Arab Weather - In the period between May and July, mainly dry, hot and dusty northwest winds blow over many countries of the Arabian Gulf and are known locally as " Al-Bawareh Winds ". The intensity of the Al-Bawareh winds varies from year to year, and it may be severe at times. Significant changes in the weather, up to the disruption of some aspects of life in different regions.
Al- Bawareh winds arise as a result of a difference in atmospheric pressure values between different countries and regions in the Arab world, as a result of the difference in specific heat between land and water, and because the land gains heat faster than water, the air expands on the surface of the land and the atmospheric pressure decreases, and then the atmospheric pressure becomes above sea water. With a high percentage of water, areas with high atmospheric pressure values are generated over the waters of the Mediterranean.
This coincides with a deepening of the seasonal depression called the India seasonal depression, affecting 3 continents, including most of the countries of the Arabian Peninsula. The India seasonal depression has several centers in the Arabian Peninsula, especially over Kuwait and southern Iraq, characterized by its depth and the decline in atmospheric pressure values.
As a result of the distribution of such air systems in the Arab world, and as a result of the different values of atmospheric pressure (the force of atmospheric pressure gradient), the wind moves from the values of atmospheric pressure towards the values of low atmospheric pressure, so that it blows in a northwesterly direction, which is known as the Al-Baarih winds as mentioned above, and the intensity of the winds varies according to Exacerbation of the impact of India's seasonal depression on the Arab Gulf states.
Al- Bawareh winds affect many Arab Gulf countries, some of them mainly and some secondarily, and the countries affected mainly in the Bawareh winds are Iraq, Kuwait, and eastern Saudi Arabia, extending to wider areas sometimes, including the capital, Riyadh.
The influence of the Al-Bawareh wind sometimes affects other countries such as Bahrain and Qatar to the UAE and later the Sultanate of Oman, and the influence of the dust-laden Al-Bawareh winds extends through Saudi Arabia to the State of Yemen.
The influence of the Al-Bawareh winds results in many damages and has negative effects that are not limited to humans, and among the damages that may result from the Al-Bawareh winds are that they lead to the formation of dust waves and strong sandstorms and cause sand encroachment in strong cases, which leads to some countries having to stop vital activities In the country, such as the disruption of air traffic and marine navigation due to high sea waves and the lack of horizontal visibility, which has a negative impact on the economy of countries. Respiratory and eye patients are greatly affected during the gusty winds, and diseases such as allergies and asthma spread.
The influence of the Al-Bawareh wind is not limited to that only. Animals, trees and plants are negatively and directly affected during the Al-Bawareh winds, causing the death of some animals and the breaking of trees.
Certainly, the damage caused by the blowing of the Al-Bawareh winds can be avoided by many methods, the most important of which is planting trees to reduce the intensity of the winds (making windbreaks), which will positively affect the wind speed and soil cohesion and thus reduce dust resulting from wind activity, for more on that .
