Histograms of meteorological parameters in the glow-detection cases. a Surface temperature measured by AMeDAS stations. b The temperature at 850 hPa extracted from MSM. c Lapse rate between surface and 850 hPa height calculated with MSM. d Wind direction derived with radar images. The wind direction is where the wind comes from clockwise. For example, the direction 270\(^{\circ }\) indicates that wind comes from the west toward the east
