Characteristics of 1 year of observational data of VOCs, NO_x and O₃ at a suburban site in Guangzhou, China [PDF]

Atmospheric Chemistry and Physics, 2015
Guangzhou, one of China's megacities, is beset with frequent occurrence of high-concentration ozone events. In this study, online instruments were used to simultaneously monitor ozone, nitrogen oxides (NOx) and volatile organic compounds (VOCs) at GPACS (

Why are severe weather and anomalous climate events often associated with the orthogonal convergence of airflows?

Weather and Climate Extremes, 2023
Severe weather often occurs in the areas where different cold-warm and dry-wet air masses converge orthogonally. The orthogonal convergence of two-adjacent air parcels can be observed from planetary-scale to synoptic-scale and meso-scale circulations ...

Impact of a subtropical high and a typhoon on a severe ozone pollution episode in the Pearl River Delta, China [PDF]

Atmospheric Chemistry and Physics, 2022
A record-breaking severe ozone (O3) pollution episode occurred in the Pearl River Delta (PRD) in early autumn 2019 when the PRD was under the influence of a Pacific subtropical high followed by Typhoon Mitag.

10–30‐day moist static energy evolutions related to the persistent heavy rainfall event in different stages of flood season over South China

Atmospheric Science Letters, 2023
In this study, the flood season in South China (SC) was divided into three stages: two first rainy seasons (FRSs) around the South China Sea summer monsoon onset and one second rainy season when Typhoon prevails, denoted as FRS1, FRS2, and SRS ...

A high-order conservative collocation scheme and its application to global shallow-water equations [PDF]

Geoscientific Model Development, 2015
In this paper, an efficient and conservative collocation method is proposed and used to develop a global shallow-water model. Being a nodal type high-order scheme, the present method solves the pointwise values of dependent variables as the unknowns ...
