**Please answer both parts (a) and (b). Thank you!**
When rain falls on a snowpack, the snow is sometimes observed to melt more quickly than it would have if there had been no rain. The apparently obvious explanation is that the rain melts the snow. (a) To check the validity of this, calculate how much rain (in inches) would be needed to melt one inch (in liquid water equivalent) of snow. Assume that the temperature of rain is 2°C and that of snow is 0°C. (b) You may think that, produce an inch of rain. How warm would that rain have to be in order to melt one inch in liquid water equivalent) of snow?Explanation / Answer
A. Since the temperature is 2°C , we can assume the snow ratio as 40:1
For 2 inches of snow,
2x1/40 = 0.05 inches of rain.
B. If the storm is very strong, we can assume high temperature as 50°C, then snow ratio changes to 5:1
Then for 1 inch of snow,
1X1/5 = 0.2 inches of rain is enough.
