16-mm Movies of Tornadoes on April 19, 1968


Availability: Data Accessible Elsewhere

Time span: 1968-04-19 to 1968-04-19


This 16-mm silent movie was produced for NASA by the Satellite and Mesometeorology Research Project of the University of Chicago. The movie consists of numerous short film sequences of tornadoes or tornado conditions as observed by satellite on April 19, 1968, during the spring NASA-ESSA joint tornado watch experiment. These tornadoes or tornado conditions are depicted through time-lapse photography from pictures taken by the ATS 3 Multicolor Spin Scan Cloud Camera (MSSCC), while the satellite was near 84 deg W longitude. Each film sequence is made up of individual pictures, each requiring approximately 20 minutes of scan time to produce. In a single day (10 hours or observations) about 32 individual pictures are recorded. Since a single sequence has a showing time of 2 sec or less, each sequence is repeated 4 to 5 times to allow for interpretive viewing. The upper-level wind fields associated with tornadoes are revealed through the cloud motions depicted in these short film sequences. The movie is in black and white with superimposed color annotation (i.e., titles, labels, and geographic grids). The individual tornadoes are identified by red dots. The movie presents local views of various tornadoes and tornado conditions observed near the Gulf Coast states, the Southeast, the Rocky Mountains, the Great Lakes, Northern Mexico, and Cuba. This movie (NASA index no. 04112) is available for viewing at NSSDC and copies may be obtained at cost from the National Audio-Visual Center, Suitland, MD.
