通信彼得A. pasiv@conncoll.edu气候变化在许多方面影响着淡水湖，包括热结构、稳定性、冰盖、年度混合制度和生长季节长度的变化，所有这些都影响着生态系统的结构和功能。我们研究的影响气候变量，特别是风速，在Candlewood湖（康涅狄格州，美国）的三个地点的水温和热分层。在1985年到2015年间。尽管在31年的时间内缺乏与时间相关的区域气温或降水趋势，但春季和夏季的风速显著下降，在研究期间平均下降31%。尽管观察到7月平均临水温度（22.8-28.2°C）变化很大，但没有随时间变化的趋势。与此相反，一个显着的冷却趋势，记录了与风速下降高度相关的低层。风速的减小也与最大RTRM值估计的温跃层强度的增加有关。尽管缺乏一个变暖的趋势，在地表沃茨在整个研究期间，夏季热稳定性的强度估计使用总RTRM分数是高度相关的epilimnetic温度。风速下降的潜在后果，一个冷却的温跃层，和一个更强的温跃层进行了讨论。
Correspondence Peter A. Siver Email: pasiv@conncoll.edu Climate change has affected freshwater lakes in many ways, including shifts in thermal structure, stability, ice cover, annual mixing regimes and length of the growing season, all of which impact ecosystem structure and function. We examine the impacts climate variables, especially wind speed, had on water temperature and thermal stratification at three sites in Candlewood Lake (Connecticut, U.S.A.) between 1985 and 2015. Despite the lack of regional time-related trends in air temperature or precipitation over the 31 year period, there was a significant decline in wind speed during spring and summer months, with a mean decline of 31% over the study period. Even though a wide range in mean July epilimnetic temperature (22.8–28.2°C) was observed, there was no trend over time. In contrast, a significant cooling trend was recorded for the hypolimnion that was highly correlated with the declining wind speed. Decreasing wind speed was also correlated with an increase in the strength of the thermocline estimated from maximum RTRM values. Despite the lack of a warming trend in surface waters over the entire study period, the strength of summer thermal stability estimated using total RTRM scores was highly correlated with epilimnetic temperature. The potential consequences of declining wind speed, a cooling hypolimnion, and a stronger thermocline are discussed.
