In Aveyron, the phenomenon of the “sky of fire” was seen at daybreak, this Thursday, November 14, 2024. What does it consist of and how can we explain it?
A superb show was seen in Aveyronthis Thursday, November 14, 2024, at daybreak: a “sky of fire” was formed above heads, notably in Millau. How to explain it?
It can happen anywhere, but…
According to the Futura Sciences website, this phenomenon, described as natural, can occur anywhere in the world, although areas of the globe are advantaged compared to others. This famous conflagration of the sky actually depends on several factors: the weather situation and the composition of the atmosphere at time T, in particular.
The issue of light and clouds
The Weather Channel then explains that at sunrise and sunset, sunlight plays a major role in the formation of this “sky of fire”. Indeed, this light travels a long way in the atmosphere. A piece of data then comes into play: more it meets moleculeswhether it is humidity or pollution to name a few, the better it spreads. And above all: its colors at low wavelengths disappear. As a result, the color of the sky and the sun changed pink, orange or red.
Futura Sciences adds by explaining that the best time to see this phenomenon is located 10 to 15 minutes after the start of sunset. On this occasion, the role of clouds is also preponderant. The Weather Channel reports that the presence of high clouds favors this spectacle, the reddest rays can still be reflected there even after going to bed. But it can also be seen in the morning so, as this was the case in Millau.
An ally of storms?
In relation to these same clouds, Futura Sciences finally concedes that shower or storm clouds are the most conducive to these “fiery skies” since it is, as a reminder, important that the light of clouds crosses paths with a large quantity of molecules. Note that among the components favorable to the arrival of this phenomenon is also sand.
