Abstract:The article uses daily precipitation and temperature data from the northern and western districts of Changbaishan for the winter months of November to March from 2010 to 2020,as well as Micaps real-time data,a statistical analysis was conducted on the spatiotemporal distribution patterns of 25 precipitation events classified as heavy to blizzard-level and above.The study explored weather characteristics such as the configuration of high and low-altitude systems,water vapor sources,frontal intensity,and precipitation phase.The results indicate that,in terms of temporal distribution,the highest number of heavy to blizzard-level precipitation days occurs in late autumn and early spring (November and March),followed by December and February,with no such events in January.In terms of spatial distribution,the western district experiences more days and higher average snowfall compared to the northern district.Precipitation intensity is closely related to the influencing system,water vapor source,and frontal intensity.During the transition season between rain and snow,the intensity of cold and warm advection,as well as the start time of precipitation,can be used as key indicators to determine the precipitation phase.
