    The amplification effect of El Niño on winter heavy pollution frequency in Beijing by Mengjie Lou, Qizhong Wu, Jie Li, Huaqiong Cheng, Jiang Zhu, Lanning Wang, Zifa Wang

    Published 2025-01-01
    “…China has implemented stringent emission controls to reduce PM _2.5 pollution, but the impact of the El Niño-Southern Oscillation (ENSO) on regional heavy pollution events in this process remains understudied. We use the WRF-SMOKE-CMAQ modeling system to innovatively reconstruct the meteorologically-driven trends of PM _2.5 pollution in Beijing from 2013 to 2023 by setting up fixed emission scenarios and minimize the interference of anthropogenic emissions. …”
