The first five-year depression this year affects Egypt on Sunday 06-03-2022

Weather of Arabia - It is expected that Egypt will be affected on Sunday by a five-year depression that formed earlier on Friday over the Sahara Desert, and began to move inland from Libyan lands, and it is expected to affect Egypt on Sunday, bringing a warm, dusty and dry atmosphere in most areas.

A deep pentagonal depression centered in the north of the country

In the details, the country is affected by the first five-year depression this year, which is expected to be centered on Sunday afternoon to the north of Egypt, so that there is a sharp rise in temperatures so that they become higher than the usual rates by about 8-10 degrees Celsius, and weather conditions prevail in the fifties, so that the weather is warm and dry Dusty in most areas, and even relatively hot in southern Upper Egypt, and high clouds appear at intervals, accompanied by rain showers in random areas in the north of the country.

It is expected that the weather will be dusty in most major cities and governorates, but it will turn to become windy as well, especially the Sinai Peninsula and desert areas, where it is expected that winds will cause dust waves that may reach the extent of sandstorms in Sinai, which lead to a significant decrease and perhaps a lack of horizontal visibility. .

It is expected, God willing, that the five-year weather conditions will continue to affect Egypt at night, so that the weather will be very dusty in several areas, with a remarkably low range of horizontal visibility, including within the main cities, and the winds will be westerly to northwesterly active at speed, with strong gifts that lead to the continuation of Form dense waves of dust in the desert areas and Sinai.

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.
