Question

A major snowstorm occurred in a city in northern New Jersey. Three volunteer weather observers measured the snowfall. Observer #1 measured the depth of newly fallen snow every hour. At the end of the storm, Observer #1 added up the measurements and came up with a total of 12 inches of new snow. Observer #2 measured the depth of new snow twice: once in the middle of the storm and once at the end, and came up with a total snowfall of 10 inches. Observer #3 measured the new snowfall only once, after the storm had stopped, and reported 8.4 inches. Which of the three observers do you feel has the correct snowfall total? List at least five possible reasons why the snowfall totals were different.

Explanation / Answer

Observer 3 may measure the correct depth of water of the snow. the snow measurments are somewhat typical as the natural effects such as melting air and drifting may chagne the depth snow

measurements will differ due to :

1. none of the observer followed the usual technique

2. During storms, it is difficult. Hence Ist and IInd observer may not be able to get the readings accurately

3. The first observer measures the first falls and adds upit at the end but the formation of overlying new snow reduces the thickness of old lower snow flake by its weight

4. second oberver measured the snow fall twice as in the middle and at the end

they actually take 6 hrs in a day

5. third observer measured the snow deoth at the end of the fall. this prodedure can give the existing depth at the time
