Toward Improved Tropical Cyclone Forecasting: An Optimized Strategy Combining Dynamic Initialization and Bogus Data Assimilation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract In numerical weather prediction, dynamic initialization (DI) of tropical cyclones (TCs) and bogus data assimilation (BDA) are two widely used vortex initialization methods, both of which substantially affect the track and intensity of simulated TCs.

Moisture Recycling over the Iberian Peninsula: The Impact of 3DVAR Data Assimilation

Atmosphere, 2019
In this paper, we have estimated the spatiotemporal distribution of moisture recycling over the Iberian Peninsula (IP). The recycling ratio was computed from two simulations over the IP using the Weather Research and Forecasting (WRF) model with a ...

The Impact of Nocturnal Boundary Layer Height on Daytime Surface Particulate Nitrate Increases by Vertical Transport From the Residual Layer

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Particulate nitrate (pNO3−) has become a critical air‐quality issue, with pronounced morning increases in surface concentrations attributed to downward transport from upper layer. However, how the nocturnal boundary layer evolution modulates this process remains unclear.

Contrasting Mechanisms of Heatwave‐Ozone Pollution Compound Events and Independent Heatwave Events in the Yangtze River Delta

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Heat waves do not always coincide with ozone pollution, yet the mechanisms controlling their divergence remain insufficiently understood. Here, we investigate why some heat waves evolved into heatwave‐ozone pollution compound events (HWOP), whereas others remained isolated heat wave events (IHW), over the Yangtze River Delta during summer 2024.

An Analysis of Hurricane Eyewall Ice Using a Novel Lagrangian Trajectory and Growth Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Ice crystals in tropical cyclones (TCs) remain infrequently observed and difficult to model using Eulerian microphysics parameterizations. To better understand TC eyewall ice crystal processes, the Ice Crystal Trajectory Growth (ICTG) model, previously applied to an idealized squall line, was used to simulate Lagrangian ice crystal ...

Strong Sensitivity of Simulated Biomass Burning Aerosol Transport and Radiative Effects Over the South Atlantic to Carbonaceous Aerosol Aging and Particle Density

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Biomass burning aerosol (BBA) impacts climate through aerosol‐cloud‐radiation interactions, but models disagree on the sign and magnitude of BBA radiative effects. We quantify the sensitivity of BBA radiative effects and transport to three BBA‐relevant processes and properties: parameterized oxidative aging of organic aerosol (OA), a combined ...

Root Dynamics Mitigate Warm and Dry Biases Over the Central United States

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The central United States frequently exhibits warm and dry biases in simulations of summertime conditions, a persistent feature that remains unresolved. While previous studies linked these biases to misrepresented surface energy exchanges, the role of belowground processes remains poorly understood.
