An observational analysis of the eastern tropical Pacific Shallow Meridional Circulation using YOTC data and pilot balloons from Isla del Coco, Costa Rica

Marine and Fishery Sciences
The low-level circulation of the atmosphere over Isla del Coco has been studied and the presence of a northerly wind at low levels of the atmosphere in the eastern tropical Pacific, in addition to the deep Hadley circulation cell, has been confirmed ...

Projected near term changes in the East Asian summer monsoon and its uncertainty

Environmental Research Letters, 2019
Changes in the East Asian summer monsoon (EASM) during the mid-21st century relative to present day are simulated in two related models GOML1 and GOML2. Both models are the atmospheric components of two state-of-the-art climate models coupled to a multi ...

Decreasing Translation Speed of Rapid Expansion Tropical Cyclones Over the Western North Pacific

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The overall destructiveness of tropical cyclones (TCs) depends not only on their intensity but also on storm size and translation speed, which together determine the spatial extent and duration of impacts. However, variations in translation speed of TCs undergoing rapid expansion (RE) over recent decades remain poorly understood.

The Role of the Ocean in the Seasonal Cycle of the Hadley Circulation

, 2006
The influence of ocean heat transport on the seasonal cycle of the Hadley circulation is investigated using idealized experiments with a climate model. It is found that ocean heat transport plays a fundamental role in setting the structure and intensity ...

Decadal Reversal of Eurasian Winter Temperature Trend Linked to North Atlantic Climate Variability

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The long‐term trend of Eurasian winter surface air temperature has undergone a distinct decadal change, shifting from a pronounced cooling trend between the late 1980s and late 2000s to a subsequent warming trend. This study demonstrates that this trend reversal is partly driven by decadal changes in North Atlantic sea surface temperature (SST)

The Maintenance of the Longitudinal Subtropical Jet Structure During Austral Winter

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The austral winter subtropical jet maintenance is analyzed by comparing the observed upper tropospheric zonal momentum budget with an idealized aquaplanet model simulation with localized tropical heating in the summer hemisphere. The model and observations show great similarity, demonstrating the dominant role of localized tropical convection ...

Recalibrated projections of the Hadley circulation under global warming

Environmental Research Letters
Climate models project a weakening and expansion of the Hadley circulation (HC) under global warming but with considerable spread in the magnitude of these changes.

Does Polar Warming Asymmetry Exist in Bathy‐Planet Experiments?

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Ocean bathymetry and continental geometry shape ocean circulation, but whether these geographic constraints can sustain polar warming asymmetry in a fully coupled climate system remains unclear. Here we construct a fully coupled “bathy‐planet” configuration (BATHY), in which continental topography is removed and most land surfaces are replaced

Spurious Drifts in the ITCZ Location and Associated Atmospheric Circulation in Decadal Climate Predictions

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Decadal predictions are affected by initialization shocks and drift, typically diagnosed in ocean circulation or temperature. It is not known, however, to what extent the drift can affect atmospheric dynamics. Here we investigate how the drift causes spatial shifts in the location of key large‐scale atmospheric circulation features such as the

Recent poleward shift of tropical cyclone formation linked to Hadley cell expansion

, 2018
Recent research indicates that the annual-mean locations of tropical cyclones have migrated toward higher latitudes. Concurrently, an anthropogenically forced tropical expansion has been observed, yet the connection between the two processes remains ...
