Multi-Scale Meteorological Impact on PM_2.5 Pollution in Tangshan, Northern China.

ABSTRACT: Tangshan, a major industrial and agricultural center in northern China, frequently experiences significant PM_2.5 pollution events during winter, impacting its large population. These pollution episodes are influenced by multi-scale meteorological processes, though the complex mechanisms remain not fully understood. This study integrates surface PM_2.5 concentration data, ground-based and upper-air meteorological observations, and ERA5 reanalysis data from 2015 to 2019 to explore the interactions between local planetary boundary layer (PBL) structures and large-scale atmospheric processes driving PM_2.5 pollution in Tangshan. The results indicate that seasonal variations in PM_2.5 pollution levels are closely linked to changes in PBL thermal stabilit
