TY - Generic T1 - Estimating dates of the snow accumulation season T2 - 56th Annual Western Snow Conference Y1 - 1988 A1 - Tabler, R.D. KW - Air temperatures, Precipitation, Snow accumulation, Snow transport AB - It is often necessary to estimate the average snow accumulation season, defined as extending from the first persistent snowfall to the time of peak water-equivalent, as a first step in estimating average winter precipitation. The snow accumulation season is shown to be delimited by dates when air temperatures reach 0 degrees C, as computed from mean monthly temperatures. For locations lacking climatological records, estimates can be derived from multiple regressions relating 0 degrees C dates at surrounding stations to elevation, latitude, and longitude. Regression equations are presented for all states in the snow belt, and a general equation indicates that dates of the snow accumulation season vary at the average rate of 2.5 days per 100 meters of altitude, 5.5 days per degree of latitude, and 1 day per degree of longitude, earlier northward, eastward, and upward in the fall, and the reverse in the spring.
