Anthropogenic Aerosols Influence Tropical Pacific Sea Surface Temperature Gradient Trends

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The tropical Pacific is warming more in the west than the east. This observed strengthening of the tropical Pacific east‐to‐west Sea Surface Temperature (SST) gradient is poorly reproduced in climate models—a prominent model bias with far reaching global impacts.

Volcanic Forcing Amplifies Extreme Wet‐to‐Dry in Pre‐Flood South China Driven by Internal Variability

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Dry‐wet whiplash events profoundly impact society and the environment, yet their attribution remain poorly understood. This study reveals that the unprecedented interannual wet‐to‐dry transition (return period: 979.2 years) in South China's 1962–1963 pre‐flood season is co‐driven by internal variability and volcanic forcing.

Large‐Scale Moisture Circulation Index Related to Socioeconomic Drought and Its Subseasonal Forecast Skill in the Asian Monsoon Rainy Season

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Socioeconomic drought, which occurs when water demand exceeds available supply and often leads to water withdrawal restrictions, affects water resource management. However, the relationship between large‐scale moisture circulation and the occurrence of socioeconomic drought has not been well understood. In this study, we focused on the Yoshino

On the teleconnectivity of the “Arctic Oscillation”

Geophysical Research Letters, 2000
The term “Arctic Oscillation” (AO) has recently been introduced to describe the leading structure of SLP variability over the Northern Hemisphere. A key feature of the AO is its zonally symmetric appearance, with a primary center of action over the Arctic and opposing anomalies in midlatitudes.

Atmospheric Dust Transport to High‐Elevation Dronning Maud Land, Antarctica, Modulated by Cyclonic Circulation, the Pacific Decadal Oscillation, and Source Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract The dependence of aeolian dust transport on atmospheric circulation patterns allows dust preserved in Antarctic ice cores to serve as a proxy for past circulation variability. Here, we investigate dust transport to high‐elevation Dronning Maud Land (DML) in Antarctica through analysis of the 1300‐year‐old ISOL‐ICE ice core dust record together
