Annual Extreme Values of Snowfall Meteorological Data in Yantai Region

The annual extreme values of snowfall are inferred based on daily temperature (highest, lowest, and average) and precipitation data obtained from the National Greenhouse Data System and the National Environmental Information Center (NCEI) over the past 39 years. The data is collected from two meteorological stations, Yantai and Yantai North. The snowfall rate and depth are calculated based on the snowfall water content ratio (SLR=1.3cm/mm), arranged from small to large according to the snowfall depth, and the cumulative distribution frequency is calculated using the Cunnane criterion.
