Atmospheric circulation conditions and snowy weather in the Southern Alps: Case of the Isola 2000 weather station
This paper focuses on the relationship between atmospheric circulation and solid precipitation (SP) happening in the weather station of Isola 2000. Located in the French department of the Alpes-Maritimes at an altitude of 1912 m, it has the oldest series of daily SP and snow depth (SD) observations...
