Evolution and advection of the KH billow under favorable background condition. (a) Schematic diagram of a possible KH-billow evolution scenario given the winds observed at Thiruvananthapuram. The false color background gradient schematically underscores the complex chemical/dynamical interplay in producing the Na distribution in the MLT region. (b) Pictogram describing how the deformed KH billow is advected with background wind and created a ‘λ image ’ type structure in the lidargram over Gadanki.
