Many people did not keep the experience of looking at pink to blood-colored redheads to themselves, they shared them on social networks.
The image of photographer Lukáš Gall, who captured Malý and Velký Roklan in Šumava under the redheads, caused astonishment. “It took about eight minutes for the sun to peek into the gap between the clouds and the horizon and the sky turned red,” he said. It was five degrees below zero at the time. “When it freezes, the conditions are ideal for taking photos, and in this case, the landscape under the red sky turned beautiful purple,” the photographer added.
Dust and vapors
The formation of reds is associated with dust particles in the air and a high content of water vapor, which condenses on their surface due to the low air temperature. It refracts the sun’s rays and scatters the red part of the spectrum so that we can see the red sky.
Červánky reports a change
Evening blushes often signal to us that the next day will be dry and sunny weather. “On the contrary, the occurrence of morning blushes due to the large amount of water vapor in the atmosphere usually indicates a worsening of the weather,” said Metricologist Dagmar Honsová, adding that if they are colored deep red at the bottom, it will most likely be a cold front.
The sky was colored by the eruption of a volcano
“In Central Europe, the highest incidence of redheads was in 1883 and 1884 after the eruption of Krakatoa volcano. Thanks to the large number of dust and other parts, they were observed 1.5 hours after sunset, “reminded meteorologist Dagmar Honsová.
The day before the red sunset, people in some parts of the Czech Republic caught another amazing meteorological phenomenon. A halo effect has been created in the sky, which appears around the Sun and the Moon in the form of wheels and arcs. And while redness is caused by steam refracting light on dust particles, this phenomenon is caused by the reflection and refraction of rays on tiny ice crystals. The presence of crystals scattered from snow often contributes to its formation.
