ABSTRACT. Synoptic Conditions Generating Important Snowfalls and Their Relation with Avalanches in 2015-2016 Winter. The paper presents and analyzes variations in weather conditions, meteorological and nivological (snow related) parameters that favored avalanches triggering in Bucegi and Făgăraş Mountains during 2015-2016 winter, an area monitored by the program for snow and avalanches within Romanian National Meteorological Administration. Analyzed parameters are measured on daily observations and weekly measurements, at Bâlea-Lac, Vârful Omu, Sinaia and Predeal meteorological stations and during the campaigns of measurements made within project Snowball, which aims to inventory cases of avalanches previously known in our country and the favorable conditions, for a better avalanche risk estimation and to reduce their effects on the environment and people. Data from daily observations and NCEP reanalysis ground level pressure maps, absolute topography and temperature maps at 500 hPa were used, from http://www.wetter3.de.
