    Assessment of Climate Change Impacts in the Midwest and Great Lakes Region Using Multi-Scale Modeling Strategies

    Abstract

    The effects of climate change on the Midwest and Great Lakes Region are expected to include extreme changes in temperature (T), increasing precipitation (P) in winter and spring, and (based on observations) increasingly intense convective storms in warm season. Changes in the Great Lakes themselves (such as loss of ice cover, and extended stratification) combined with changes in global circulation affecting arctic air outbreaks may result in altered lake-effect snow regimes, or other effects on extreme weather. Hydrologic extremes (e.g. floods and droughts) are hypothesized to intensify due to increasing winter/spring P and T and decreasing snow/rain ratios. In urban settings, changes in climate combined with changes in urban heat island effects are expected to affect both extreme heat and humidity, and urban stormwater impacts. To quantify these kinds of regionally specific impacts in greater detail, integrated simulation models at a range of spatial and temporal scales are needed. In this talk we cover two specific kinds of modeling frameworks. The first is based on statistically downscaled global climate models (GCMs), which are then one-way coupled with off-line hydrology models (e.g. VIC, SWAT). The second is based on dynamical downscaling using high-resolution Weather and Research Forecasting (WRF) climate models. These tools range in scale from 12-km to 4-km resolution implemented over the entire region, to ultra-high resolutions (1-km to 300-m) models developed in support of detailed urban studies. Each of these approaches has its unique advantages.
    The primary advantage of statistical downscaling is that many GCM projections can be downscaled to explicitly quantify uncertainty. Key findings for the Midwest include extreme T changes (up to 10 °C by 2100 for the RCP8.5 scenarios), and widespread impacts to seasonal streamflow and river flooding. Loss of snow cover and decreases in the snow/rain ratio will likely affect water quality in winter in agricultural settings and (without adaptation) increase nutrient pollution in the Great Lakes. The extreme nature of T increases, coupled with a longer growing season, raises many important questions about the future of agriculture in the Midwest, and changes in natural vegetation cover. Effects on northern forests will be particularly important.
    The primary advantage of using dynamical downscaling is that fine-scale physical processes not captured by GCMs can be captured. A few initial studies have attempted to quantify changes in convective storm intensity, but much more work is needed in this area to better quantify local impacts (e.g. for specific urban centers). Impacts to extreme heat and humidity in urban settings intensify under climate change, and fine-scale sensitivity experiments show that attempts to adapt to increased urban heating using energy saving green or cool roofs may reduce vertical and horizontal air circulation and adversely impact air quality. In future research, there is a need to dynamically couple WRF to the Great Lakes to better simulate and analyze effects associated with the coupled system. Such impacts include changes in vertical mixing over and in the Great Lakes, changes in evaporation and precipitation over the lakes themselves, changing lake-effect snow, and extreme wind and waves in near shore areas.

    Bio

    Alan F. Hamlet
    Dr. Alan F. Hamlet is an Assistant Professor in Civil and Environmental Engineering and Earth Sciences at the University of Notre Dame. He is a specialist in the integrated computer modeling of climate, hydrologic systems, water resources systems, and ecosystems. These activities include construction of historical hydrometeorological data sets, statistical and dynamic downscaling of climate model output, large- and small-scale hydrologic modeling of surface and groundwater systems, analysis of hydrologic extremes (floods, droughts), water resources modeling (simulation and optimization of reservoir operations), and ecosystem modeling of oceans, rivers, estuaries, wetlands, and lakes. Dr. Hamlet has also participated in modeling studies of regional energy systems, agricultural systems, as well as urban heat-related deaths stemming from changing temperature and humidity regimes. The tools employed in these diverse research activities can be readily applied at local- to global-scales to suit a wide range of applications, and Dr. Hamlet has been involved extensively in integrated modeling studies in North America (e.g. in the western, central, and southeastern U.S.) as well as at the global scale.

    Ashish Sharma
    Ashish Sharma is currently working as a Research Assistant Professor at the Department of Civil & Environmental Engineering & Earth Sciences and the Environmental Change Initiative at the University of Notre Dame. He completed his Ph.D. in the year 2012 at Arizona State University in the broad area of environmental fluid dynamics related to atmospheric sciences and engineering applications. During his Ph.D., Dr. Sharma focused on large-scale climate studying semi-arid regions across the world. Dr. Sharma’s current research interests intersect science, engineering, and social sciences with primary focus in atmospheric sciences. He studies land/ocean-atmosphere interactions at a range of spatial scales (regional to local) that are relevant to the management of human and natural systems. He develops and evaluates approaches to sustainable climate actions, understand their interrelationships and scaling properties that affect adoption and implementation by neighborhood and regional scales in natural, agricultural and urban environments. Dr. Sharma is currently funded by US Environmental Protection Agency (EPA) to study the impact of cover crops to prevent nutrient runoff and promote climate resiliency in Great Lakes watersheds. He also collaborates with cities and institutions to work on environmental issues related to heat, fog, air quality, and high impact weather.
