The Khamsin weather depressions have not yet begun, despite the recent heavy dust.

Arab Weather - Weather analyses at Arab Weather indicate that the dust waves that affected the region recently were caused by the rush of cold air masses towards the central Mediterranean Sea, which contributed to the formation of deep atmospheric depressions in those areas.

These low-pressure systems led to significant atmospheric pressure differences, which in turn caused brisk to strong winds, particularly over the desert regions of Libya and Algeria. These winds stirred up large quantities of dust and sand, which subsequently moved towards the eastern Mediterranean basin.

As it moved, these dust waves first affected Libya and Egypt, before later extending towards the Levant, causing the dusty conditions that were observed during the past few days.

Why are these cases not considered to be of a fifty-day nature?

The Khamsin depressions are mainly associated with high temperatures on land, especially in the north of the African continent, and are accompanied by warm air masses. However, the recent cases were associated with cold surges, and the necessary thermal dynamic conditions for classifying them as Khamsin depressions were not available, despite their similarity in terms of dust effects.

When do the fifty-day lows actually begin?

It is expected, God willing, during the coming period, specifically with the progress of the second half of April and during the month of May, that the actual activity of the Khamsin weather depressions will begin in the region, and this will coincide with a clear and increasing rise in land temperatures, especially in the regions of North Africa.

Characteristics and effects of the Khamsin depressions

Khmelnyt depressions are characterized by their dynamic nature and sharp weather fluctuations, where:

It usually begins with a noticeable rise in temperatures at the front of the low-pressure system, as a result of the influx of warm, dry air masses.

This is accompanied by a noticeable increase in dust-raising winds, leading to dusty conditions and possibly dust storms in some areas.

This is followed by a noticeable drop in temperatures after the cold front passes through.

It may sometimes cause atmospheric instability, accompanied by thunderstorms and rain in some areas.

And God knows best.
