Abstract
Between October 2023 and January 2024, a remarkably persistent cold air anomaly prevailed over Fennoscandia on an otherwise record‐warm planet. This article describes the temperature anomalies, atmospheric circulation and seasonal predictions associated with the cold blob. The 4‐month period from October to January was the third coldest in Fennoscandia during the ongoing century. The cold blob was associated with anomalous atmospheric circulation; for example, jet stream wind speeds were exceptionally high south of Fennoscandia. Furthermore, seasonal forecasts failed to capture the cold blob, which may be related to difficulties in simulating El Niño teleconnections by long‐range forecasting systems.
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.
