B/W Movies of Severe Storms and Tornados on April 23, 1968


Availability: Data Accessible Elsewhere

Time span: 1968-04-23 to 1968-04-23


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 tornado and severe storm conditions (including a snow storm) as observed by satellite on April 23, 1968, during the spring NASA-ESSA joint tornado watch experiment. These tornado or sever storm conditions ware depicted through time-lapse photography from pictures taken by the ATS 3 Multicolor Spin Scan Cloud Camera (MSSCC). Each film sequence is made up of individual pictures, each requiring approximately 20 minutes of scan time to procude. In a single day (10 hours of observations) about 32 individual pictures are recorded. Since a single sequence has a showing of 2 sec or less, each sequence is repeated 4 to 5 times to allow for interpretive viewing. The upper-level wind field associated with sever storm conditions is revealed through the cloud motion depicted in theses short film sequences. The movie is in black and white with superimposed color annotation (i.e., titles, labels, geographic grids and synoptic charts). Individual tornadoes are identified by red dots. The movie presents local views of various Great Lakes, the Rocky Mountains, the central United States, and in Mexico. This movie (NASA release no. 68-713) is available for viewing at NSSDC and may be obtained at cost from the National Audio-Visual Center, Suitland, MD.
