Abstract:
With the daily observational data at 93 meteorological stations in Heilongjiang, Jilin, Liaoning and eastern Inner Mongolia in the past 50 years (1958-2007), the spatial and temporal distribution characteristics of heavy snowfall in Northeast China are analyzed. The results show as follows: First, heavy snowfall in this area is obviously distributed by seasons, and most of the heavy snowfall are in spring (March-April) and fall (October-November). Second, heavy snowfall in this area is also obviously distributed by regions, and most of the heavy snowfall are in southeastern Changbai Mountains, southern Liaodong Peninsula and northwestern Da Hinggan Mountains. Third, the yearly total precipitation of heavy snowfall in the past nearly 50 years almost didn’t change, but the heavy snowfall precipitation of spring (fall) in Northeast China tends to be more (less).
