Meteorological Tsunamis: From Local Hazard to Global Relevance

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Research on meteorological tsunamis or meteotsunamis—long ocean waves in the tsunami frequency band generated by propagating atmospheric disturbances which resonantly enhance ocean waves—has grown significantly in recent decades. This expansion is due to progress in (a) ocean and atmospheric measurements, including advanced instrumentation ...

Effects of Dynamical and Diabatic Processes on Stationary and Transient Kelvin Waves

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract Atmospheric Kelvin waves (KWs) are influenced by both tropical convective heating and dry dynamical processes, but the relative contributions of these mechanisms remain uncertain. This study examines the effects of various processes on stationary and transient KWs in ERA5 data using a global, multivariate framework that identifies KWs based on

Stagnation of Atmospheric Circulation Leads to Historically Prolonged Extreme Rainfall Event Over Northwestern India in August 2024

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 21, 16 November 2025.
Abstract Northwestern India (NWI) received anomalously heavy rainfall from 21 to 30 August, 2024, despite the monsoon being in a break phase. This study reveals how midlatitude dynamics triggered this unusual event. Using reanalysis, we perform a moisture budget analysis and local wave activity (LWA) diagnostics and find that the enhanced mid ...

Observations of Subduction, Downward Heat Flux and Dense Filament Collapse in the Northern Gulf of Mexico

Journal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract Submesoscale processes are important contributors to the global heat budget and generally support upward heat transport through restratification. However, in salinity‐stratified regions, such as the northern Gulf of Mexico with its influx of freshwater from the Mississippi‐Atchafalaya river system, temperature can act like a passive tracer and

Ocean Worlds Maintained by Ocean Tidal Heat Expected on Several Uranian Moons

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract In recent NASA decadal surveys, detecting oceans among Uranus' moons has been identified as a research priority in future missions. Currently, the prevailing view in planetary science is that the likelihood of finding oceans is highest on the larger moons, Titania and Oberon, due to their higher integrals of radiogenic heat sources. This study

Unveiling the Complex Structure of Vertical Mode‐Two Kelvin Waves Driving Strong Nearshore Currents in Large, Deep Lake Geneva

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract Although vertical mode‐one (V1) Kelvin waves are known to play an important role in nearshore dynamics of large lakes, observations of vertical mode‐two (V2) Kelvin waves are scarce, and their characteristics and significance are largely unknown. Combining field observations, 3D hydrodynamic modeling, and particle tracking, we demonstrate that

Origin of the Intraseasonal Current Variability and Its Interannual Modulation at 1,000 m Depth in the Eastern Equatorial Pacific Ocean

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract It has been shown that the intraseasonal variability in the eastern Pacific Ocean at the intermediate depth (∼1,000 m) has a large amplitude along the equator. However, our understanding of the origin and detailed characteristics of the Equatorial Deep Intra‐seasonal Variability (DEIV) is still limited. In this study, we use observed data near

Maintenance of Convectively Coupled Kelvin Waves: Relative Importance of Internal Thermodynamic Feedback and External Momentum Forcing

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Previous studies suggest that convectively coupled Kelvin waves (KWs) are likely maintained by two distinct processes: (a) the internal thermodynamic feedback between KW diabatic heating and temperature, and (b) the external momentum forcing from the midlatitude Rossby waves exerting on the KW zonal wind.

Composite Three‐Dimensional Biogeochemical Responses to Tropical Cyclones in the Northwest Pacific

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract We innovatively investigated three‐dimensional biogeochemical responses to tropical cyclones (TCs) in the Northwest Pacific using a composite analysis of simulations from a coupled physical‐biogeochemical model. TC‐induced upwelling and vertical mixing cause a vertical redistribution of chlorophyll a concentration (Chl‐a), increasing surface ...
