STATISTICAL CORRELATION BETWEEN ANNUAL PRECIPITATION OF MAXIMUM PRECIPITATION HEIGHT AND FOOTHILL IN THE UNITED STATES

In the study of precipitation distribution in the mountains in the UnitedStates, we can see from normal precipitation that there is maximumprecipitation height on the slopes of higher than 5,000 ft. commonly.Using yearly precipitation data from 1951 to 1980, we survey interannualvariation of maximum precipitation height and discover that yearlymaximum precipitation height is very stable and it almost does not changefrom year to year on the windward slopes, but its annual precipitation
