Bow Echo Discovered

After the storm, Dr. T. Theodore Fujita became aware of the extreme wind damage over northern Wisconsin and decided to conduct an investigation. He noticed that there were three areas of extreme damage from northeastern Minnesota to extreme northwestern Wisconsin, and then two more areas of forest blowdowns extending from Hayward to Rhinelander.

He then went back and looked at the radar echos, and he noticed that they evolved into a bow signature. It was during this investigation that Dr Fujita discovered the bow or spearhead radar echo.

Famous quotes containing the words bow, echo and/or discovered:

    I never knowed how clothes could change a body before. Why, before, he looked like the orneriest old rip that ever was; but now, when he’d take off his new white beaver and make a bow and do a smile, he looked that grand and good and pious that you’d say he had walked right out of the ark, and maybe was old Leviticus himself.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    True ease in writing comes from art, not chance,
    As those move easiest who have learn’d to dance.
    ‘Tis not enough no harshness gives offence,
    The sound must seem an echo to the sense:
    Alexander Pope (1688–1744)

    I had always imagined that Cliché was a suburb of Paris, until I discovered it to be a street in Oxford.
    Philip Guedalla (1889–1944)
