Weather of Arabia - The autumn transitional period is characterized by the abundance of weather and temperature fluctuations that are clear and tangible in two close periods of time, and it is possible to delve into the details of the reins of affairs more in order to explain the reason for the large number of weather fluctuations in this period.
With the spring season, air and temperature fluctuations increase as a result of the conflict that occurs between the air masses coming from different sources, and in the spring the Red Sea depression becomes active. Red and land heat in the Arabian Peninsula and Sudan, and the Red Sea depression is a sub-extension of its original habitat, and it is the Sudanese thermal depression. The Red Sea depression causes high temperatures and dry weather in many regions.
In the same period, the season of activity of the Khamseen depressions begins, as it is a type of thermal depression, which is active in the spring, and the Khamseen depressions usually arise in the Algerian desert east of the Atlas Mountains, but the locations of their formation vary. Libyan lands.
This type of depression is formed as a result of the high heating of the land (the surface of the earth). In the spring, temperatures begin to rise in the north of the African continent, as the surface of the earth heats up. Because of the difference in specific temperature between land and water, the water surface of the Mediterranean remains cold, and the land becomes warmer. Thus, the air on land begins to expand, its weight decreases, and the atmospheric pressure decreases, announcing the birth of a five-year depression in the Sahara desert.
In the forefront of the five-year depressions, the five-year weather conditions prevail, represented by dry, warm (or hot) and dusty weather, but the five-year depression soon moves away, and an air mass with lower temperatures rushes behind it, causing a sharp drop in temperature in a period of time that may not exceed 24 hours Sometimes, the Khamseen depressions are among the most prominent causes of temperature fluctuations in Jordan's climate during spring.
At the same time, the flow of less hot air masses continues towards the eastern regions of the European continent and loses a large part of its coolness upon reaching the Mediterranean waters, thus affecting the countries of the eastern basin in the form of spring masses mostly, and this depends on the coldness of the air mass coming towards the waters, so it cannot be certain that it is It will always be spring.
And here begins the conflict between the air masses coming from the east of the European continent and those coming from the Arabian Peninsula, the Red Sea and North Africa, and thus the temperature fluctuations increase remarkably and the chances of seasonal diseases such as colds and seasonal flu rise.
