“…Other global-scale processes and feedbacks in the climate system are, of course, no less important. The impact of the NAO/AO is also dependent on the QBO: the impact during the eastern phase of the QBO is felt in larger territories and reaches higher altitudes, whereas during the western phase of the QBO, the impact signal is more local (Kuroda 2007;Akstinas & Bukantis, 2015). NAO fluctuations and the long-term anomalies thereof lead to conditions favourable to the development of long-term weather anomalies within the Baltic Sea Region (Bukantis & Bartkeviciene, 2005;Mickevičius & Bukantis, 2013).…”
