Impacts of Wildfire Smoke on Stratocumulus Clouds and Their Diurnal Cycle Using WRF‐Chem Modeling

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract This study applies the WRF‐Chem model to examine the variability of marine stratocumulus clouds associated with wildfire smoke in the western United States, by comparing model simulations with and without wildfire emissions during the extreme fire season of 2021.

A model intercomparison analysing the link between column ozone and geopotential height anomalies in January [PDF]

Atmospheric Chemistry and Physics, 2008
A statistical framework to evaluate the performance of chemistry-climate models with respect to the interaction between meteorology and column ozone during northern hemisphere mid-winter, in particularly January, is used.

Characteristics and Predictability of Extreme Precipitation Related to Atmospheric Rivers, Mesoscale Convective Systems, and Tropical Cyclones in the U.S. Southeast

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract The Southeastern United States (SEUS) region has lower extreme quantitative precipitation forecast (QPF) skill compared to the northeastern or western United States. Previous studies have reported that the extreme precipitation events (EPEs) with high integrated vapor transport (IVT) have higher QPF skill than those with low IVT in the SEUS ...

Understanding the Intricacies of Model Biases in Storm‐Related Extreme Precipitation Using CMIP6

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract This paper evaluates the biases, defined as deviations from ERA5, in extreme precipitation linked to tropical cyclones (TCs), extratropical cyclones (ETCs), and atmospheric rivers (ARs) in Coupled Model Intercomparison Project Phase 6 (CMIP6) models during 1985–2014.

Stratospheric Impacts on Weather Regimes Following the 2018 and 2019 Sudden Stratospheric Warmings

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Major disruptions of the stratospheric polar vortex can improve subseasonal forecast skill for surface climate, as negative North Atlantic Oscillation‐like (NAO−) states can follow sudden stratospheric warmings (SSWs). Yet most insights come from observational studies or large operational forecast archives.

Machine‐Learning (ML)‐Physics Fusion Model Accelerates the Paradigm Shift in Typhoon Forecasting With a CNOP‐Based Assimilation Framework

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract In this study, we develop an advanced hybrid forecasting system for short‐term (0–120 hr) typhoon predictions, seamlessly integrating the FuXi machine‐learning model with the physics‐based Shanghai Typhoon Model (SHTM). By employing spectral nudging, the hybrid FuXi‐SHTM model leverages FuXi's robust large‐scale forecasting capabilities ...

Western North Pacific Monsoon Gyres: A New Identification Approach, Interannual Variability, and Seasonal Prediction

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Western North Pacific (WNP) monsoon gyre (MG) events are an important large‐scale driver of tropical cyclone (TC) activity. However, prior studies have mostly focused on case‐specific analyses using a subjective MG identification. There is currently limited understanding of MG variability at interannual and longer time scales.
