An atmospheric river and a quasi‐stationary front lead to heavy rainfall and flooding over Scotland, 6–8 October 2023.

In October 2023, Scotland experienced heavy rainfall and flooding due to an atmospheric river and a quasi-stationary front. This event was unusual and different from previous flood events in Scotland. The flooding caused widespread damage, including landslides, road closures, and loss of crops. The synoptic meteorological situation involved a continuous advection of a humid air mass and a temperature and humidity contrast across the front. It is important to note that extreme precipitation events like this may become more severe in a warmer climate. [Extracted from the article]
