| Abstract | In this study, we test the significance of identified meteorological forcing variables against a long-term dataset of icing dynamics and distribution developed for the Yellowknife region, Northwest
Territories. Overall, 28% of icing density interannual variation is explained by winter warming periods (>5°C) and autumn rainfall. Interannual icing density variation and significant meteorological forcing variables differ among ecoregions where
varied geological permafrost conditions influence the hydrological regime. |
| Summary | (Plain Language Summary, not published)
In this study, we test the significance of identified meteorological forcing variables against a long-term dataset of icing dynamics and distribution
developed for the Yellowknife region, Northwest Territories. Overall, 28% of icing density interannual variation is explained by winter warm waves (>=5°C) and autumn rainfall. Interannual icing density variation and significant meteorological forcing
variables differ among ecoregions where varied geological permafrost conditions influence the hydrological regime. |
