The city of Al Zulfi is located in the middle of the Arabian Peninsula, surrounded by sand on all sides, its climate is dry throughout most of the year, its rains are few and irregular, it falls in the winter, the average rainfall does not exceed 100 mm annually, and storms begin in March and increase its concentration in April and May.
Dust storm occurs when there are several conditions: soft soil, lack of vegetation, and reaching a horizontal wind speed of 20 km / h or more.
The research aims to show the relationship between negative human activity in the desert environment, the number of occurrences of dust storms, and the high level of dust in the air of Al-Zulfi city.
The study found results, that the destruction of the soil due to human activity such as overgrazing and logging contributed greatly to the increase in the number of dust storms 185 even if there was a rise in the rate of rainfall 128 mm as happened in 2018.
