“…(2016, 2021) related the inter‐model spread in future Southwest wintertime precipitation trends to the inter‐model spread in the climatological stationary wave field and its response to climate change. Finally, Schmidt and Grise (2021) found that, in CMIP6 models, the largest 21st century wintertime precipitation trends in the Southwest were favored by model simulations with both (a) trends toward an El Niño‐like state in the tropical Pacific and (b) trends toward the negative phase of the East Pacific teleconnection pattern, which is similar to the California Precipitation Mode (Chen et al., 2021).…”

“…To illustrate how consistency matters, Grotjahn and Faure (2008) showed composite averages for extreme precipitation in Sacramento, California which includes a strong atmospheric ridge over western Alaska and a cutoff low off the northern California coast. Locally, all such extreme precipitation events there have that low (Chen et al, 2021; Grotjahn & Faure, 2008). Although both the ridge and the trough are highly significant, only the trough occurs with high consistency.…”

In climate science and applications, the term "metric" is used to describe the distillation of complex, multifaceted evaluations to summarize the overall quality of a model simulation, or other data product, and/or as a means to quantify some response to climate change. Metrics provide insights into the fidelity of processes and outcomes from climate models and can assist with both differentiating models' representation of variables or processes and informing whether models are "fit for purpose." Metrics can also provide a valuable reference point for co-production of knowledge between climate scientists and climate impact practitioners. Although continued metric developments enable model developers to better understand the impacts of decisions made in the model design process, metrics also have implications for the characterization of uncertainty and facilitating analyses of underlying physical processes. As a result, comprehensive evaluation with multiple metrics enhances usability of climate information by both scientific and stakeholder communities. This paper presents examples of insights gained from the development and appropriate use of metrics, and provides examples of how metrics can be used to engage with stakeholders and inform decision-making.
