The most important weather phenomena expected this month

The first and second week of December (December 8-14, 2021)

General forecast for the week

• It is expected that more intensification of the depressions of the middle latitudes on the European continent, in addition to a great activity in the strength of the Icelandic depression, so that the cold and rainy activity is focused on the central and western Mediterranean and the northern African continent.
• In the same period, the Siberian air altitude intensifies over parts of Russia and Central Asia, with its extension towards Iran and parts of northern Arabia, and this means stability on the weather, with a noticeable increase in the cold weather in parts of the east and south of the Kingdom at night.
• An activity of surface winds that raises dust and dust, which reduces horizontal visibility in parts of northern and eastern Saudi Arabia.

The second quadrant and the third week of December (December 15-21, 2021)

• Atmospheric systems are expected to gradually change during this period, as atmospheric pressure rises on the whole of the old continent, which leads to the rush of cold air towards the eastern basin of the Mediterranean, while it is expected that the subtropical air altitude will weaken from the north of the Arabian Peninsula, paving the way for improvement In the chances of the arrival of relatively cold air masses towards Egypt and northwestern Arabia, coinciding with the activity of the humid tropical masses around the region.
• This leads to a relative improvement in the chances of rain in the north and west of Saudi Arabia, and it may affect parts of the central region of the Kingdom.
• Chances of thunderstorms rising in the area and warnings of torrential rain in some areas.
• The activity of surface winds that raises dust and dust, which reduces horizontal visibility in the front of the rainy thunder clouds.

The third and fourth week of December (December 22-30, 2021)

General forecast for the week

• It is expected that the atmospheric height will deepen on the European continent, especially the western parts of it, with a complete receding of the influence of the semi-tropical atmospheric height on the Arabian Peninsula, which will give way to the extension of some cold upper air grooves sometimes from the north through Iraq and Iran, and at other times from the gateway to the Levant and the eastern basin of As a result, large parts of the Arabian Peninsula are affected by unstable weather conditions, which result in the multiplication of clouds and rainfall, God willing.
• High chances of torrential rain in some areas.
• Cooler weather during the hours of the night, dawn and early morning, so that it becomes less than its normal rates in large parts of the region.
• Surface wind activity that provokes some dust and dirt.
