Question
During the winter of 2011, a large and powerful winter storm hit Illinois very hard. Chicago saw a large blizzard that standard cars on Lake Shore Drive as snowdrifts 3-4 feet tall stopped all traffic. Students at the U of I had to deal with 7 inches of sleet, while just to the south, students at Eastern Illinois University saw 2 inches of ice accumulate from a freezing rain event. Finally, southern Illinois had to deal with flooding rains! The image below shows 4 separate soundings that are each labeled with a letter. The solid black line on each sounding represents the temperature profile during the height of the winter storm in Illinois on Feb 2, 2011. The red line represents the 0 degree C (32 degree F) isotherm. To the right of the red line, temperatures are above freezing and to the left, temperatures are below freezing. Match the sounding to the location based upon the description above. Chicago Blizzard: ____ U of I Sleet: ____ EIU Freezing Rain: ____ Southern IL Rain: ____ Snowfall totals across the Chicagoland ranged from 15 inches to over 2 feet during this blizzard. If we assumed that on average, the metro area was covered in 19 inches of snow, what percentage of the volume of the Grand Canyon would this amount of snow fill? Show all of your work! Area of Chicago and surrounding suburbs: 10, 857 miles^2 Average depth of the snow over Chicago and surrounding suburbs: 19 inches Volume of the Grand Canyon: 4.166*10^12 meters^3Explanation / Answer
Answer- Sounding at Chicage blizzard, U of I sleet, EIU of Freezing rain and Southern El rain are following
Temperature
Chicage blizzard
Temperature
U of I sleet
Temperature
EIU of Freezing rain
Temperature
Southern El rain
given - area of chilago and near by suburbs is - 10,857 miles2 = 17472648 m2
depth of inches of snow in chicago and surrounding suburbs - 19 inches = 0.4826m
volume of snow covered in chicago and surrounding suburbs = 17472648*0.4826= 8432299.9m3
volume of grand canyon is 4.166* 1012 m2
if depth of snow in grand canyon is 19 inches or 0.4826m
then the volume of snow in grand canyon will be = 4.166* 1012 * 0.4826 = 2.010*1012 m3
