Release Title:

|
The highest lightning flash rates recorded during the May 3, 1999, tornado outbreak -- as many as 90 in-cloud flashes per minute -- were recorded during the storm's passage over Stroud, Oklahoma. Here, the TRMM satellite and Lightning Imaging Sensor record radar, infrared and microwave data on the tornadic storms threatening the Stroud region, followed by a recording of lightning strike patterns during the storms.

| In this animation, lightning flashes -- recorded during the NASA Lightning Imaging Sensor's pass over storms moving through Oklahoma in October 1998 -- are overlaid on high-resolution infrared cloud-top data from the orbiting Tropical Rainfall Measuring Mission (TRMM) satellite. High flash rates visible in the heaviest storm areas may indicate the potential for tornado formation. With an optical sensor locked into geostationary orbit over the Earth, such useful information would be available continuously to meteorologists and other professional stormwatchers.

| NASA's Optical Transient Detector records an annual cycle of lightning patterns around the planet. The animation makes apparent the cyclical rise in lightning during summer months in the Northern and Southern hemispheres. (Animation courtesy of the Global Hydrology and Climate Center.) | |
