Modernization of Atmospheric Physics Parameterization in Canadian NWP

Journal of Advances in Modeling Earth Systems, 2019
Atmospheric physics is represented in numerical models by parameterizations that use resolved‐scale information to estimate the effects of physical processes on the atmospheric state.

Comparison of Atmospheric Turbulence Characteristics over Sea Surface and Land Surface before, during, and after Typhoons

Atmosphere, 2022
The goal of the paper is to reveal discrepancies of turbulent variables over different surfaces (sea, island, land) based on the measurements taken on three towers during (including before and after) seven typhoon episodes from 2008 to 2018.

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 (

Prediction Challenges From Errors in Tropical Pacific Sea Surface Temperature Trends

Frontiers in Climate, 2022
Models in the North American Multi-Model Ensemble (NMME) predict sea surface temperature (SST) trends in the central and eastern equatorial Pacific Ocean which are more positive than those observed over the period 1982–2020.

The role of anthropogenic aerosols in the anomalous cooling from 1960 to 1990 in the CMIP6 Earth system models [PDF]

Atmospheric Chemistry and Physics, 2021
The Earth system models (ESMs) that participated in the sixth Coupled Model Intercomparison Project (CMIP6) tend to simulate excessive cooling in surface air temperature (TAS) between 1960 and 1990.

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 ...
