predicate | For these reasons, the temperature in Turaif at noon is cooler than Jizan at dawn in the winter season

Weather of Arabia - A series of tweets tweeted by Dr. Abdullah Al-Misnad, in which he explained the reason for the great variation in temperatures in the winter season (December, January, February) in the Kingdom, saying that Saudi Arabia is a vast and vast country, and its area is more than 2 million km2, and it consists It consists of 13 regions, each region the size of a country or more, praise be to God, and extends from latitude 16 degrees north to latitude 32 degrees north, with a total of 16 degrees latitude.

Al-Misnad said that this is not repeated except in a few countries, and this geographical extension necessarily affects the angle of incidence of the sun's rays on each transverse circle, and then the great temperature variation between north and south until you find the difference between the minimum temperature in Turaif and Jizan in the winter season up to about 21 degrees Celsius.

He also emphasized that this variation in temperatures is very large, and even the noon time in Tarif is colder than dawn in Jizan. On the other hand, its topography varies in height from a few meters above sea level in some coastal cities and governorates to about 3000 m in Jabal Al-Souda in Abha. The two factors met: the height above sea level, and the fact that the site is located in the far north of Saudi Arabia. Here, the temperature drops to record the lowest degree in Saudi Arabia and even in the Arabian Peninsula.

This represents the summit of Jabal al-Lawz in the Midian mountain range, northwest of Tabuk, with a height of 2549 m. It can be said, according to digital historical statistics, that the coldest Saudi governorates in winter are located in the north of Al-Jawf region, represented by the governorates of Tarif and Qurayyat.

This is followed by other northern cities and governorates, which are in the coldest order first: Arar, then Hail, then Sakaka, then Tabuk, then Rafha. The reason for the coldness of Turaif and Qurayyat in winter is their location in the far north of Saudi Arabia, close to the influences of the cold northern air masses.

In addition, this location makes the angle of the sun's rays falling on them the largest in the winter season in Saudi Arabia. While the warmest region in winter is the Jizan region represented by the capital Jizan, then the Makkah Al-Mukarramah region represented by the Jeddah Governorate, then Makkah. In general, in winter, the further north we go, the lower the temperature.

The higher we rise above sea level, the lower the temperature, and the closer we get to the coast, the higher the temperature is relatively, especially the western coast, and specifically the middle and southern ones. The Hijaz and Sarawat mountains act as a buffer against the incursion of cold air masses coming from the north and northeast.

Therefore, we find the geographical places that lie to the west of the Sarawat Mountains warmer than the places that lie to the east of them in general.. This and God knows best.
