The most important weather phenomena expected this month

Special weather condition for each week:

First week (1-7 December) 2021:

• Rain: below average
• Temperatures: about averages.
• Flood Chance: Low.
• Snow chance: none.
• Description of air systems:
  
  • The month begins with the Kingdom being affected by a sub-air system (an extension of an air depression) that brings with it some rain showers on the first day of the month for some areas, with a significant decrease in temperatures compared to the end of November. After that, the Kingdom is temporarily affected by an extension of the Siberian air rise, so that the cold southeast winds activate and a relatively cold and stable atmosphere prevails during the day, and cold at night hours. Later during this period, it is expected that the Kingdom will be affected again by a new sub-air system (an extension of an air depression or perhaps a state of atmospheric instability) so that the chances of rain will renew.

Second week (December 8-14) 2021:

• Rain: below average
• Temperatures: Turn to warmer than average.
• Flood Chance: Low.
• Snow chance: none.
• Description of air systems:
  
  • The Kingdom continues to be affected by sub-systems of weather, either in the form of extensions of rapid air depressions or cases of atmospheric instability, so that opportunities increase from time to time for some rainfall. Separating between these cases, the Kingdom is affected by the extension of the Siberian air rise, so that the dry southeast winds activate, which increases the feeling of coldness, especially at night.

Third week (December 15-21) 2021:

• Rain: about average
• Temperatures: Turn cooler than average.
• Flood Chance: Medium.
• Snow chance: Low.
• Description of air systems:
  
  • It is expected that the region, including the Kingdom, will continue to be affected by secondary weather conditions, most likely one of which will be at the beginning of this period in the form of a state of atmospheric instability that increases the chance of thunderstorms from rain, and thus increases the chances of torrential rain in some areas. During the end of this period, it is expected that an air mass will gradually form over the whole of the European continent, with expectations that the first major cold air mass will rush towards the region so that Jordan and the Levant will be affected by the first comprehensive air depression and may be of an advanced classification that brings with it abundant rain, God willing, and a decrease Remarkably high temperatures.

Fourth week (December 22-31) 2021:

• Rain: above average
• Temperatures: Colder than average.
• Flood Chance: High.
• Snow chance: Medium on high mountains in the Levant
• Description of air systems:
  
  • The depth of the air rise is increasing on the European continent, especially the western part of it, so that this leads to the rush of several cold air masses towards the Middle East, including the Levant, and as a result the temperatures drop significantly from the usual rates. The weather in this period is characterized by great cold and more than it is accustomed to. It is not excluded during this period that the Kingdom will also be affected by an air depression (which may be classified as an advanced degree), bringing with it abundant rains to large parts of the Middle East, including Jordan and the Levant, with winter phenomena in general.

How to issue monthly bulletins

The issuance of these forecasts depends on studying the behavior of temperature and atmospheric pressure in the northern hemisphere, including the atmosphere and major water bodies, and integrating those forecasts with global monitoring centers, to come up with the highest possible forecast.

Arab weather experts in the Scientific Research and Development Department have developed scientific methods that are considered the first of their kind in the Arab world and the world, relying on artificial intelligence in forecasts for the coming months, by developing complex mathematical algorithms and equations to detect the behavior of the atmosphere and correct long-range weather forecasts.

In contrast to the daily weather forecast, these bulletins focus on listing the general weather during a month, where the aim is to know the deviation of rainfall amounts and temperatures from their general rates. Many meteorologists in the world are busy trying to decipher the mystery of making accurate seasonal forecasts by conducting many researches in this regard, in which the Arab Weather team participates in part.

The desired benefit of the quarterly bulletins lies in assisting the various sectors in the early planning for the fall and winter alike, especially the agricultural sector, which builds its agricultural plans on these indicators that sometimes help to reap and achieve profits by exploiting this information, in addition to many other sectors that Benefit from these forecasts, such as the commercial sectors, the apparel sector, the energy sector and others.

Note: It is strictly forbidden to transfer this information, data, and the weather forecast, and publish it on social media and others, and/or dispose of it in any way without taking the prior and written consent of Arab Weather, under penalty of legal accountability.
