“…Such a situation is related to the development of the ice cover that appears faster in the east, and the difference between its persistence between the eastern and western part of the study area exceeding 30 days [43]. The ice cover is one of components affecting the climatic conditions of lakes of the moderate zone [44]. In reference to the situation presented above, due to the existing ice cover, lakes in the eastern part in December responded to atmospheric factors differently than those still free from ice.…”

Abstract:The objective of the paper was the determination of the effect of teleconnection patterns (North Atlantic Oscillation (NAO), Arctic Oscillation (AO), East Atlantic pattern (EA), East Atlantic/Western Russia (EAWR), and Scandinavian pattern (SCAND)) on changes in air and water temperature in Polish lakes. Correlations of circulation indices with air and lake water temperature were analysed in the monthly cycle. Deviations of values of such components in different phases of the analysed atmospheric circulations types from mean average from the years 1971 to 2015 were also determined. The research showed a variable effect of the atmospheric circulations types. The strongest effect on water temperature was observed in winter, when AO and NAO circulation showed particularly evident influence. Deviations of water temperature from mean values from the analysed multi-annual period generally oscillated around 1.0 • C, reaching a maximum value of 1.4 • C. The presented research shows the complexity of processes determining changes in lake water temperature, the course of which depends on many factors with both regional (e.g., ice cover on lakes) and local range (conditions of water exchange, human pressure).

“…However, the ice regime of Lake Superior and the other Laurentian Great Lakes is unlike that of other large northern lakes (e.g., Great Slave Lake) or smaller lakes at the same latitude (Mishra et al 2011). Lake Superior rarely freezes completely, and the ice in any given location, especially offshore, is transient over time.…”

Feedbacks between ice extent and evaporation have long been suspected to be important for Lake Superior evaporation because it is during autumn and winter when latent heat fluxes are highest. Recent direct measurements of evaporation made at the Stannard Rock Lighthouse have provided new information on the physical controls on Lake Superior evaporation, in particular that evaporation can react within hours to days to a change in synoptic conditions. However, the large heat capacity of the lake creates a strong seasonal cycle of energy storage and release. There is a complex interaction among heat storage, evaporation, and ice cover that is highly dependent on atmospheric conditions in the spring and autumn ''shoulder seasons.'' Small changes in conditions in November and March caused by synoptic-scale events can have profound impacts on annual evaporation, the extent of ice cover, and the length of the ice-covered period. Early winter air temperatures in November and December dictate the nature of ice formation and much of the winter evaporative flux. Decreased ice cover, by itself, does not necessarily lead to enhanced annual evaporation losses. Rather, a combination of low ice cover and warm spring air temperatures, leading to an early breakup, can significantly lengthen the next evaporation season and cause greater cumulative water loss the subsequent year. The influence of individual synoptic events on annual evaporation is notable enough that the research community should ensure that their role is properly captured in numerical models to provide sound predictions of future Laurentian Great Lakes evaporation regimes.

“…Responses during the cold season may in turn influence lake conditions in other Global and Planetary Change 76 (2011) 166-185 seasons, such as the significant increase in lake surface water temperatures that has been observed across the United States (e.g. Coats et al, 2006;Schneider et al, 2009;Mishra et al, 2011). Austin and Colman (2007) reported that open water temperatures of Lake Superior have increased by 3.5°C with a 25 day increase in the length of the stratified season during the last century.…”
