在这项研究中，模型推导的降雪从2006年到2100年进行了分析，调查存在的湖诱导（LI）降雪信号的背风湖伊利和安大略。耦合模式相互比较项目第5阶段使用了7个完全耦合的全球气候模式的输出。针对两种代表性的浓度路径（RCP）情景，对整个研究区域和定义的LI雪带的降雪趋势进行了季节性检查。术语湖泊诱导用于包括两个湖泊效应过程，沿着湖泊增强的雪。除了降雪，物理机制与这些趋势，如表面温度和雪总降水量的比例，进行检查。
In this study, an analysis of model‐derived snowfall from 2006 to 2100 is conducted, investigating the presence of a lake‐induced (LI) snowfall signal to the lee of Lakes Erie and Ontario. Output from seven fully coupled global climate models is used from phase 5 of the Coupled Model Intercomparison Project. Snowfall trends over the entire study area, and in the defined LI snowbelt, are examined seasonally for two representative concentration pathway (RCP) scenarios. The term lake‐induced is used to encompass both lake effect processes, along with lake‐enhanced snow. In addition to snowfall, physical mechanisms associated with these trends, such as surface temperatures and snow to total precipitation ratios, are examined.
