Union City OK , 24 May 1973, looking NW. Wide angle view of a classic supercell updraft base, wall cloud and tornado, in its early lifespan. This violent tornado did F4 damage. Intercept teams from NSSL positioned themselves all around the mesocyclone and documented the tornado on film, while beams from the Norman research Doppler radar passed overhead, in the most intensive scientific observation of a tornado conducted to that time.
