Arab Weather - Sinan Khalaf - As we enter the marking season, questions about the initial expectations of the season increase in terms of rain precipitation or in terms of temperatures and cold waves, and from this point of view, the Arab Weather teams issued the seasonal bulletin (months 11-12-1 .. November and December and January) for the year 2022 AD, accompanied by an explanatory video in addition to several aerial maps:

The specialists at the Arab Weather Center monitor the expected behavior of the atmosphere during the next few months, which is directly affected by climatic factors that somehow reflect its circulation. Where the Arctic region is still witnessing an expansion in the extent of snow, the expansion of the snow cover in October over Siberia is statistically related to the weakening of the stratospheric polar vortex early in winter, and the control of atmospheric heights more than usual in many Arctic regions, which is the same This is felt by computer modeling of the simulation of the atmosphere.
There is no doubt that the Arab world is directly affected by the consequences of this, as it is expected that the distribution of air masses in the next two months (i.e. November and December) will be affected by the regions of the north and west of the European continent, all the way to the Maghreb countries in succession of cold and rainy depressions, which may It turns to snowy during the month of December, while the regions of the Levant and Egypt are affected by warmer air currents than usual on many occasions separated by the approach of air depressions that are mostly sub-systems, while parts of the Arabian Peninsula are expected to benefit from more mature weather systems During the second half of the marking season as a result of approaching cold grooves sometimes to the gate of the central Mediterranean and Egypt, and at other times to the eastern gate of the Arabian Peninsula.
Despite the high correlation coefficient in the aforementioned relationship, which usually means polar cold accumulation in the western European continent and sometimes eastern Canada to the eastern United States of America, the formulation of weather patterns is controlled by many complex factors, from the prevalence of the phenomenon of La Niña and Represented by the low surface temperatures of the waters of the tropical part of the Pacific Ocean, and the complex binary phenomena between water bodies and the atmosphere that undergo a sudden change sometimes during the season, which is scientifically called intraseasonal, such as the locations and intensity of the Madden and Julian waves (MJO). And whose effects vary from time to time according to other weather elements and indicators that are prevalent in the world.
And the specialists in the Arab Weather Center look with optimism at the beginning of next year, which is believed to bring with it drastic changes at the level of weather systems, which is represented by the control of air heights over important and wide areas of the west and central European continent, so that the eastern regions alternate at that time. And the middle of the Mediterranean Sea with cold air masses, and the regions of Iraq, the Levant, Egypt, northern Saudi Arabia, and perhaps parts of the Arabian Gulf were affected by more mature depressions.
As a general summary, it is expected that the autumn season will bring rains higher than the average in the countries of the Maghreb, which may be interspersed with snow on the highlands, while the regions of the eastern Mediterranean basin will be under the influence of sub-cases in general, but it is offset by a return to winter during the month of January , while it is believed that it will be the opposite in the Maghreb, where the atmosphere is more stable and warmer, God willing.
God knows.
