Starting from the vernal equinox, the daylight hours are gradually increasing in the northern hemisphere, as a result of the sun's gradual movement towards the north, which leads to an increase in the amount of solar radiation that reaches our region and thus temperatures tend to gradually rise.
It begins with the vernal equinox, usually called the five -year period, during which depressions are generated in the south of the Atlas Mountains in the Maghreb, and they move towards the east and travel near the coasts of North Africa until they reach the eastern Mediterranean region.
These pentagonal depressions are usually preceded by hot, dry south winds laden with dust and dust called the pentathlon, which often leads to infections in the throat, eyes and respiratory system due to suspended materials carried by the pentathlon.
Dust also causes a decrease in horizontal visibility, which leads to the disruption of vehicle movement and the closure of some airports, ports and public facilities in many countries of the region.
Dry winds will be followed by moist westerly or northwesterly winds, which may be accompanied by rain with thunder showers, which are described as "mud rain" because of the dust attached to them during their rains.
