Synchronized Heat Extremes in the Northern Hemisphere Based on a Complex Network

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Heat extremes occurring synchronously in multiple regions often result in more severe impacts than isolated heat events. Here we analyze observational and reanalysis data to objectively detect and examine the synchronization of heat extremes in the Northern Hemisphere and identify the regions that have remote linkages, particularly in western ...

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).

Convective Organization in African Easterly Waves Observed During the NAMMA and CPEX‐CV Field Campaigns

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Fundamental questions remain about where and when convection will occur within African easterly waves. In this study, we aim to better understand the dynamical processes that govern moist convective organization at the meso‐alpha scale in tropical easterly waves using NASA airborne field campaigns and satellite observations.

Extremes in Southern Hemispheric Zonal Wave‐3 and Their Impact on Antarctic Sea‐Ice Thickness

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Zonal Wave‐3 (ZW3) is a key zonally asymmetric component of the large‐scale extratropical atmospheric circulation, facilitating mass and energy exchanges between middle and high latitudes in the Southern Hemisphere. Despite the crucial role of sea‐ice thickness (SIT) in modulating sea‐ice volume and climate feedbacks, its response to ZW3 ...

Overturning Circulation of the North Atlantic Subtropical Gyre Computed in Density Coordinates at 26°N

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The RAPID‐MOCHA‐WBTS array in the subtropical gyre of the North Atlantic has measured the Atlantic Meridional Overturning Circulation (AMOC) and the overturning streamfunction in depth coordinates since 2004. Here we show that the overturning streamfunction in density coordinates can be estimated by combining data from the RAPID‐MOCHA‐WBTS ...

California Temperature Since 1520 CE Shows Interactions in Extremes of Heat, Drought, and Fire

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Summer maximum temperatures (Tmax ${T}_{\text{max}}$) in the Sierra Nevada have risen rapidly since the turn of the 20th century, especially above 1,500 m where trends in the south exceed 3°C century−1. To place this warming into context, we developed a 504‐year reconstruction of growing‐season (April–September) Tmax ${T}_{\text{max}}$ (1520 ...

On the Coherent and Incoherent Characteristics of Semidiurnal Internal Tides Near the Luzon Strait: Influences of Sampling Interval and Observation Duration

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Internal tides (ITs) usually exhibit incoherent characteristics during their propagation. However, estimations of incoherent ITs from different platform (mooring and satellite) observations exhibit discrepancies, partly due to their different sampling intervals and observation durations.

Electrical Conductivity of Amorphous and Molten CaCO3 at High Pressures and Its Implications for Mantle Conductivity Anomalies

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Impedance spectrometry experiments have been conducted on CaCO3 up to 15 GPa and 2,100 K to identify its state under high pressure. The melting temperature of CaCO3 was also determined by the falling of a Re sphere observed via X‐ray radiography. The phase transition from aragonite to the amorphous phase does not cause a leap in the Electrical
