Synchrony in relationships between the North Atlantic Oscillation and water chemistry among Sweden’s largest lakes
The North Atlantic Oscillation (NAO) is commonly presented as an easy and reliable index that can be used to study climatic effects on aquatic ecosystems. Here, the NAO winter index (NAOW) was applied to determine effects of winter climate changes on 13 water chemical variables measured monthly at 1...
