hungeobull-7396	Kis, Anna; Pongrácz, Rita	The role of temperature and the NAO index in the changing snow-related variables in European regions in the period 1900‒2010	2021	14	.pdf	application/pdf	6701	329	57	Due to climate change, winter tourism faces chal- lenges in many regions as snow period and snow depth are likely to reduce in the future. Bednorz, E. (2004) calculated the correlation coefficients between snow cover in Eastern Europe and the NAO index and found a strong correlation in winter, which is statisti- cally significant West of 30° E. Henderson, G.R. and Leathers, D.J. (2010) also concluded that there is a strong association (r = ‒0.591) between large snow-covered areas and the negative phase of the NAO in Europe, based on NOAA (National Oceanic and Atmospheric Administration) satellite products.	cache/hungeobull-7396.pdf	txt/hungeobull-7396.txt
