Abstract The paper presents climatology of the poorly known, particularly at high latitudes, short-period (8- and 6-h) tides observed by meteor radars at high latitudinal stations Tromso (70°N, 19°E) and Svalbard (78°N, 16°E) based on 16 years (2003–2018) and 18 years (2001–2018) of measurements, respectively. The main focus of this study is to clarify the seasonal variability and vertical structure of the two tides observed at both sites. It is found that at the two not very distant high-latitude stations Tromso and Svalbard both tides have not only different seasonal variability but also some distinction in the altitude structure as well. In general the short-period tides at both sites are vertically upward propagating waves but with seasonally depending vertical wavelength. The two tides at Tromso and the 8-h one at Svalbard reveal some inter-annual variability with a period of quasi-2 years. An assessment of the solar heating as the main mechanism for the generation of the 8- and 6-h tides simulated by the model WACCM6 is presented as well. The results could be used as benchmarks for model simulations and for understanding better the forcing mechanisms of these short-period tides at high latitudes.

特罗姆瑟和斯瓦尔巴群岛的流星雷达观测到的短周期（8 小时和 6 小时）潮汐的气候学

摘要 本文介绍了在高纬度站特罗姆瑟（北纬 70 度，东经 19 度）和斯瓦尔巴特群岛（东经 78 度）的流星雷达观测到的鲜为人知的气候学，特别是在高纬度、短周期（8 小时和 6 小时）潮汐。 N, 16°E) 分别基于 16 年 (2003–2018) 和 18 年 (2001–2018) 的测量结果。本研究的主要重点是阐明在两个地点观测到的两个潮汐的季节性变化和垂直结构。发现在两个不是很远的高纬度站特罗姆瑟和斯瓦尔巴两个潮汐不仅有不同的季节变化，而且在海拔结构上也有一些区别。一般来说，两个站点的短周期潮汐都是垂直向上传播的波浪，但具有季节性的垂直波长。特罗姆瑟的两次潮汐和斯瓦尔巴群岛的 8 小时潮汐揭示了一些年际变化，周期为准 2 年。还介绍了对太阳能加热作为 WACCM6 模型模拟的 8 小时和 6 小时潮汐产生的主要机制的评估。结果可用作模型模拟的基准，并可用于更好地了解这些高纬度短周期潮汐的强迫机制。
