    How Visual Design of Severe Weather Outlooks Can Affect Communication and Decision-Making
    (American Meteorological Society, 2023-10-16) Clive MAT; Doyle EEH; Potter SH; Noble C; Johnston DM
    Multiday severe weather outlooks can inform planning beyond the hour-to-day windows of warnings and watches. Outlooks can be complex to visualize, as they represent large-scale weather phenomena overlapping across several days at varying levels of uncertainty. Here, we present the results of a survey (n 5 417) that explores how visual varia-bles affect comprehension, inferences, and intended decision-making in a hypothetical scenario with the New Zealand MetService Severe Weather Outlook. We propose that visualization of the time window, forecast area, icons, and uncertainty can influence perceptions and decision-making based on four key findings. First, composite-style outlooks that depict multiple days of weather on one map can lead to biased perceptions of the forecast. When responding to questions about a day for which participants accurately reported there was no severe weather forecast, those who viewed a composite outlook reported higher likelihoods of severe weather occurring, higher levels of concern about travel, and higher likelihoods of changing plans compared to those who viewed outlooks that showed weather for each day on a separate map, suggesting that they perceived the forecast to underrepresent the likelihood of severe weather on that day. Second, presenting uncertainty in an extrinsic way (e.g., “low”) can lead to more accurate estimates of likelihood than intrinsic formats (e.g., hue variation). Third, shaded forecast areas may lead to higher levels of confidence in the forecast than outlined forecast areas. Fourth, inclusion of weather icons can improve comprehension in some conditions. The results demonstrate how visualization can affect decision-making about severe weather and support several evidence-based considerations for effective design of long-term forecasts.

    Mahi Tahi - Rū Whenua: Tangata Whenua & Kairangahau Pūtaiao. Reflective Learnings on Partnering With Indigenous Māori Communities in Field-Based Scientific Research
    (Wiley Periodicals LLC on behalf of American Geophysical Union, 2025-04-16) Mestel ERH; Smith B; Tapuke K; Illsley-Kemp F; Kaiser L; Connon I; Johnston D; Wilson CJN; Leonard G; Clive MAT; Savage MK
    Between 2018 and 2022, representatives of local Indigenous Māori communities and emergency management worked in partnership with physical and social scientists during the planning, deployment, and management of a temporary seismometer network around Taupō volcano. This deployment formed part of the Eruption or Catastrophe: Learning to Implement Preparedness for future Supervolcano Eruptions (ECLIPSE) project designed to increase understanding of the large caldera volcanoes in the central North Island of Aotearoa New Zealand. Here we critically reflect on this co-production approach to geophysical network deployment and associated volcano research. We identified a central theme of the creating and holding of space for researchers and communities to engage in the activities through adopting a co-production approach, that embeds representatives of local Iwi (tribal groups) Te Arawa and Ngāti Tūwharetoa as key researchers within a broad project team. We worked to ensure we were respecting communities' time, protocols, and decisions; and to exchange knowledge about the research and results with landowners, community leaders, schools, and young people. Time spent kanohi ki te kanohi (face-to-face) built relationships and trust within and outside the research team that have lasted beyond the scope of the ECLIPSE program. We detail our experiences in the hope of demonstrating that this approach to research is a possible and desirable path for future fieldwork-based research.
