Burgundy Swathed in Fog: Dijon Faces Prolonged Period of Dim Days
Table of Contents
Teh city of Dijon has been largely obscured by fog as December 16th, a meteorological reality residents of the Burgundy region have become accustomed to, with an average of 70 foggy days each year. While Dijon experiences frequent fog, it isn’t alone – and isn’t even the most affected city in France.
A Persistent Phenomenon in Burgundy
For weeks, residents of the Côte-d’Or department have woken to a landscape veiled in thick fog.This phenomenon is notably common in the region, frequently enough referred to as the “Burgundy fog,” but its prevalence doesn’t necessarily indicate a recent change. According to one official from Météo France Nord-Est, data indicates a consistent pattern. “Between 1961 and 1990, the results were roughly the same, so there is no marked trend in Burgundy,” they stated.
However, the fog’s impact isn’t uniform across the region. Certain areas experience even more prolonged periods of reduced visibility. “in the Hautes-Côtes, Langres plateau, Sombernon and Morvan sectors, we have an average of 80 to 100 days per year,” explained thibault Mascia, administrator of Météo Côte-d’Or.
Dijon’s Foggy Ranking & National Comparisons
While Dijon is considerably impacted,it doesn’t rank among the top cities in France for fog. The city surpasses Langres (77 days of fog annually), Mont-de-Marsan (78 days), and limoges (82 days) in terms of foggy days. Initial reports suggested Limoges might be the “capital of fog,” but Mascia clarifies that Charlevilles-Mézières actually holds that distinction, with a striking 108 days of fog per year.
The contrast is stark when compared to regions with more temperate climates. Cities along the Mediterranean coast experience significantly less fog. Toulouse averages just 30 foggy days per year, while Montpellier sees only 19. nice, remarkably, experiences an average of just one short day of fog annually.
The Science Behind the Mist
The fog that blankets Dijon is primarily “radiation fog,” a common type formed under specific atmospheric conditions. As one meteorologist explained,this type of fog occurs in anticyclonic conditions when the ground cools overnight,lowering the temperature of the air above. “As this air mass cools, it condenses. The water which was in the form of water vapor therefore transforms into droplets: it is fog,” they said.
This process is most prevalent in low-lying geographical areas – plains, valleys, and wetlands – typically ranging from 0 to 5
Why is Dijon experiencing prolonged fog? Dijon is experiencing prolonged fog due to a consistent meteorological pattern of radiation fog formation, particularly during anticyclonic conditions where the ground cools overnight, causing water vapor to condense into droplets. This is a typical occurrence in the Burgundy region.
Who is affected? Residents of the Côte-d’Or department, and specifically the city of Dijon, are most affected by the fog. Though, other areas within Burgundy, such as the Hautes-Côtes, Langres plateau, Sombernon, and Morvan sectors, experience even more frequent and prolonged fog.
What is the impact of the fog? The fog causes reduced visibility,impacting daily life for residents and potentially affecting transportation. While Dijon isn’t the foggiest city in France, it experiences an average of 70 foggy days per year, with some areas seeing up to 100.
How did it end? The article does not state that the fog has ended. It describes a current, ongoing situation that began on December
