| Abstract: | Examines effect of meteorological and regional climate changes on winter road between Tulita and Norman Wells, NWT, which has been open since 1982. Statistical analysis of opening dates for winter road showed five seasons with extremely early dates and five with extremely late dates. Extremely early-opening seasons are distinguished by anomalously high sea-level pressures, anomalously cold tropospheric air, and north-westerly surface winds during November prior to road opening. Extremely late-opening seasons are characterised by anomalously strong Aleutian low in preceding November. |
