ABSTRACT

The study presents changes in the elements of the hydrological regime of Lake Hańcza in the period 1960–2019, including water temperature, ice cover characteristics and water level. It was determined that statistically significant changes resulted in an increase in water temperature (0.11°C·dec⁻¹), a decrease in maximum ice thickness (5 cm·dec⁻¹) and an increase in water levels (6.7 cm·dec⁻¹). Changes in water temperature and ice cover in the analysed case are different from those in other lakes of the region. As the tests conducted in this study and in previous research have shown, the lake has resisted global warming for a relatively long time, and the change in thermal conditions occurred a decade later than in other lakes in this part of Europe. The analysed case leads to the conclusion that the morphometric features of lakes significantly modify the influence of overriding factors, such as climate conditions.

摘要

该研究介绍了 1960 年至 2019 年期间汉察湖水文状况要素的变化，包括水温、冰盖特征和水位。经确定，统计上的显着变化导致水温升高 (0.11°C·dec ^-1 )、最大冰厚度减小 (5 cm·dec ^-1 ) 和水位升高 (6.7 cm·dec ^-1 ) ^{。 1}）。分析案例中的水温和冰盖变化与该地区其他湖泊不同。正如本研究和之前的研究所进行的测试表明，该湖抵御全球变暖的时间相对较长，热条件的变化比欧洲这一地区的其他湖泊晚了十年。分析案例得出的结论是，湖泊的形态特征显着改变了气候条件等首要因素的影响。
