摘      要：High montain lakes are regarded as sensitive indicators of environmental changes in local and global *** recent years,climate change has considerablely influenced the timing of ice phenomena in these *** objective of the paper is an investigation of long-term changes and periodicity of ice phenomena in high mountain Lake Morskie Oko(1392.8 m a.s.l.)located in the Tatra *** the period *** study employed the Lomb-Scargle periodogram,linear regression modelling for temporal trends,correlation analysis,parameters of variability,and flashiness *** of the duration of ice phenomena(~5.4 y)and ice cover on the lake(~13.5 y)was observed,although both are statistically *** cover duration has been interrupted several times by winter thaws after 1996 whereas no such events had been reported *** trend towards a delayed appearance of ice phenomena reaches 4.0 d·decade^(-1)(p0.001).The observed trend towards an earlier ice phenomena disappearance reaches 5.1 d·decade^(-1)(p0.001).It results in a decline of the number of days with ice phenomena on Lake Morskie Oko at a rate of 9.0 d·decade^(-1)(p0.001).The duration of ice cover on Lake Morskie Oko has been decreasing at a rate of 10.4 d·decade^(-1).It is attributed to later freezeup(3.9 d·decade^(-1),p0.001)and earlier ice break-up(5.6 d·decade^(-1),p0.001).An increasing trend of average annual air temperature(0.4°C·decade^(-1),p0.001)in the period 1971-2020 is observed.A statistically significant correlation is recorded between ice phenomena and ice cover(beginning,end,duration),average annual air temperature,average air temperature of three summer months(June,July,August),and average air temperature of the six months period from June to *** air temperature induces growing heat resources accumulated in the lake water in the summer and autumn seasons,potentially causing later initiation of ice phenomena in the *** is no statistically significant r
