“…In the Coordinated Regional Climate Downscaling Experiment—North American project, some RCMs (e.g., Canadian regional climate model, Scinocca et al., 2016) couple with a one‐dimensional lake model called the Fresh Water Lake model (Mironov et al., 2004), which can provide improved results compared to the interpolation approach (Gula & Peltier, 2012; Xiao et al., 2018). Other researchers have developed more complex coupled modeling systems using three‐dimensional hydrodynamic lake models that were shown to be even more accurate than the RCMs with one‐dimensional lake models (Sun et al., 2020; Xue et al., 2017).…”

Impacts of Lake Surface Temperature on the Summer Climate Over the Great Lakes Region

et al. 2022

The total surface area of the Great Lakes is over 94,250 miles 2 . Consisting of five large lakes, they contain over one fifth of the world's total surface fresh water, with depths of up to 400 m (EPA, 2020). The Great Lakes substantially influence the regional weather and climate via their effects on the atmospheric energy and water budget; open water typically has greater thermal conductance, lower albedo, and lower roughness compared to soil or vegetated surfaces (Notaro et al.,2013;Scott & Huff, 1996). The large thermal inertia of the lakes leads to a reduction in annual and diurnal temperature ranges across the Great Lakes Basin (Harris & Kotamarthi, 2005;Notaro et al., 2013). Mean minimum temperatures in the region are warmer during all seasons and over all five lakes, while maximum temperatures are cooler during spring and summer (Scott & Huff, 1996). Lake thermal impacts and associated evaporation have a strong influence on regional precipitation patterns. While many studies have investigated the impact of lake surface temperature (LST) on the cold-season precipitationwhich is primarily a direct product of warmth and moisture from the Great Lakes (e.g., lake-effect snow; Notaro et al., 2021; Shi & Xue, 2019)-the impact of LST on summer precipitation has only rarely been studied. During early summer, the lake surface is still relatively cool compared to the atmosphere, resulting in condensation on the lake surface and a stable boundary layer that deters over-lake convective processes (Miner & Fritsch, 1997;Workoff et al., 2012). Due to the temperature differences over lake and inland, lake breeze can cause air to rise inland and increases the likelihood of over-land precipitation (Schulkowski, 2020). During late summer, while the land cools and the lakes remain warm, the temperature differential between land and lake surface coupled with baroclinic waves (e.g., cold front and trough) and/or the Great Plains low-level jets can generate enhanced precipitation (Feng et al., 2016;Miner & Fritsch, 1997). Therefore, changes in summer LST could potentially affect its feedback to atmospheric stability and change the water and energy budget over the entire Great Lakes Region (GLR). The summer is an ideal time to evaluate the influence of LST on the lake surface-atmosphere

“…The University of Maryland makes significant contributions through six publications focused on precipitation and climate models. Although they do not mention the nexus approach, their findings are pivotal to assessing models that incorporate the effects of climate change in accounting for changing patterns of precipitation for agriculture and hydroelectric energy (Sun and Liang, 2020a , b ; Sun et al, 2020 ; Li et al, 2021 ). It is important to highlight that almost all publications from this are co-authored by researchers from their partner, Nanjing Agricultural University, which may result from a project governance policy developed by the U Maryland and Nanjing U team.…”

The challenges and consequences of climate change have brought together governments around the world to advance scientific knowledge and programmatic actions to develop mitigation strategies while promoting sustainable development. The United States and China—the countries with the highest science expenditures globally—have historically developed a range of joint international research collaborations. However, under the “America First” agenda put forth by the Trump Administration, bilateral diplomatic relations with China reached their highest confrontational peak. Under this scenario science diplomacy served as a catalyst to maintain scientific collaborations between both countries. In 2018, the US National Science Foundation and the China National Natural Science Foundation launched the InFEWS US-China program to promote collaborations to expand food, energy, and water nexus (FEW Nexus) research and applications. Over the past four years, 20 research projects have been awarded from the US side and 47 publications have been reported as research output. By carrying out a descriptive analysis of the InFEWS US-China research and scholarly outputs, we find evidence of the crucial role played by the Chinese scientific diaspora who led 65% of the projects awarded. We find that there is a generally good understanding of the interdependencies between FEW systems included in the project abstracts. However, in the InFEWS US-China scholarly outputs generated to date, there is a lack of usage of a clear FEW Nexus theoretical framework. Further research should address intentional policies that enhance the involvement of scientific diasporas in their home countries to better address climate, sustainability, and development challenges.

“…The widespread of the Great Lakes region has unavoidable influences on the atmospheric dynamics (Sun et al., 2020). Conversely, the Great Lakes hydrodynamics are majorly governed by the meteorological parameters and the rapid intervention of climate change.…”

“…Studies for the Great Lakes cover broad aspects of lake meteorology, circulation, biogeochemical cycle in a changing climate; however, a thorough analysis of lake dynamics for a long‐term climate projection is merely attempted. Meanwhile, investigations on the dynamics of lake circulation have been challenging for a long timescale and large spatial extent (Abraham et al., 2013; Sun et al., 2020). Key challenges to this issue can be (a) the uncertainty involved in hydrodynamic simulations due to the lack of high‐resolution atmospheric products, (b) the degree of complexity associated with climate change and lake geography, (c) insufficient knowledge of the lake’s three‐dimensional thermal profile, and (d) the diversity in episodic and regional (sector‐wide) lake hydrodynamics.…”

The Great Lakes, often described as inland freshwater seas (Sterner et al., 2017), potentially govern the regional weather and climatic processes (Changnon & Jones, 1972). The vast water body maintains a lower air temperature in the surrounding area in summer and vice versa in winter (Notaro et al., 2013;Scott & Huff, 1996). Over the past decades, the Great Lakes have been reportedly impacted by global warming and climate change (IPCC
