“…The decadal megadroughts in the history had significant societal and economic consequences, which influenced the historical evolutions (Cook et al, 2010, 2015a; 2015b; Zheng et al, 2014). In addition, the risks of decadal megadroughts along with other extreme events are likely to increase in the future, because of the global temperature increases (Ning & Qian, 2009; Ning and Bradley, 2015; Ning et al, 2015; Cook et al, 2015a; 2015b; Ault et al, 2016; Chen et al, 2020a; 2020b; 2020c). Therefore, improved understanding on mechanisms of decadal megadroughts is critical to the future predictions of decadal megadroughts and also the sustainable societal and economic developments.…”

In this study, simulations of 13 all‐forcing experiments from the Community Earth System Model Last Millennium Ensemble (CESM‐LME) archive were used to investigate the different spatiotemporal characteristics and corresponding mechanisms of the decadal megadroughts over the eastern China during two typical periods in the past millennium, that is, Medieval Climate Anomaly (MCA) and Little Ice Age (LIA). The results show that there is no significant difference in either megadrought intensity or duration between the MCA and LIA, but there are significant differences in the megadrought frequencies. The frequency of megadroughts during the MCA is 1.44 times/hundred years, compared with 1.69 times/hundred years in LIA. Results from solar only sensitivity experiments and volcanic only sensitivity experiments show that this difference is mainly induced by the solar radiation. The mechanism analyses show that a spatial pattern of sea surface temperature anomalies (SSTA) resembling the positive Pacific Decadal Oscillation (PDO)‐like pattern have occurred simultaneously with the megadroughts during both the MCA and LIA. While, the megadroughts in MCA are strongly correlated with the strong PDO‐like SSTA patterns, and the megadroughts in LIA are strongly correlated with the weak PDO‐like SSTA patterns. In addition, the anomalous sea level pressure (SLP) field and wind field associate with the megadroughts during the MCA and LIA are consistent with the strengths of SSTA, with significant larger SLP and wind anomalies during the MCA than those during the LIA. Therefore, it can be concluded that the responses of the large‐scale atmospheric circulation patterns to SSTA are similar during these two typical periods, and the difference in the megadrought frequencies is due to the nonlinear response of the precipitation variability to the large‐scale atmospheric circulation patterns.

System-of-systems approaches for integrated assessments have become prevalent in recent years. Such approaches integrate a variety of models from different disciplines and modeling paradigms to represent a socio-environmental (or social-ecological) system aiming to holistically inform policy and decision-making processes. Central to the system-of-systems approaches is the representation of systems in a multi-tier framework with nested scales. Current modeling paradigms, however, have disciplinary-specific lineage, leading to inconsistencies in the conceptualization and integration of socio-environmental systems. In this paper, a multidisciplinary team of researchers, from engineering, natural and social sciences, have come together to detail socio-technical practices and challenges that arise in the consideration of scale throughout the socio-environmental modeling process. We identify key paths forward, focused on explicit consideration of scale and uncertainty, strengthening interdisciplinary communication, and improvement of the documentation process. We call for a grand vision (and commensurate funding) for holistic system-of-systems research that engages researchers, stakeholders, and policy makers in a multi-tiered process for the co-creation of knowledge and solutions to major socio-environmental problems.

Design and development of a web-based EPANET model catalogue and execution environment

Within the field of environmental and hydrologic modelling, there is a growing recognition of the scientific and educational value of sharing both model programs (i.e. the codes that formulate a model) and model instances (i.e. specific input files and model parameterizations). Indeed, numerous cyberinfrastructure tools have been created in recent years to simplify linking, executing, and sharing models. Multiple challenges hinder the adoption of such systems by modelling communities. These can include technological barriers such as installing and managing software and internet systems as well as social barriers such as a culture of not sharing models due to concerns over private or otherwise proprietary information. In some cases, model-sharing platforms are not easily replicated or implemented to fit the needs of a specific modelling community. This paper presents the design and implementation of a model-sharing repository and a modelviewing application, specifically for the EPANET modelling community -the pattern and structure of which could be easily adopted by any modelling community -using existing open source cyberinfrastructure. We used HydroShare as the backend data store for the EPANET model program, model instances, and metadata, and we used the rapid app development capabilities of Tethys Platform framework to create a web-based front-end for the repository and viewer. Results of this experimental work include a functional model repository based on less than 700 lines of code and a light-weight model viewer application that encompasses nearly 100% of the legacy EPANET desktop GUI's functionality.
