In addition, these atmospheres are accompanied by strong, active winds with strong gusts of speed, which cause waves of dust, dust and possibly sandstorms in large areas of Saudi Arabia, thus reducing the horizontal visibility significantly in some areas ... more details in future reports.
The Arab Weather forecast staff attributed these possible weather fluctuations to the control of a high-pressure air system over the western and central Mediterranean and southern Europe, which will push the defense of cold basins and upper air depressions towards the eastern Mediterranean and the northern Red Sea.
The forecast staff indicated that these depressions may be associated with the crossing of cold air fronts over northern Saudi Arabia, thus forming thunderstorms.
The staff also expected a decrease in the strength of the air height that dominated Saudi Arabia during the past days, and thus improved chances of moisture penetration into the layers of the atmosphere over Saudi Arabia.
