对北方爱达荷州的两种针叶树幼树的雪截留量的研究表明，累积的雪截留量遵循经典的自生增长规律，即
其中Is是拦截存储量，S是树的拦截存储容量，e是自然对数的底，k是表示拦截存储率的常数，P是累积降雪量，并且P0是最快速存储时的累积降雪量（即，S形曲线的拐点）。拦截存储符合法律在五个风暴中，开始降雪，而树木是光秃秃的，在两个风暴中，降雪，而以前的风暴雪坚持在树上。有几次小风暴的数据不足以确定适当的常数，但检查表明没有严重偏离一般规律。
Study of interception storage of snow by two species of sapling conifers in northern Idaho revealed that cumulative snow catch follows the classical law of autocatakinetic growth, or
where Is, is interception storage, S is the interception storage capacity of the tree, e is the base of the natural logarithm, k is a constant expressing the rate of interception storage, P is accumulated snowfall, and P0 is accumulated snowfall at the time of most rapid storage (i.e., the point of inflection of the sigmoid curve). Interception storage conformed to the law in five storms in which snowfall began while the trees were bare, and in two storms in which snow fell while snow from previous storms persisted on the trees. Several small storms yielded insufficient data to define the appropriate constants, but inspection indicated no serious deviation from the general law.
