Arabian Gulf | A significant weather phenomenon disappears from Saudi Arabia and the Gulf during the fall.

Arab Weather App - Sandstorms and dust storms are hitting large parts of the Arabian Peninsula, particularly Iraq and the Gulf states, including Saudi Arabia. These storms often negatively impact transportation and navigation in various forms, whether by land, sea, or air. They also pose a direct threat to the health of citizens and residents, leaving a clear impact on the environment and the agricultural sector.

As autumn approaches, the intensity of sandstorms and dust storms gradually begins to decline. Statistical studies show that autumn is the season least affected by sandstorms compared to other seasons, for several reasons, the most important of which are:

Decrease in thermal differences:

With the onset of autumn, the large temperature differences between the north and south of the Arabian Peninsula decrease, limiting the strength of air currents that cause dust and sand storms. This results in a more stable climate compared to the hot and dry seasons.

High humidity:

In autumn, atmospheric humidity increases as sea winds penetrate deeper into the interior atmosphere, causing dust and sand to settle on the Earth's surface. This reduces sand movement and reduces the chances of dust storms.

Low wind speed:

Northwesterly winds, which are a major cause of sandstorms in spring and summer, subside in autumn, significantly reducing the intensity of the phenomenon.

Effect of vegetation:

During the fall, some areas experience limited seasonal vegetation growth due to improved climatic conditions. Even if this growth is modest, it plays an important role in stabilizing the soil and reducing sand and dust blown by the wind.
