Abstract

Tropical Storm Hermine hit the Canary Islands on 24–26 September 2022 as an extremely anomalous tropical cyclone. Hermine formed from an Easterly Wave that travelled from Sudan to the Atlantic. Hermine headed north and interacted with an extratropical trough over the Canary Islands, following the conceptual model of a Predecessor Rain Event, with precipitation characterised mostly by continuous accumulation rather than by convective intensity. In this article, modelled 24h precipitation is verified with spatial methods against satellite and station observations. The performance of the ECMWF high‐resolution model was similar or perhaps even better than a local, higher resolution model.

加那利群岛热带风暴 "赫敏 "降水量预报验证

2022 年 9 月 24 日至 26 日，热带风暴 "赫米娜 "作为一个极其反常的热带气旋袭击了加那利群岛。赫米娜 "由一个从苏丹吹向大西洋的东风浪潮形成。赫米娜 "向北移动，在加那利群岛上空与一个外热带低槽相互作用，遵循 "前雨事件 "的概念模式，降水主要以持续累积而非对流强度为特征。在本文中，利用空间方法对模拟的 24 小时降水量与卫星和站点观测结果进行了验证。ECMWF 高分辨率模式的性能与当地更高分辨率模式相似，甚至更好。

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.
