Summary

The features of the Fargo tornadoes and the meteorological situations producing them are studied in three scales: macroscale, dealing with the precipitation and tornado distribution over three-fourths of the United States; mesoscale analysis of North and South Dakota and of the rotating cloud which produced four tornadoes as it moved over the Fargo area; and, finally, microscale features of the tornado itself. These analyses are presented in an animated 16 mm motion picture. Included in this report are the results of the computed cyclostrophic wind speed and rotational speed of the funnel of the Fargo tornado. A proposed mechanism of an irreversible process taking place inside the inflowing air toward the tornado funnel is also presented.
