Simulation of Water Vapor Transport to the Stratosphere by Overshooting Convection

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Deep convection that penetrates the tropopause (overshooting convection) transports water vapor and other tropospheric constituents to the upper troposphere and lower stratosphere (UTLS). Overshooting convection has chemical and radiative impacts on the UTLS, including the downward transport of ozone and hydration of the stratosphere ...

How Lateral Flow Impacts Heavy Rainfall in Complex Terrain: A Composite Analysis Over the Southern Anhui Mountainous Region

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract High‐resolution modeling of terrestrial hydrological processes offers new opportunities to advance the understanding of land‐atmosphere (L‐A) interactions. To investigate the impact of soil lateral flow (LF) on heavy rainfall events in mountainous areas of the Yangtze‐Huai region, we conducted two sets of convection‐permitting WRF simulations ...

Oceanic Eddy Modulation of Wintertime Air‐Sea Coupling and Marine Atmospheric Boundary Layer Winds Over the East China Sea

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract This study examined the effects of air‐sea coupling and oceanic mesoscale eddies on wintertime low‐level wind events within the marine atmospheric boundary layer (MABL) over the Kuroshio front zone in the East China Sea. High‐resolution (eddy‐resolving, 5 km) and low‐resolution (50 km) simulations were conducted using prescribed sea surface ...

Opposing Trends in Wintertime Convective Initiation Environments of East China Driven by Anthropogenic Aerosols and Greenhouse Gases

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Winter convection can trigger severe disasters due to low temperature, yet the drivers and mechanisms of regional long‐term trends in winter convective initiation remain unclear. Using homogenized radiosonde data, we reveal the spatially divergent trends in wintertime atmospheric unstable conditions, with a significant decrease in the northern

Kalman Filter bank post-processor methodology for the Weather Research and Forecasting Model wind speed grid model output correction

International Journal of Sustainable Energy, 2019
The performance of the Weather Research and Forecasting (WRF) model, coupled with a bank of eight Kalman Filters (KFB) as a post-processor toolbox for the three hourly average WRF wind speed forecasts, is investigated and compared to the output of the ...

Model Coupling between the Weather Research and Forecasting Model and the DPRI Large Eddy Simulator for Urban Flows on GPU-accelerated Multicore Systems

, 2015
In this report we present a novel approach to model coupling for shared-memory multicore systems hosting OpenCL-compliant accelerators, which we call The Glasgow Model Coupling Framework (GMCF).

Plume‐Coupled Long‐Range Spotting Drove the Explosive Spread of the 2018 Camp Fire

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Extreme fire spread during the 2018 Camp Fire in northern California was driven by organized long‐range spotting tightly coupled to plume dynamics. Doppler radar and satellite observations reveal distinct regions of ember lofting and downwind fallout within the convective column, forming direct pathways for firebrand transport several (up to ...

Quantifying Tropical Cyclone Vertical Mass Flux and Its Relationship to Precipitation Structures Under Varying Sea Surface Temperatures

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Vertical mass flux (MF) describes the rate at which air and water vapor move upward or downward in an atmospheric column. MF is related to cloud and precipitation formation. This work examines the relationship between MF and characteristics of tropical cyclones (TCs) in idealized Weather Research and Forecasting model simulations.

Environmental Controls on the Seasonal and Spatial Variability of Submesoscale Thermal Air–Sea Coupling Over the Gulf Stream

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using an ocean‐atmosphere coupled simulation, we investigate the seasonal variability of the low‐level wind response to submesoscale (O(1–10 km)) sea surface temperature (SST) anomalies over the Gulf Stream, focusing on the respective roles of the downwind momentum mixing (DMM) and pressure adjustment (PA) mechanisms.

Improvements of Hurricane Forecast with Vortex Initialization using WRF Variational (WRF-Var) Data Assimilation [PDF]

, 2011
Although the forecasts of hurricane track have steadily improved during the past two decades, intensity forecasts remain unsatisfactory (Elsberry, 2005). Previous studies have shown that vortex structures can significantly affect the behavior of hurricane intensity (Ross & Kurihara, 1995; Willoughby & Black, 1996; Xiao et al., 2000). The initialization
