| Abstract | Atmospheric circulation patterns, impact of climate change and reindeer demographic changes in northern Scandinavia. To better understand the climate system in Lapland impacts of climate change on traditional reinde er husbandry, we crossed time series of atmospheric cir culation indexes with climate data from nearby distr icts where demographic changes of herds are informed. For 1950 -2013, increasing occurrence of the winter NAO is obs erved from 1981 at the expense of SCAND. From 1967 to 2013, the overall trend is warming with increasing occurrence o f p sitive anomalies of AO and NAO in winter and decreasing in c old days and snow depth in autumn beneficial on rein deer. Population fluctuations of wild reindeer in Svalbard are positively correlated to the Arctic Oscillatio n. |
