Weather of Arabia - The latest weather forecasts extracted from the outputs of the so-called computer simulations indicate expectations of a widening impact of the rainy weather affecting the Kingdom to include new areas during Sunday and Monday 24 and 25 April 2022. The outputs herald that the capital, Riyadh, may fall under the influence of The rainy condition, God willing.
In the details, the Kingdom is increasingly affected by a state of atmospheric instability resulting from the convergence of an extension of a shallow air depression that extends into the Kingdom of Saudi Arabia called the Red Sea depression and an air mass less hot in the upper air layers accompanying an upper air depression in addition to the fact that this confluence coincides with the flow of moisture in the layers The weather is different from tropical regions, and this results in an expansion of the rainy condition on Sunday and Monday to include many parts of the Kingdom, God willing, but at the same time, it is expected that the intensity of the rainy condition will decline in other regions, which are many.
And according to what is indicated by the outputs of the computer modeling developed by Arab Weather , the chance seems weak overall, but it is possible for some marine graduations to flow on some coastal areas of Makkah at dawn and Sunday morning, and chances of rain continue on random parts of the center and north of the Kingdom on Sunday morning, represented by parts From Madinah, Hail, Al-Qassim, Hafr Al-Batin, the northern border, the north of the Riyadh region administratively, and some of the southwestern highlands of the Kingdom. As usual, in such spring cases, cumulus clouds increase in intensity during the afternoon hours and the area of rain expands to include the southwestern highlands of the Kingdom and its eastern slopes. It also includes Medina, especially the eastern parts of it and the northern and western parts of the administrative region of Riyadh, Hail and Qassim, all the way to parts of Al-Jawf and the borders. In the north, however, it is believed that cumulus formations will be in these areas in a less severe way compared to Saturday.
Towards the evening hours and the night of Sunday / Monday, weather forecasters in the Arab Weather Center monitor the possibility of an extension of the rainy thunder clouds to include several parts of the Riyadh region administratively and may extend to the capital during the late hours of the night, in addition to the northern eastern region, including Hafar Al-Batin, at the same time. Chances of rain are gradually declining in most of the northern and northwestern regions of the Kingdom, God willing. It is expected that these thunder clouds will be accompanied by random rains, but they are sometimes heavy and accompanied by lightning and thunder, in addition to that they are often preceded by a great activity in wind speed that may cause the formation of local dust storms, and the fear of low or near-lack of vision. horizontal in some areas.
According to the latest weather readings, the indicators indicate the depth of the depression in the upper layers of the Kingdom’s airspace on Monday 25-4-2022, so that the air pressure in the middle layers of the atmosphere shifts from the eastern parts of the Kingdom, and as a result, the effect of the rainy condition expands on large parts of the country. The Eastern Province may affect Dammam and the Riyadh region, and the capital, Riyadh, will be among the areas covered by thunderstorms on Monday, where thunder showers of rain fall at times, causing a rise in the water level in the streets, in conjunction with the continuation of thunderstorms in large parts of the southwestern, northern and northwestern sectors. However, the chances of rain are expected to decline in most areas of Hail, Qassim and Madinah on Monday, with the chance of some rain falling on those areas, but less severe than in the past days.
It is believed that the situation will be strong in some areas during Sunday and Monday in terms of weather and weather instability, as many data indicate an increase in the chances of the occurrence of so-called sudden torrential rain in random parts of the center and north of the Kingdom on Sunday, and strong weather disturbances remain on the day Monday on parts of the Riyadh region administratively, the north of the eastern region, and parts of Al-Jawf and the northern borders. This condition is also associated with thick cumulus thunderstorms, which means that there is a high chance of the occurrence of the so-called severe downward winds that lead to the occurrence of temporary sandstorms, in addition to the occurrence of lightning and thunderbolts that are sometimes dangerous.
According to the analyzes, it is expected that the unstable weather conditions will continue to affect parts of the Kingdom on Tuesday 4/26-2022, but on areas less extensive than these days, as the eastern and northeastern regions of the Kingdom are concentrated, with rain chances remaining in the capital, Riyadh. Specialists in the Arab Weather Center believe that there will be a new depth of the upper air depression by the end of this week, so that the patch of thunderstorms will expand again to include large parts of the Kingdom, God willing. The outputs of analyzes and computer simulation data for weather forecasts until the time of writing this report fluctuate in their forecasts for the areas covered by the new weather disturbances expected at the end of this week. Light on more details in ascending order whenever needed, God willing.
As for the scientific reasons for the improvement of the air system in the Arabian Peninsula, God willing, the specialists in the Arab Weather Center say that a weakness in the north polar vortex system led, thank God, to the flow of less hot air towards the south, i.e. towards the region, in conjunction with the control of a system of pressure The high air over the middle of the Mediterranean Sea and the west of the Asian continent, which prompted the deepening of the air depression in the upper layers of the atmosphere towards the northeastern parts of the Arabian Peninsula, by the union of both the polar and subtropical jet streams. As a result of the harassment of the above-mentioned air altitude, this increased the same and continuous weather condition, God willing, until the end of the holy month at least, with clear support from tropical water vapor, praise be to God.
