气候变化，特别是空气温度的升高，已被证明会影响湖泊的热动力学，气候变暖导致表面温度升高，分层增强，混合机制改变。研究较少的是大气静止对湖泊热动力学的影响，近几十年来观察到的近地面风速下降。在这里，我们使用一个湖泊模型来评估大气静止的影响，湖泊热动力学在北方半球。从1980年到2016年，由于大气静止，湖泊对变暖的热响应加速。湖面温度和热稳定性分别以0.33和0.38 °C/decade的速率变化，大气静止分别占计算变化的15%和27%。大气静止也导致了分层的延长，占计算变化的23%。我们的研究结果表明，大气静止影响湖泊的热响应变暖。
Climate change, in particular the increase in air temperature, has been shown to influence lake thermal dynamics, with climatic warming resulting in higher surface temperatures, stronger stratification, and altered mixing regimes. Less studied is the influence on lake thermal dynamics of atmospheric stilling, the decrease in near‐surface wind speed observed in recent decades. Here we use a lake model to assess the influence of atmospheric stilling, on lake thermal dynamics across the Northern Hemisphere. From 1980 to 2016, lake thermal responses to warming have accelerated as a result of atmospheric stilling. Lake surface temperatures and thermal stability have changed at respective rates of 0.33 and 0.38 °C/decade, with atmospheric stilling contributing 15% and 27% of the calculated changes, respectively. Atmospheric stilling also resulted in a lengthening of stratification, contributing 23% of the calculated changes. Our results demonstrate that atmospheric stilling has influenced lake thermal responses to warming.
