Does the Negative Arctic Oscillation Always Favor Winter PM2.5 Diffusion in North China?

引用

Journal of Meteorological Research 2024年第5期 954-968页

作者： yueyue YU Zhengfei CUI Haishan CHEN Guotao LIU Chunhua shi Jian RAO Key Laboratory of Meteorological Disaster Ministry of Education (KLME)/Joint International Research Laboratory of Climate and Environment Change (ILCEC)/Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disasters (CIC-FEMD)Nanjing University of Information Science&Technology Department of Geography University College London (UCL)

Previous studies have reported a close relationship between the negative Arctic Oscillation（AO） and the PM2.5(particulate matter with a diameter of2.5μm or less) diffusion in North China in winter. Using the North China regional mean meridional wind at 850 hPa derived from the ERA5（ECMWF Reanalysis version 5） reanalysis data in1979–2022 as a useful substitute for station observed PM2.5concentration（since the latter is available only since2014）, our study detected strong/weak northerly events representing the abnormal PM2.5diffusion/accumulation events, and revisited the AO–PM2.5diffusion relationship in North China during 1979–2022. The results show that only when the AO was characterized by a 2-month continuously negative/positive phases and with twin peaks respectively before and after the diffusion/accumulation events, would there be higher occurrences of the abnormal PM2.5diffusion/*** second peak of negative AO acted to prolong the strong northerly winds by an average of 2 days. Further analysis reveals that the AO with twin peaks always has a footprint in the stratospheric northern annular mode（NAM） during the abnormal PM2.5events, and the coupling between the stratosphere and troposphere plays a critical role in the second peak of AO. Vertical propagation of baroclinically amplifying waves leads to changes in isentropic meridional mass fluxes in the stratosphere following the changes in the troposphere. The stronger/weaker poleward mass fluxes increase/decrease the polar mass in the stratosphere, which dominates the total column air mass changes and leads to the second peak of AO. Considering the subseasonal predictability of the stratospheric NAM based on existing evidence, particular attention should be paid to these AO-related abnormal PM2.5diffusion and accumulation events in North China because they might be more predictable at a longer lead time.
