Relationship between cold season air temperature in the Baltic sea region and the Arctic sea ice extent

The variability of the atmospheric circulation described by AO and NAO indices has a significant impact on fluctuations climate parameters in Baltic Sea region. Many research show, that decline Arctic ice extent increases likelihood negative phases Oscillation (AO) North Atlantic (NAO) winter, future could lead to more frequent relatively cold weather events during winter months This is important for understanding possible teleconnections between (AO NAO). In addition, this helps better understand dynamics region air temperature, as well temperature A statistically decrease increase have been determined. obtained results show expansion January-February with delay one month determines values (correlation coefficients vary from 0.32 0.55). means if decreases months, are likely become well. However, correlations not very strong, insufficient confirm hypothesis impacts requires further research. strong correlation AO/NAO established. December-March greatly influenced phases.
