Weather of Arabia - Arab Weather provides you with the expected monthly weather forecast for the month of March 2022, and these are its features:

General situation :

1. Consecutive periods of cold and warmth, increase the chances of the spread of seasonal diseases.
2. The disintegration of the soil and the spacing of the chances of rain, foreshadowing the high chances and rates of recurring dust waves.
3. Great activity on the movement of surface winds.
4. Observing the affected parts of the Arabian Peninsula with the first rainy case this spring during the second third of March.
5. Cold to very cold weather is expected in many areas during the second and third week, especially between March 10-20.
6. Rain chances improve over Riyadh in the third week of the month

Special weather for each week

First week (1-7 March 2022)

General forecast for the week

• It is expected that the cold masses will accumulate on Turkey in conjunction with the impact of the tropical high on the atmosphere of the Arabian Peninsula, which weakened the jet currents and did not break them in the south, and this leads to the cold air and the upper influences being removed from most areas except northern Iraq.
• This results in high temperatures and dusty winds at times, with a chance of scattered rain in some areas. As for northern Iraq, it experiences cold and rainy winter conditions with snow falling over the mountains.

Week Two (March 8-14, 2022)

General forecast for the week

• During this period, it is expected that the cold air masses will rush towards the Arabian Peninsula, which means that the cold will intensify in many areas, convective clouds will also multiply, and the chances of rain will relatively improve, God willing, in some areas.
• The risk of raising dust as a result of surface wind activity and the presence of cumulus clouds continues.

Third week (March 15-21, 2022)

General forecast for the week

• During this period, it is expected that a cold upper influx will rush towards the north and center of the Arabian Peninsula, with the tropical highlands dominating the southeast of the Arabian Peninsula.
• It is expected that the first rainy spring event will arise with varying intensity, accompanied by the multiplication of thunderstorms in some areas and rainfall, God willing.
• And the weather remains cooler than usual in many areas.

Fourth week and rest of the month (22-31 March 2022)

General forecast for the week

• Atmospheric pressure is expected to rise for the first time in this way in several parts of the Arab Mashreq and Eastern Europe.
• This raises the temperatures in many areas, with a decrease in the intensity of rain at the expense of higher chances of dust and its intensity in some periods.

Climatic situation (for those interested and specialists):

During the past period, the atmospheric system in the northern hemisphere has witnessed the consequences of the behavior of the polar vortex, which is represented by a significant decrease in atmospheric pressure in the Arctic Circle (wind convergence system) that extends from high latitudes between 60 and 90 degrees north, which is related to the cohesion of the polar air in the higher latitudes. From the north of the globe, or what is known as the polar cell cohesion, and this would make weather events based on the system of leaks, shallow leakage and cutting systems (closed cold air masses), and it became understandable how such behavior is reflected on the weather in the Arab world. In it, the current winter season is considered one of the driest seasons in the countries of the Maghreb, and atmospheric depressions are largely immature in the Arab Mashreq.

What is new is that the polar dome is facing a dramatic change, a partial warming is expected in the stratosphere as a result of the vertical transfer of energy, which works to heat the stratosphere significantly and quickly, and the region is directly affected by the production of the polar cell in the north and the activity of the middle latitude cell ( Ferell cell ), and with expectations that no strong extremism will occur. In the values, and their fluctuation between light negative and moderate positive for each of the fluctuations of the ( AO & NAO ), it is expected that some refractions will occur in the movement of winds in the upper atmosphere, which leads to the rush of cold air masses south towards the European continent, including Parts of its east, God willing, especially in the second third of the month, but due to the presence of other factors that influence the formulation of weather patterns, especially those complex binary phenomena between water bodies and the atmosphere ( intraseasonal ), it is also expected that the prevailing weather pattern will be a large accumulation of cold Polarity is in the eastern European continent, but the air pattern may lack an ideal centering of the air altitude, extending excessively to the Scandinavian countries, which may make its base in the middle of the Mediterranean place A fiber that allows cold air to circulate towards it.

The same thing is the disruption of the polar vortex system ( disturbations in polar vortex ). The regions of the Arabian Peninsula usually benefit from the consequences of this in the form of a greater rush of Rossby waves towards the region. The polar vortex supports the cooling process and stimulates winter depressions on the Arabian Peninsula. So that the atmosphere in this period becomes very sensitive in the event that any air groove deepens in the atmosphere of the region, and it also interacts with the wet masses rushing from the Horn of Africa, so that the rains are usually more comprehensive and wide in light of the slow movement of the winter depressions as a result of the weakness of the western winds in the high layers of the atmosphere.

The Pacific Ocean

The tropical region of the Pacific Ocean is witnessing the dominance of the La Niña phenomenon, and it is expected that this phenomenon will continue to dominate during the month of March, and the following months, at a rate of up to 77%.

Climatically, this phenomenon is related to poor rain performance or the spacing and interruption of rain opportunities in general over the Arab Mashreq during the spring, and an increased activity of the hurricane season in the eastern Pacific Ocean and in the Atlantic Ocean, especially with the end of the spring season, but it is not possible to confirm these results based on a single weather phenomenon. , since the result, after the will of God, is the result of dozens of atmospheric variables.

God knows .
