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 ...

An Analytical Formula for Potential Water Vapor in an Atmosphere of Constant Lapse Rate

Terrestrial, Atmospheric and Oceanic Sciences, 2012
Accurate calculation of precipitable water vapor (PWV) in the atmosphere has always been a matter of importance for meteorologists. Potential water vapor (POWV) or maximum precipitable water vapor can be an appropriate base for estimation of probable ...

Precipitable Water Vapor Trends by Layer Over Florida [PDF]

Precipitable Water Vapor (PWV) is the total amount of water vapor contained in a vertical column of the atmosphere. The PWV is an indicator of how much water is available for precipitation (Trenberth et al. 2005).
