Meteo: Unique timelapse video with the transport of African dust to our country

An impressive timelapse video was published by meteo.gr/National Observatory of Athens regarding the African dust that “suffocated” Athens during the two days of April 23-24.

As you will see in the footage recorded by the cameras of the Observatory in Penteli, the dust from the Sahara or “Minerva Red” within a few hours turned the landscape orange while making the atmosphere stifling.

“New episode maybe even more intense until mid-May”

The professor of Environmental Engineering at AUTH, Dimosthenis Sarigiannis, mentioned the phenomenon in a recent interview while sounding the alarm, considering that we will now encounter it more and more often.

“African dust is something we have encountered maybe 15 years ago”, he underlined and noted that now “we will have a greater frequency of phenomena and earlier in the summer season”.

“We expect to see at least one more new episode by mid-May”

According to the professor, the phenomenon “is characteristic of drought and the relative desertification of lands, resulting in the total volume of particles being much larger” and he noted that “wind flows change as the climate changes. This affects even more than the African dust.”

In fact, he estimated that an episode of African dust of similar and perhaps greater intensity is expected in May. “We expect to see at least one more episode of African dust by mid-May, which could be of the same intensity as the current one, maybe even more depending on the climatic conditions that will prevail,” he said.

However, he said “from May onwards things will be much better”, with a new episode expected in the autumn.

What causes concern

Mr. Sarigiannis emphasized the increased frequency of African dust as well as the duration of the episode and the volume of particles and stressed “this is a new element and it has to do with climate change”.

“The worrying thing” is, as he pointed out, “the fact that this burden with the interruption comes to be added to the particulate burden that we already have in the major urban centers of Greece, in Athens, in Thessaloniki, in Volos for example, in Ioannina, where the air quality, objectively speaking, is not very good in terms of particulates.”

“We should adapt to this, which means that the National Health System should also be ready to deal with acute cases of people who will have problems,” he added.

He concluded by saying that “we have to do both adaptation actions to be ready to deal with such acute episodes and on the other hand to do basic work really preventively, reducing the level of particle pollution in our cities, so that when it comes a few days that this wave coming from Africa does not come to settle on an already high background from atmospheric pollution”.
