Monday December 21 - the date of the winter solstice and the beginning of the winter square

Weather of Arabia - Monday, December 21, 2020 marks the date of the winter solstice in the northern hemisphere, including the Arab world, based on astronomical calculations.

On 12/21/2020, the sun will be completely perpendicular to the Tropic of Capricorn, south of the equator, and this is considered the most remote point that the sun reaches in the sky of the earth to the south, as that day is the first day of winter in astronomical terms, and the shortest day in the day and the longest at night in the northern half Globe over the whole year.

Since ancient times, humans have been able to distinguish this day before the existence of modern technology and even before the order of days and months, as is happening in our current time. Humans have noticed since ancient times that the sun begins after this day to ascend to the north in its apparent movement, as the length of the night decreases and the length of the day gradually increases. So that night and day are equal on 20 March next, that is, the time of the vernal equinox.

The relationship of the winter solstice to the square

The winter solstice day is considered the beginning of what is called "winter square" in the Levant and many Arab countries, where this date was linked in the memories and experiences of grandparents and their minds with the advent of cold and heavier rains throughout the year and for forty days, which is consistent with modern science where the corner works Which the Earth revolves around after this date on the increase in the number and activity of depressions that affect the Levant and the Arabian Peninsula during this period.

The path of depressions becomes suitable for the region to be more affected by them, and this statement is confirmed by the climate records, as the Al-Murabaniyah period witnesses the lowest rates of temperature recorded throughout the year in the region, and this period usually witnesses the highest rates of rain.

Reason for naming square this name

The designation of the winter square with this name came as a result of the number of days of this period in terms of astronomy (approximately 40 days) starting from the time of the winter solstice, until the end of January, but on the ground, this period may be less or more than that according to regulations Prevailing weather.

Entering Al-Murabaniah does not always mean intense rain and hail
The site notes that entering the astronomical area within the so-called Al-Murabaniyah does not necessarily mean the arrival of storms and rains directly or the intensity of rain and cold as soon as this period begins, as years have already come in which Al-Murabaniyah was dry and with low rain rates, and there have also been years that Al-Murabbaniyah began with atmospheres. Stable that later changed to cold winters during the 40-day period.
