Bilad al-Sham: A Khamasini air depression is approaching the region for the next few days, which imposes significant weather fluctuations on the atmosphere..Details and recommendations

Weather of Arabia - The outputs of analyzes and computer simulation data of weather forecasts indicate expectations of the movement of the five-year depression centered (during the preparation of the report) over the Libyan territories eastward towards the eastern basin of the Mediterranean Sea, and this depression imposes significant weather fluctuations between a significant rise in temperatures followed by a decrease perceptible to heat.

In the details, the Khamasinyi depression will move on Monday towards Turkey, which means the transmission of the five-year weather conditions to the Levant, including Jordan, so the Arab weather expects that the five-year weather will prevail in most regions, and the weather will be hot, dry and dusty unevenly in different regions, with the emergence of high clouds.

As for at night, the five-year weather conditions continue in various regions with the early hours of the night, while the atmosphere tends to moderate with the late night hours, and large amounts of medium and high clouds appear, and there is a weak chance of “mud” rain points in limited parts.

Why are the pentagonal depressions formed at this time of the year?

The Khamsiniyah depressions are known as thermal depressions that usually form in the spring in the northern part of the continent of Africa (in the Sahara), and move parallel to the coast of the Mediterranean towards the eastern basin of the Mediterranean and the Levant region. Thermal depression is defined as a depression resulting from the intense heating of the Earth’s surface, which results in a decrease in the density of the air above it, so it rises up and the pressure decreases, and the air begins to gather from areas of high pressure towards areas of low pressure, and an upward movement is formed that is in a narrow vertical space.

The five-year depressions are formed in the Sahara and North Africa in this period of the year (the spring period) as a result of the decrease in atmospheric pressure due to the high temperature there compared to the temperature of the Mediterranean water, which becomes cold after the winter season. These depressions push the surface winds laden with dust from the Sahara desert towards the east.

The Khamasin depressions are usually accompanied by the Khamasin winds, which are mostly southwesterly winds, which are dry and warm and come from the Sahara Desert, loaded with tons of dust and raised dust, and move quickly towards areas of the eastern Mediterranean, such as Egypt, the Levant, Iraq, and the Arabian Peninsula region. Temperatures and dusty conditions will reduce visibility.
