الآثار البيئية لرياح البوارح الهابة على المملكة العربية السعودية

Abstract EN

Bawareh is an old term given to the dry northern wind which is blown in the summer in the Arab peninsula.

The linguistic and geographical sources mentioned it in the old Arab tradition.

In the foreign studies, it is called Shamal.

This study was made to examine the environmental effects of this wind when it is blown on the kingdom of Saudi Arabia.

The study used the climatic data for 18 climatic stations distributed on all directions of the kingdom and follows the general authority for metrology and environment protection for the period 1985-2010.

The results showed that Bawareh wind has a great effect on the relative humidity in most of the studied stations where it brings drought for most of the stations, especially the coastal stations, but the rates of the relative humidity is greatly decreased during the blown wind.

As to the effect of Bawareh on the temperature it is limited.

The study discovered that the two phenomena: the sand driftage and the dust are the most dangerous natural environmental effects resulting from the blown wind of Bawareh on the studies region.

The eastern and northern areas are the most affected areas of Bawareh wind in the kingdom due to the increased repetitions, the quickness of the northern and the western northern winds and for the geographical nature of their lands.

These natural effects resulted in a number of negative human effects including its effect on the health of the man, the population assembly, and different means of transport and on tourism and agricultural sectors.
