Hazardous Heavy Snowfall Events in the Ural region (Russia) in 1981 - 2025

the dataset consist of 116 heavy snowfall reports (snowfall intensity ≥ 20 mm 12 h^-1), which have occurred in the Ural region in the period 1981 – 2025. They are associated with 56 different heavy snowfall events. Among them, there are 97 reports (48 events) of heavy snowfall and 19 reports (8 events) of heavy wet snow or snow mixed with rain (precipitation intensity ≥ 20 mm 12 h^-1). For each report, the date and time of occurrence and WMO ID of the weather station are shown (except for several weather stations which ceased observations in the 1990s). 12-h and 24-h accumulated snowfall, and wind gusts (if available) are given for each reports. In addition, they are classified into 5 types by the air mass origin according to the 72-h backward trajectories according to the NOAA HYSPLIT model. There are S type (southern advection from the Caspian or Aral Seas); SW type (southwestern advection from the Black or Mediterranean Seas), W type (western advection from the Baltic, North and Norwegian Seas); NW type (northwestern advection from the Barents Sea) and local type (when there is hard to identify the moisture source).
