Compound North American Cold and European Wind Extremes in ERA5 and CMIP6 Historical and Future Simulations. Part 2: Dynamical Pathways

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Wintertime North American cold spells often co‐occur with European wind extremes, forming so‐called pan‐Atlantic extremes. In Part 1 of this paper, we identified regionally varying relationships between the two sets of extremes in ERA5 reanalysis data.

Stratosphere‐Troposphere Exchange of Ozone and CO Over the North Pacific: Roles of Different Types of Rossby Wave Breaking With Multiple Chemical‐Reanalysis Perspectives

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract In this study, we investigate the characteristics of stratosphere‐troposphere exchange (STE) of ozone and carbon monoxide (CO) over the North Pacific on the 350 K isentropic surface during 2005–2021 using two chemical reanalyses (Copernicus Atmosphere Monitoring Service and TCR‐2).

Opposing Trends in Wintertime Convective Initiation Environments of East China Driven by Anthropogenic Aerosols and Greenhouse Gases

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Winter convection can trigger severe disasters due to low temperature, yet the drivers and mechanisms of regional long‐term trends in winter convective initiation remain unclear. Using homogenized radiosonde data, we reveal the spatially divergent trends in wintertime atmospheric unstable conditions, with a significant decrease in the northern

Asian Precipitation Changes in the Past Millennium: Projection of Volcanic Forcing Onto Internal Mode

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Asian precipitation changes over multiple time scales have been extensively studied, yet the relative roles of external forcing and internal variability in shaping the large‐scale Asian precipitation pattern over the past millennium remain underexplored. Here, we demonstrate that the tripolar pattern of decadal precipitation variability across

Upper Mantle Heterogeneity and Weak Subduction Boundaries Control Crustal Stress in the Korean Peninsula

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Most earthquakes occur at plate boundaries, but some also strike within stable continental interiors. Although dominant causes of such intraplate earthquakes remain elusive, a prevailing hypothesis attributes intraplate stress and seismicity to variations in lithospheric thickness.

Decadal Stability of Multi‐Scale Core‐Mantle Boundary in Core‐Reflections of Repeating Earthquakes

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Temporal changes near the core‐mantle boundary (CMB) would trigger insights into ongoing thermal and chemical interactions between the Earth's core and mantle. Here, we search for multidecadal temporal changes in the CMB topography and heterogeneity using waveform similarity analysis of core‐reflected phases (PcP, ScP, and ScS) from global ...

Attribution of Interdecadal Changes in the Spatial Structure of the Spring AO

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The Arctic Oscillation (AO) is one of the key atmospheric circulation modes in the mid‐to‐high latitudes of the Northern Hemisphere. The spatial structure of the spring AO exhibits pronounced interdecadal variation, primarily characterized by a shift of the midlatitude circulation center from the North Pacific Center (NPC) to the North ...

Holocene Hydroclimatic Variations Over Western and Central Asia as Inferred From Speleothem Isotope Evidence

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Recent studies have found a dipole pattern of hydroclimate variation in western Asia (WA) and arid central Asia (ACA) during the Holocene. However, speleothem δ18O evidence shows some inconsistencies with other lines of evidence, especially concerning the timing of peak wetness in WA and precipitation trends in ACA.

Synchronisation of Extreme Precipitation and Sea Surface Temperature Events in the Northern Hemisphere: A Complex Network Approach

International Journal of Climatology, Volume 46, Issue 3, 15 March 2026.
Using complex network theory and event synchronisation, we find distinct spatiotemporal structures of extreme precipitation and sea surface temperature events across the Northern Hemisphere. Our results show strong local and long‐range connectivity in terrestrial extremes, driven by atmospheric dynamics, contrasting with more localised marine extremes ...
