摘要

2023 年 11 月 1-2 日午夜前，海峡群岛的泽西岛遭受了一场大型龙卷风和严重冰雹袭击。通过分析雷达数据，探索了母体超大型雷暴的形态。在偏振场中，龙卷风碎片云非常明显，与反射率 "碎片球 "同处一地。碎片云包括一小块相关系数极低（0.8）的区域，其反射率差值≤0dB。在垂直剖面上，碎片特征包括一个低相关系数和高反射率的柱体，随着高度的增加向北-东北倾斜，并延伸到离地面至少 2 千米的地方。

Polarimetric radar observations of the Jersey tornadic supercell on 1–2 November 2023

A large tornado and severe hailstorm struck Jersey, Channel Islands, just before midnight on 1–2 November 2023. Radar data are analysed to explore the morphology of the parent supercell thunderstorm. A tornado debris cloud was evident in polarimetric fields, collocated with a reflectivity ‘debris ball’. The debris cloud comprised a small region of exceptionally low correlation coefficient (<0.8) collocated with differential reflectivity ≤0dB. In vertical section, the debris signature comprised a column of low correlation coefficient and high reflectivity that tilted north‐northeast with height and extended to at least 2km above ground level.

期刊介绍： The aim of Weather is to act as a bridge between the interests of those having a professional and a general interest in the weather, as well as between meteorologists and others working in related sciences such as climatology, hydrology and geography. Articles and regular features are written for a wide range of readers, from professional meteorologists to amateur weather observers. While technical language and mathematical content are kept to a minimum, Weather also seeks to inform and to give readers an opportunity to update their subject knowledge. Weather is also the ''house journal'' of the Society and seeks to keep the reader up-to-date with Society news and includes meeting and conference reports, a Readers'' Forum series and occasional Viewpoint articles. Photographs of weather events are an important feature of the journal and the Weather Image feature provides an opportunity to analyse a satellite image or photograph. Weather Log is a summary of the weather of each month by means of meteorological data and weather maps.
