Drivers of F‐Region Ionosphere Tidal Variability Caused by the Madden Julian Oscillation: Separating E‐Region Dynamo and Field‐Aligned Wind Effects

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The Madden–Julian Oscillation (MJO), a recurring intraseasonal (30–96 days) disturbance in the troposphere, strongly influences the E‐region and F‐region ionosphere through its modulation of atmospheric tides. Among these, the diurnal eastward wave number 3 (DE3) tide, driven by MJO‐modulated latent heating, carries MJO signals upward into the

Effects of Recurving Western North Pacific Tropical Cyclones on Downstream Ridges Over Pacific‐Western North America

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Recurving tropical cyclones (TC) in the Western North Pacific can affect the atmospheric circulation over Pacific‐Western North America (PWNA) via interactions with the midlatitude circulation. Using reanalysis and tropical cyclone best‐track data, we examine how recurving TCs that make extratropical transition modulate 500‐hPa ridge ...

Improving Medium‐Range Temperature Forecast Over the Tibetan Plateau Through Spatially Adaptive Fusion

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Tibetan Plateau exerts profound impacts on the global weather system, whereas its medium‐range temperature forecast is challenging due to the complex topography. This study introduces Swin Transformer Fusion (STF), a spatially adaptive ensemble strategy that integrates forecasts from numerical weather prediction models (EC, GFS) and large ...

Baroclinic geostrophic adjustment in a rotating circular basin

open access: yes, 2004
Baroclinic geostrophic adjustment in a rotating circular basin is investigated in a laboratory study. The adjustment process consists of a linear phase before advective and dissipative effects dominate the response for longer time. This work describes in

Revisiting ENSO Regime Shift Around 2000: A Perspective From Recharge Oscillator‐Based Linear Inverse Model

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Classic Recharge Oscillator (RO) studies typically rely on spatially averaged indices, which capture the temporal characteristics of ENSO mode but provide limited information on its spatial structure. To address this limitation, a Recharge Oscillator‐based Linear Inverse Model (RO–LIM) was developed by embedding the recharge–discharge physics ...

Weather Regimes Preclude the Observation of a Southern Annular Mode Signal in Two Coastal East Antarctic Ice Cores

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract The Southern Annular Mode (SAM) represents the dominant pattern of climate variability in the extratropical Southern Hemisphere. However, its signature in coastal East Antarctic ice core records is unclear. A daily synoptic typing data set for the southern Indian Ocean constructed using self‐organizing maps on 500 hPa daily geopotential height

Interannual Variations of Precipitation Events at Dome Fuji Station, Antarctica

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Precipitation is key to the water budget of inland Antarctica, with extreme precipitation events strongly influencing snowfall and surface climatology. To investigate the contribution and trends of such events at Dome Fuji station (DF) in inland Antarctica, this study analyzed precipitation variability using the ERA5 product validated against ...
