Some reports of snowfall from fog during the UK winter of 2008/09

TL;DR

This paper reports observations of snowfall occurring during foggy, anticyclonic conditions in the UK winter of 2008/09, highlighting its unexpected nature and potential impacts on transport and surface albedo.

Contribution

It provides rare observational data on snowfall during foggy conditions, a phenomenon often not forecasted and poorly understood.

Findings

Snowfall occurred during freezing fog in the UK winter of 2008/09

Such snowfall can impact transportation and surface properties

It challenges typical weather forecasting assumptions

Abstract

Snowfall during anticyclonic, non-frontal, and foggy conditions is surprising. Because it is often not forecast, it can present a hazard to transport and modify the surface albedo. In this report, we present some observations of snowfall during conditions of freezing fog in the UK during the winter of 2008/09. [v2 includes typographical corrections]
