The apocalypse images that we all saw yesterday Tuesday (23/4/2024) referred to a scene from the Sahara desert. However, at noon on Wednesday (24/4/2024) the orange cloud leaves and in most areas of the country the sun shines again. But apnea combined with high temperatures make a dangerous “cocktail” for our health.
This event mobilized the medical associations and the Ministry of Health, who recommend to vulnerable groups not to be exposed for long hours outside and to wear masks.
The Hellenic Geological and Mining Research Authority prepared a particularly interesting study on the composition of African dust. Collecting and analyzing, using the new state-of-the-art JSM-IT500L scanning electron microscope, which has the ability to magnify up to 300,000 times, a sample of the African dust that has blanketed Attica confirmed what pulmonologists had been ringing the bell about all along space. In other words, in addition to the African dust, dangerous elements (suspended particles) that are transported due to it pass through our respiratory system.
Weather: The components of dust
In particular, while optically the dust does not exceed 10μm in size, its chemical composition includes the elements aluminum (Al), silicon (Si) and calcium (Ca) with a minimum percentage of iron (Fe) and titanium (Ti). And as pointed out in the EAGME announcement, the African dust is in essence a plaything that floats and moves due to the wind and its small size.
It is gradually moving away from the west of the country
The African dust that carries particles in a wide range of sizes, such as PM10, PM2.5 or even much smaller, while it can also carry pollutants from the atmosphere according to ERT meteorologist Panagiotis Yiannopoulos, is gradually moving away from the west of the country. In particular, this afternoon the phenomenon will have been limited to the eastern Aegean and by evening the atmosphere will have cleared.
The Ministry of Health, following the regularly scheduled briefing by the Ministry of Environment and Energy (last briefing today at 8:00) and within the framework of its responsibilities for the protection of public health, recommends the following instructions for informing the public with precautionary measures as following:
A. Recommendations for people at increased risk
People with respiratory problems, heart patients, children, as well as people over 65 years of age:
They should avoid any physical exercise-activity outdoors.
It is also recommended to avoid staying outdoors, especially in areas with increased traffic.
People with asthma may need more frequent inhalations of reliever medicine. If symptoms persist, it is recommended to contact the attending physician.
B. Recommendations to the general population
Every person is advised to avoid any physical exercise outdoors and to limit the time spent outdoors especially in areas with increased traffic. During his stay indoors, keep doors, balcony doors and windows closed.
Weather: The African dust is leaving, the rains are coming
According to Sakis Arnautoglou, the weather is expected to be generally good on Friday and the weekend with weakened winds on the seas and good temperatures for the season.
At the same time, as he adds, according to today’s data, from next Sunday and most of the days of Holy Week, the weather conditions will be good “in most areas of the country with a few local showers in the mountains of central and northern Greece during the warm hours of day”.
See on the maps where it will rain on Thursday:
Weather: Sakis Arnautoglou’s post
“Thursday’s rains every six hours at a glance! The dust gradually recedes from the west to the east until late tonight.
Winds on Thursday will blow from west directions 3 to 5 in the northern Ionian and northern Aegean, and at 5-7 Beaufort in their southernmost parts. The temperature at noon at 20-24 degrees in the north, 20-21 degrees in the west, 25-27 in the eastern mainland and 22 to 24 degrees in the Aegean islands.
In general, the weather will be good next Friday and Saturday with weakened winds on the seas and good temperatures for the season.
According to today’s data, from next Sunday and most days of the Holy Week, the weather will remain good in most areas of the country with a few local storms in the mountains of central and northern Greece during the warm hours of the day. Midday temperatures will remain at fairly normal levels for the season, along with relative coolness at night and in the morning hours.
As for the winds during the Holy Week, northerly winds should prevail, which only in the Aegean will reach 5-7 and possibly in the Cyclades locally 8 Beaufort).
Although relatively far away, with today’s forecast data, the weather for Easter Sunday remains puzzling in terms of the possibility of occurrence of phenomena and in which regions of the country because in terms of temperature it should still be looking towards spring”.
African dust: When will Athens clean up?
THE African dust begins to move towards the east, “relieving” the Greek atmosphere from the large amounts.
According to the prognostic data of the DUST/METEO system of the National Observatory of Athens, the strong episode of transport of Saharan dust called “Minerva Red” occurring in our country is expected to subside during today’s day.
The prevalence of west-northwest winds will result in the progressive transfer of high concentrations of dust to the Aegean, while tomorrow high concentrations of dust will be located in the Dodecanese.
