Short summary
During the heavy pollution process, there are overestimations regarding the exchange between the atmosphere and surface since the normal calculation of turbulent fluxes includes the impact of sub-mesoscale motion. The intermittent turbulence intensity is closely related to the concentration of PM2.5. The intermittency is weaker over the complex surface condition than over the flat terrain, and urbanization reduces the degree of weakening in turbulent exchange during the heavy pollution process.
