Optical Transient Detector (OTD) Observations of a Tornadic ThunderstormTotal lightning observations made by the Optical Transient Detector (OTD) of a tornadic thunderstorm that occurred over Oklahoma 17 April 1995 are presented. The average flash rate of the tornadic storm during the 3.2 min observation period was 45 flashes min.with a flash rate density of 1.16 x 10(exp -4)/s sq km. The total flash rate was almost 18 times higher than the cloud-to-ground rate measured by the National Lightning Detection Network (NLDN). In addition. total lightning rates were observed to decrease prior To tornadic development.
