山区湖泊经历极端的年际气候变化以及快速变暖的气温，使它们成为了解湖泊气候响应的理想系统。积雪和水温在高山湖泊中高度相关，但我们缺乏对潜在机制的完整了解。受预测降雪量随未来气温升高而下降的影响，我们研究了表面热通量和湖泊变暖对加州内华达州塞拉利昂高海拔湖泊积雪、结冰和夏季天气模式变化的响应。封冻时间决定了湖泊暴露于太阳辐射的物候，是连接积雪和湖泊温度的主要机制。热损失通量（长波辐射、潜热和感热交换）的相对重要性在丰水年和干旱年之间存在差异。山区积雪和冰盖的减少将减少湖泊热响应的变化，并增加湖泊变暖对大气强迫的响应。
Mountain lakes experience extreme interannual climate variation as well as rapidly warming air temperatures, making them ideal systems to understand lake‐climate responses. Snowpack and water temperature are highly correlated in mountain lakes, but we lack a complete understanding of underlying mechanisms. Motivated by predicted declines in snowfall with future temperature increases, we investigated how surface heat fluxes and lake warming responded to variation in snowpack, ice‐off, and summer weather patterns in a high elevation lake in the Sierra Nevada, California. Ice‐off timing determined the phenology of lake exposure to solar radiation, and was the dominant mechanism linking snowpack to lake temperature. The relative importance of heat loss fluxes (longwave radiation, latent and sensible heat exchange) varied among wet and dry years. Declines in snowpack and ice cover in mountain systems will reduce variability in lake thermal responses and increase the responsiveness of lake warming to atmospheric forcing.
