Accurate assessment of extreme wind gusts is important for many infrastructure requirements, particularly in building design standards and for insurance purposes. In a previous paper (Aylott et al., 2020), Northern Ireland's record wind gust – 108kn (56ms−1) recorded at Kilkeel on 12 January 1974 – was critically re‐examined, and found to be almost certainly incorrect due to instrumental error or a power surge. A recommendation was made that other longstanding United Kingdom record wind gusts should also be independently re‐examined to assess their veracity. In this paper the arguments for and against the authenticity of the current record low‐level wind gust for Scotland, and the UK national record, namely 123kn (63ms−1) recorded at the Kinnaird Head Lighthouse at Fraserburgh on 13 February 1989, are reviewed. Two ‘gusts’ >100kn were probably record artefacts owing to brief power supply interruptions to the recording anemograph, and accordingly neither should remain included in the list of national wind speed records.

重新审查了英国最高的低层风速:1989年2月13日的弗雷泽堡阵风

准确评估极端阵风对于许多基础设施要求非常重要,特别是在建筑设计标准和保险目的中。在上一篇论文(Aylott等人,  2020年)中,对北爱尔兰的创纪录阵风– 1974年1月12日在基尔基尔记录的108kn(56ms -1)进行了严格的重新检查,并且由于仪器误差几乎可以肯定是不正确的。或电涌。有人建议,也应重新检查其他长期存在的联合王国记录的阵风,以评估其准确性。在本文中,论证了苏格兰目前创纪录的低空阵风和英国国家创纪录的123kn(63ms -1)于1989年2月13日在弗雷泽堡的Kinnaird Head灯塔录制。由于记录风速仪短暂的电源中断,两次超过100kn的“阵风”可能是记录伪影,因此都不应该保留在国家风速记录列表中。
