Wind speed analysis is important for informing airport operation and safety. Many communities in the Hudson Bay and Labrador regions (Canada) are remote communities that rely heavily on aircraft for passenger and freight movement. Historical trends in average daily wind speed and maximum daily wind speed from 1971 to 2010 were examined to identify patterns of change and determine how these changes may influence aviation in six northern communities across Hudson Bay and Labrador in Canada. Significant increases in average wind speed and maximum wind speed were found for some of the months and seasons of the year for the Hudson Bay region, along with a significant decrease in those variables for the Labrador communities. Average wind speeds at multiple locations are approaching the threshold (18.5 km/h or 10 knots) when take-off and landing would be restricted to one direction. The results of this study agree with previous research that examined historical patterns for wind speed in these regions but calls into question climate change impact assessments that suggest wind speeds will continue to increase under future climatic conditions for this study area. Future research is needed to further analyse shifts in prevailing wind directions and changes in the frequency of extreme wind conditions, to better understand the potential impacts of projected climate change on this climatic variable and the implications these changes may have on applied sectors, such as aviation.

从航空角度表征加拿大哈德逊湾和拉布拉多地区观测到的地面风速

风速分析对于告知机场运营和安全非常重要。哈德逊湾和拉布拉多地区(加拿大)的许多社区都是偏远社区,严重依赖飞机进行客运和货运。研究了 1971 年至 2010 年平均每日风速和每日最大风速的历史趋势,以确定变化模式并确定这些变化如何影响加拿大哈德逊湾和拉布拉多的六个北部社区的航空业。哈德逊湾地区在一年中的某些月份和季节发现平均风速和最大风速显着增加,而拉布拉多社区的这些变量则显着减少。多个地点的平均风速正在接近阈值 (18. 5 公里/小时或 10 节)当起飞和着陆将被限制在一个方向。这项研究的结果与先前研究这些地区风速的历史模式的研究一致,但对气候变化影响评估提出了质疑,该评估表明,在该研究区域的未来气候条件下,风速将继续增加。未来的研究需要进一步分析盛行风向的变化和极端风条件频率的变化,以更好地了解预计的气候变化对这一气候变量的潜在影响以及这些变化可能对航空等应用部门产生的影响. 这项研究的结果与先前研究这些地区风速的历史模式的研究一致,但对气候变化影响评估提出了质疑,该评估表明,在该研究区域的未来气候条件下,风速将继续增加。未来的研究需要进一步分析盛行风向的变化和极端风条件频率的变化,以更好地了解预计的气候变化对这一气候变量的潜在影响以及这些变化可能对航空等应用部门产生的影响. 这项研究的结果与先前研究这些地区风速的历史模式的研究一致,但对气候变化影响评估提出了质疑,该评估表明,在该研究区域的未来气候条件下,风速将继续增加。未来的研究需要进一步分析盛行风向的变化和极端风条件频率的变化,以更好地了解预计的气候变化对这一气候变量的潜在影响以及这些变化可能对航空等应用部门产生的影响.
