Saudi Arabia | Indications of the possibility of dust waves rushing from Sudan to the southwest of the Kingdom next week

Weather of Arabia - Sinan Khalaf - It seems that the southwestern sector of the Kingdom is on a date with the possibility of renewed activity of what is known locally as the "dust season", as maps of wind movement indicate that the region is exposed to northwesterly winds, coming from Sudan and is expected to carry with them varying amounts of Dust and dust, accompanied by a significant decrease in the horizontal visibility.

What is the dust season?

Al-Ghubra season. This name is given by the local population in the southwestern coasts of the Kingdom to the active monsoon winds, which raise dust waves on the southwestern coasts of Saudi Arabia, including the governorates of Al-Laith and Al-Qunfudhah and extending to the coasts of Jazan.

What are the scientific reasons for the dust season?

Al-Ghubra season is due to the deepening of the Sudan depression, as it pushes moderate to brisk southwesterly winds, raises dust in Sudan and rushes part of it, especially to the heights of Jazan and Asir and sometimes Al-Baha and Taif, coinciding with the activity of wind movement on the coasts of the Red Sea, which raises dust locally on coastal roads .

When does the dust season end?

Climatically, the seasonal dust season usually begins with late June and continues until mid-August, and waves on dust reduce horizontal visibility, which negatively affects respiratory patients.
