In fresh days Polish citizens have had the chance to experience an extraordinary atmospheric phenomenon. The usual sky gained a distinctive yellowish shade, which not only amazed but besides troubled many people. This phenomenon is the Saharic dust that invades Europe, all the way to our country, announcing not only changes in the landscape, but besides possible wellness effects.
Atmospheric anomaly: Sahara Dust
Nature sometimes surprises us with its whims, and 1 of them is the phenomenon of Sahara dust, which reached Poland at the turn of March and April. This is the effect of transporting dust from the Sahara Desert through advanced atmosphere layers over long distances. Thus, yellow clouds began to lag over many regions of Poland, drawing attention and raising interest.
Forecasts and Effects
According to synoptic forecasts, the main wave of Sahara dust is expected to hit Europe and Poland this weekend or early next week. The expected highest of dust occurrence over Poland is Sunday evening and night from Sunday to Monday. It is worth noting that the cloud of dust can lay over our country for a fewer more days, and the situation will only begin to normalize after about Wednesday 10 April.
Though the view of the yellow sky may seem impressive, it is worth remembering that the Saharan dust has consequences. Its presence contributes to increased concentrations of particulate substance suspended in the atmosphere, which can lead to increased symptoms in people with respiratory diseases or allergies. However, unless the phenomenon lasts besides long, it does not pose a serious wellness risk.
Trend Phenomenons: Saharian Dust in Europe
An interesting aspect of this phenomenon is the fact that Saharan dust over Europe, erstwhile observed sporadically, now appears much more often, even respective times a year. Scientists combine this frequency with the ongoing warming of the climate, which fosters violent erosion in the Sahara area and facilitates the long transport of sand particles through strong current air. Unfortunately, forecasts propose that this trend will increase and the Sahara dust over Europe will become even more common in the future.
Dust Transfer Mechanism
Sahary dust reaches Poland thanks to atmospheric complexities, which carry it for thousands of kilometres from the origin in the Sahara Desert, to various parts of Europe. It all starts with strong winds over the Sahara that lift dust and sand particles to the advanced layers of the atmosphere. Then, these molecules are transferred to long distances by high-level air currents, and the direction and velocity of their movement depend on many atmospheric factors.
Dust, crossing the Mediterranean Sea, will scope Europe, where it can be further carried by local air currents. This phenomenon is peculiarly visible in spring erstwhile the temperature contrasts between different regions are greater, which fosters the formation of strong winds. Reaching Poland, Saharic dust can origin different phenomena specified as yellow sky or surface cover with a thin layer of sand.
It is worth noting that while saharian dust may be a problem, it besides benefits. It contains minerals that can enrich the dirt on which it falls.
