On the influence of atmospheric super-saturation layer on China's heavy haze-fog events

Schematic diagram of 3-D model for low-level super-saturation layer (H_SSL) and pollution mixing layer (H_PMLs) in the pollution hotspots (NCP, YRD and PRD and SCB) in China. Light blue scarping down to the bottom of the vertical plane (B) is iso-θe surface for air adiabatic uplift; on the upper left corner of B-plane is the tephigram.394
