Influence of the upper gravity-wave damping layer on precipitation over complex terrain

open access: yesFrontiers in Environmental Science, 2022
The upper boundary condition of a numerical model can significantly influence the model prediction results. This study used the Weather Research and Forecasting model to introduce the Rayleigh damping layer in the complex terrain of southern Gansu, China.

Insights into characteristics and formation mechanisms of secondary organic aerosols in the Guangzhou urban area [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Emission controls have substantially brought down aerosol pollution in China; however, aerosol mass reductions have slowed down in recent years in the Pearl River Delta (PRD) region, where secondary organic aerosol (SOA) formation poses a major challenge

The role of empirical space-weather models (in a world of physics-based numerical simulations) [PDF]

open access: yes, 2018
Advanced forecasting of space weather requires prediction of near-Earth solar-wind conditions on the basis of remote solar observations. This is typically achieved using numerical magnetohydrodynamic models initiated by photospheric magnetic field ...
