SUMMARY:Adventure Engineering: Life and Work at the Home of the World’s W
 orst Weather
DESCRIPTION:A Lecture by Jill Schoof\n\nAdventure Engineering will give an
  idea of the great beauty and variety of weather at the Summit of New Engl
 and’s highest mountain\, and of the great challenge and adventure of lif
 e and research work at the world-famous mountaintop observatory.  Profess
 or Schoof is a founding member of the Center for Wind\, Ice\, and Fog Rese
 arch at the Mount Washington Observatory.  She will describe some of the 
 very robust wind measurement instruments she designed and built with her s
 tudents for use under what are generally considered some of the most extre
 me weather conditions found anywhere.\n\nPreregistration is required and a
  ZOOM link will be sent to participants.\n\nPhoto wikicommons Photo taken 
 by Michael Davidson on April 7\, 2004.\n\n***\n\nThe summit of Mount Washi
 ngton is unique as well as beautiful\, as it is subject to extremes of met
 eorological\, climatic\, biological\, and ecological conditions not found 
 elsewhere outside the polar and arctic regions.  Summit weather is severe
 .  Over the 43-year interval from 1935-1978\, for example\, mean annual p
 recipitation at the Observatory was 83.55 inches and mean annual snowfall 
 was 248 inches.  A snowfall of 566.4 inches during the 1968-69 season bro
 ke a national snowfall record.  Icing is extreme (and beautiful)\, and fi
 ve feet of rime ice can grow on surfaces overnight.\n\nFor some part of th
 e day\, the summit is in cloud or fog at least 300 days of the year.   T
 he temperature measured at the summit never rises over 72 degrees F\; the 
 lowest recorded was -47 degrees Fand the average is 27 degrees F.  The me
 an hourly wind speed is 35.1 mph.  “Century days” (when wind gusts ex
 ceed 100 mph) are frequent in winter and early spring.  Wind chill factor
 s are off the charts and can often be lethal.  The highest wind velocity 
 recorded was 231 mph\, a world record\, measured at the Observatory on Apr
 il 12\, 1934.
