Part #2: Liquid to Snow Ratio Many of you have probably heard that an inch of rain would make a foot of snow if it were cold enough to snow This statement is referring to a term/phrase in meteorology that is used during winter called the "Liquid to Snow Ratio". When weather models predict the total amount of precipitation, it is always done in "inches of liquid equivalent". In other words, the models predict the total amount of water in liquid form that can be pre the atmosphere for a given weather event. Meteorologists turn these values into snowfall totals by annl "Liquid to Snow Ratio". The most common ratio is 1:10 but the colder the air is when it snows, the hi ying a Imagine a winter storm was heading for Champaign, IL and the forecast models predicted we would of liquid equivalent precipitation. Use the liquid to snow ratios for e the total snow depth in inches. Write your answer in the space to the right of each scenario get 1.15 inches ach temperature range given below to calculate Scenario #1 : The temperature will be 30°F and the ratio is 1.7 Scenario #2: The temperature will be 24 and the ratio is 1:10 Scenario #3 : The temperature will be l 1°F and the ratio is 1 : 12. Scenario #4: The temperature will be 3°F and the ratio is 1 : 18.

Explanation / Answer

Liquid to snow ratio is the total amount of water in liquid precipitated in rain which is used in making snowfall. The average liquid to snow ratio is 1:10 which means 1 inch of rainfall will produce 10 inch of snow. 1.15 inches liquid equivalent precipitation is given

1) ratio is 1:7 , therefore snow in inches = 7×1.15=8.05 inches

2) ratio is 1:10, therefore snow in inches = 10×1.15= 11.5 inches

3) ratio is 1:12 , therefore snow inches = 1.15×12= 13.8 inches

4) ratio is 1:18 , therefore snow inches = 1.15×18= 20.7 inches
