Atmospheric Water Vapor and Precipitation Coupling in Southwestern South America

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Most studies linking atmospheric water vapor and precipitation emphasize short records, tropical regions, or the Northern Hemisphere. Long‐term variability of water vapor and its coupling with precipitation remain poorly understood across strong latitudinal and climatic gradients.

Constructing High-Precision and Spatial Resolution Precipitable Water Vapor Product Using Multiple Fusion Models

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Water vapor is a critical parameter in the earth's climate system, affecting precipitation and global warming. Precipitable water vapor (PWV) is a measure of atmospheric water vapor content that can be obtained by multiple methods.

Aerosols Shape the Vertical Structure of Convective Overshooting in Southeast Asia Through Microphysical Processes

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Convective overshooting significantly influences atmospheric material and energy cycles and can cause severe social impacts; nevertheless, aerosol effects on its microphysical structure and associated extreme weather remain unclear. Using a more accurate algorithm of detecting convective overshooting and 10 years of high‐resolution data, this ...

Research on Applicability of GNSS PWV Data in Northeast China and Its Application in Intelligent Precipitation Prediction

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract Atmospheric water vapor is an important factor in the formation and evolution of extreme weather events, such as heavy rainfall, typhoons, and major droughts and floods. We analyzed the applicability of precipitable water vapor (PWV) values from the Global Navigation Satellite System Meteorology (GNSS/MET) stations in northeastern China.

Analysis of the Synergistic Effect of Water Vapor, Thermodynamics, and Dynamics of the Heavy Rainfall Over Henan Province, China in July 2021

Meteorological Applications, Volume 32, Issue 5, September/October 2025.
In this study, a record‐breaking rainfall is analyzed based on the observation data and reanalysis data. The overlay of precipitation provided by both dynamic delivery from the southeast and cloud microphysical production over Zhengzhou was the main cause of the rainfall under the background of an atypical weak environmental field. ABSTRACT During July

Accuracy Assessment and Rainfall Intensity Response Mechanisms in GNSS Real‐Time PPP Water Vapor Retrieval: Coupling Effects of Multi‐Source Real‐Time Products and Meteorological Conditions

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The Global Navigation Satellite System (GNSS) real‐time Precise Point Positioning (PPP) technology offers a highly efficient approach for atmospheric Precipitable Water Vapor (PWV) monitoring and extreme weather warning. However, its retrieval accuracy is limited by the performance of orbit and clock products, as well as the coupling effects ...

Impact of Assimilating GPS Precipitable Water Vapor on Simulations of Two North American Monsoon Convective Events Using Observing System Simulation Experiments

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 16, 28 August 2025.
Abstract This study evaluates the impact of assimilating precipitable water vapor (PWV) within an observing system simulation experiment (OSSE) framework to improve forecasts of monsoonal mesoscale convective systems (MCSs) in Arizona. Two contrasting case studies differing in convective forcing, longevity, intensity, and coverage are analyzed using a ...
