Understanding the Response of the Quasi‐Biennial Oscillation to Carbon Dioxide and Sea Surface Temperature Increases in Aqua‐Planet Simulations

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) of the tropical stratospheric zonal winds influences tracer transport, the stratospheric polar vortex, and extra‐tropical surface variability. However, the response of the QBO to increasing greenhouse gas concentrations is still uncertain.

3D Water Vapor Signature of Tropical Storms: GNSS Tomography of the 10 Most Severe Rainfall Events in Hong Kong 2015–2025

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Monitoring water vapor during extreme events is crucial for understanding atmospheric physics, as well as for improving the prediction of severe weather and enhancing early warning systems. The major gap in monitoring water vapor during extreme events lies in the limited spatial and temporal resolutions of existing techniques.

How to Predict the Phase Shift of “Warm Arctic–Cold Eurasia” Pattern Between Early and Late Winter?

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The “Warm Arctic−Cold Eurasia” (WACE) pattern frequently undergoes distinct phase reversals between early and late winter, posing significant challenges for climate prediction. Current state‐of‐the‐art real‐time prediction models exhibit limited skill in forecasting WACE reversals, and the main reason is poor representation of key atmospheric ...

Impact of tropospheric modelling on GNSS vertical precision: an empirical analysis based on a local active network

open access: yesInternational Journal of Digital Earth, 2018
The troposphere affects Global Navigation Satellite System (GNSS) signals due to the variability of the refractive index. Tropospheric delay is a function of the satellite elevation angle and the altitude of the GNSS receiver and depends on the ...

Comparison of Tropospheric Horizontal Gradients Modeling Methods in LEO Constellation Augmented GNSS Precise Point Positioning

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
With the improvement in GNSS data processing accuracies, the selection of optimal asymmetric troposphere delay modeling method becomes essential, especially during the period of severe weather events and with the development of low Earth orbit (LEO ...

Unified channel modeling method for troposphere-ionosphere cross-media HF over-the-horizon propagation

open access: yesTongxin xuebao
Traditional skywave over-the-horizon (OTH) channel modeling inadequately accounted for tropospheric radio wave propagation effects, failing to effectively characterize the geometric distortion of ionosphere-troposphere cross-medium long-distance ...
