Sprite Model Experiments and Observations of Winter Sprites
The experiments for the optical and spectral characteristics of the long gap air discharges under low pressure as the model of red sprite or blue jet have been reported. The results are compared with the characteristics of sprites. The experimental air pressure have been varied from 0.0075Torr to 20Torr, corresponding to the altitude of 80km and 25km, respectively. Using the band pass filter which cut-off wave length is 500nm, the relationship of between whole light flux in the range of 500nm and 800nm and the air pressure has been studied. The highest light flux intensity occurs at about 0.08Torr that corresponds to the altitude of 65-67km. Moreover, winter sprites in Japan Sea coastal area have been observed by a high intensity video camera system.
