Advancing Toward Gray Zone: Evaluation of Tropical Cyclones in Key Basins With the 12.5 km High Resolution CAS FGOALS‐f3 Model

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract State‐of‐the‐art climate models are approaching gray‐zone resolutions that can improve the representation of tropical cyclones (TCs), but the extent of these gains remains uncertain. This study evaluates the effect of spatial resolution, particularly near the gray‐zone, using three resolution configurations of the Chinese Academy of Sciences ...

Improved Simulations of the Quasi‐Biennial Oscillation in the Lower Stratosphere of an Earth System Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Numerical experimentation using an atmospheric configuration of the Goddard Earth Observing System (GEOS) Earth System Model is used to examine the vertical structure of the simulated Quasi‐Biennial Oscillation (QBO). Using an improved representation of the parameterized gravity wave spectrum, it is demonstrated that with sufficient vertical ...

On the Cell Broadening of Mesoscale Cellular Convection in a Well‐Mixed Boundary Layer

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Understanding what controls the horizontal scale of mesoscale cellular convection is central to explaining cloud self‐organization and its radiative impacts. Using a hierarchy of large‐eddy simulations, we investigate cell broadening in a well‐mixed boundary layer by isolating the roles of radiation, cloud microphysics, and water vapor.

Alaskan Ridge Blocking and Associated Winter Cold Conditions Over North America

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Multi‐decadal (1979–2023) analysis reveals that wintertime reductions in the meridional gradient of potential vorticity (PVy) over the Bering Sea are recurrent but episodic features of North Pacific circulation. These suppressed PVy states consistently co‐occur with amplified Alaskan ridging, weakened mid‐tropospheric westerlies and a downstream warm ...

Future Changes of European Windstorm Losses in EURO-CORDEX Simulations

Tellus: Series A, Dynamic Meteorology and Oceanography
Windstorms are one of the most important natural hazards affecting Europe. This article investigates the potential impacts of climate change on windstorm losses in Europe employing the Loss Index (LI) method.

Are West African Heat‐Lows Analogous to Dry Tropical Cyclones?

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Heat‐lows qualitatively resemble dry tropical cyclones (TCs), though their underlying physics has yet to be compared. In this study, we show that West African transient heat‐low climatology correlates well with TC potential intensity generalised over land.

Causal Impact of ENSO on Future Ozone Concentrations and Transport in the Tropical Tropopause Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Alterations in the tropopause are recognized as key signals of anthropogenic climate change and further understanding of the major drivers of future changes in the tropical tropopause layer (TTL) is crucial. Nevertheless, the causal effects of the El Niño‐Southern Oscillation (ENSO) on TTL remain elusive, particularly in a future warming ...

Stacked Cells Hypothesized for Jupiter's Atmosphere and Observed in Earth's Atmosphere

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Observations of Jupiter's atmosphere led to the hypothesis that each of Jupiter's jets is accompanied by vertically stacked overturning circulations, with their nodes at the altitude of the jet maximum. However, there is no established theory for how these stacked cells form.

Imminent Localized Precipitation Preceded by a Surge in Cloud‐Base Descent and Reflectivity

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The nowcasting of localized precipitation (LP) is often limited by insufficient observation of the vertical cloud evolution preceding rainfall. Here we systematically tracked rapid cloud development within 2 hr before LP onset, utilizing cloud data collected in 2024 from the millimeter‐wavelength cloud radar network across China, together with

Understanding and Anticipating Anomalous Surface Impacts During Large‐Scale Regimes

Meteorological Applications
Weather regimes describe the large‐scale atmospheric circulation in the mid‐latitudes in terms of a few circulation states that modulate regional surface weather conditions on time scales of multiple days to a few weeks.
