Abstract
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.
