Weather of Arabia - The first half of the year 2021 has passed and the weather systems have begun to take the summer form and gradually acquire its characteristics, as on Tuesday the first of June coincides with the beginning of the summer season in the northern part of the globe according to meteorology, and colleague Muhammad Al Shaker reviews you in a video Its duration is one minute, the most prominent changes to the weather regulations and the prevailing weather phenomena in the Kingdom of Saudi Arabia during the summer.
As, coinciding with the beginning of the summer season, the region is affected by several changes in the weather systems, and perhaps the most important of them lies in the decline of rainfalls in most parts of the Kingdom of Saudi Arabia, with the exception of parts of the south and southwest of the Kingdom of Saudi Arabia, where these areas are affected by so-called monsoon rains as a result of the continuous rush of humid winds from African regions. And the Arabian Sea due to a surface extension of the Red Sea Depression on more than one occasion during the summer, and here are these points that summarize the most prominent weather factors prevailing in the summer of the Arabian Peninsula.
The upper air height dominates the Arabian Peninsula as a result of the increasing influence of solar radiation during the summer season, accompanied by extremely hot air masses that deepen surface thermal depressions with very low values on most of the eastern Arabian Peninsula and deepen whenever we head to the southern part of the Arabian Peninsula due to the nature of the terrain Located in the eastern and southern parts of the Arabian Peninsula, especially the Empty Quarter, this air system, God willing, works to raise temperatures in addition to heat waves, causing temperatures to rise to about fifty degrees Celsius in some areas.
During the first half of the summer season, and as a result of the distribution of air systems represented by a rise in surface air pressure in the regions of the Levant, while it is offset by a decrease in the values of atmospheric pressure in the east and south of the Arabian Peninsula as a result of the formation of thermal depressions, where the large difference in the air pressure between the two air systems leads to the emergence North to northwest winds, or the so-called Al-Bawareh winds, these winds are active and are characterized by their severe dryness and constant excitation of dust and dust, leading to the formation of sandstorms at times on parts of eastern and central Saudi Arabia.
What is known as the ITCZ orbital separator affects the central African continent in these months, specifically from May to October, while the orbital separation gradually rises towards parts of the Arabian Peninsula during July and August as a result of the trade winds from the northern and southern hemispheres.
On the other hand, starting from the beginning of June, southwesterly winds, or what is known as monsoons, rush in the regions of the Indian subcontinent, where they carry with them very large quantities of relative humidity in the various layers of the atmosphere to increase the density of thunderstorms and increase the rain in them, where and with the presence of India's seasonal depression a convergence occurs These winds lead to the formation of torrents and floods in these areas, especially during the months of June and July.
The impact of these weather systems on the Arabian Peninsula and the Arab world in general differs from one season to another, and parts of Somalia and Sudan down to parts of southern and southwestern Saudi Arabia, Yemen and the Sultanate of Oman are usually affected by the activity of cumulonimbus rain clouds, bringing with it monsoon rains, especially during the months of July and August with peak fluxes. Moist monsoon winds.
