Specification of P M 2 . 5 transmission characteristics is important for pollution control, policymaking and prediction. In this paper, we propose weights for motif instances, thereby to implement a weighted higher-order clustering algorithm for a weighted, directed P M 2 . 5 network in the Yangtze River Delta (YRD) of China. The weighted, directed network we create in this paper includes information on meteorological conditions of wind speed and wind direction, plus data on geographic distance and P M 2 . 5 concentrations. We aim to reveal P M 2 . 5 mobility between cities in the YRD. Major potential P M 2 . 5 contributors and closely interacted clusters are identified in the network of 178 air quality stations in the YRD. To our knowledge, it is the first work to incorporate weight information into the higher-order network analysis to study P M 2 . 5 transport. [ABSTRACT FROM AUTHOR]
