降水量，通常被称为降雨量，是量度以任何形式到达地面的降水的多少，不论是雨、冰雹或雪。整个美国的平均每年降水量为36吋。然而，应该理解的是，1英尺的降雪不等于1英尺的降水量。计算降雪的降水量的通用程式是38吋降雪等于1吋降水量。例如在纽约州，全年录得76吋的积雪会被记录为只有2吋降水量。全年录得40吋的降雨量会被记录为40吋降水量。全年录得的总降水量将是42吋。

原文如下：
Precipitation, commonly referred to as rainfall, is a measure of the quantity of water in the form of either rain, hail, or snow which reaches the ground. The average annual precipitation over the whole of the United States is thirty-six inches. It should be understood however, that a foot of snow is not equal to a foot of precipitation. A general formula for computing the precipitation of snowfall is that thirty-eight inches of snow is equal to one inch of precipitation. In New York State, for example, seventy-six inches of snow in one year would be recorded as only two inches of precipitation. The total annual precipitation forty inches of rain would be recorded as forty inches of precipitation. The total annual precipitation would be recorded as forty-two inches.

precipitation' 也就是我们一般说的降雨量 ，是一种用来测量降雪降雨量的指标。 美国的年均降雨量是36英尺。但是我们应该知道一英尺的雪和雨是不相等的，他们之间换算的公式是38英尺的降雪等于一英尺的降雨。例如 在纽约 一年76影驰的降雪只能被当做2英尺降雨.每年总降雨量40英尺.总降雨40英尺会被记作40英尺降雨量.每年总降雨量会被记作42英尺.......有点乱啊···追问
