Abstract

Anthropogenic (industrial) snowfalls in the UK have hitherto been regarded as rare and extremely localised. This article analyses the distribution and possible causes of three ‘stripes’ of anthropogenic snow extending up to 10 km from the vicinity of London’s Heathrow airport on 23 January 2023. The early morning had been exceptionally cold at the airport, partly due to the relatively late arrival of freezing fog compared to other parts of the lower Thames valley. This is likely to have facilitated the formation of the snowfall by means of ice nuclei.

2023 年 1 月 23 日英格兰东南部雾凇期间的线性降雪轨迹：人为降雪的证据

迄今为止，英国的人为（工业）降雪一直被认为是罕见和极其局部的。本文分析了 2023 年 1 月 23 日在伦敦希思罗机场附近出现的三 "条 "状人为降雪的分布情况和可能原因。当天清晨，机场异常寒冷，部分原因是与泰晤士河下游其他地区相比，雾凇来得相对较晚。这很可能有助于冰核形成降雪。

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.
