Abstract

fetched live from OpenAlex

Extreme wind and snow loads can be critical structural design parameters for Alaska. Understanding these extreme climate conditions under climate change conditions is valuable for adaptation and community resilience. Wind or snow loads can be the principal climatic loads, and the other can be the companion load. The effect of climate change on these two extreme climatic variables deserves investigation. Moreover, how climate change impacts both extreme climatic variables is still being determined; it is also worth understanding the spatial effect of climate change over Alaska for each hazard. For this purpose, this study investigated a large ensemble of simulations under a high-emissions climate change scenario to analyze the uncertainties of the future extreme wind climate and snow loads for Alaska. The impact of climate change on the design level of extreme events was investigated. The nonstationarity of the extreme wind speeds and ground snow loads under climate change scenarios were examined. The effects of the nonstationarity on determining the design wind speeds and ground snow loads are discussed. The correlation between the extreme wind speeds and ground snow loads is explored to understand how to consider the companion climatic loads in climate change scenarios. Uncertainties associated with future projections are explored. Structural design for climate change adaptation and community resilience in extreme wind and snow hazards is discussed.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
