WASM- The impact of the polar wave on the Kingdom's atmosphere continues during the coming days and for a long period of time, with low temperatures persisting and intermittent precipitation continuing, which will be in the form of snowfall over the Kingdom's high mountains, particularly in the southern and northern regions.
The impact of the polar wave is expected to intensify again during the middle of next week gradually, and is expected to result in more heavy precipitation and snow accumulation on the high mountains.
Precipitation recedes from Thursday evening until Saturday morning|
Precipitation is expected to continue until Saturday morning but with an expected decline in intensity over the western regions of the Kingdom, falling intermittently and continuing mixed with snow in the mountainous areas and in the form of snow showers on high mountains exceeding 1200 meters above sea level, temporarily dropping to 1000 meters on Friday evening and affecting some of Oman's high peaks.
Very cold atmosphere on Saturday and Sunday with frost and freezing alert|
Weather is expected to improve relatively on Saturday and Sunday but the atmosphere will remain very cold with continued cloud cover and limited chances of rain in various areas or light snow showers, with freezing and frost formation expected during night and morning hours in mountains and plains.
Renewal of heavy precipitation mid and end of next week|
As a result of the continued impact of the polar wave on the Kingdom's atmosphere, another atmospheric depression is expected on Monday next and heavy precipitation is expected to renew across different regions of the Kingdom, particularly the western areas of the country, which will be in the form of snowfall on high mountains, and these precipitation is expected to continue but intermittently until the end of next week at least.
Monitoring the renewal of polar winds surge towards the eastern Mediterranean and the Kingdom mid-month|
As a result of the continued presence of a strong and unusual atmospheric high pressure over most areas of Europe and even its far northern regions, this will result in the formation of a strong polar storm over eastern Europe and even Turkey and the Black Sea region, which will lead to the renewal and intensification of the polar wave's impact at a later time from the end of next week until after mid-month, and WASM regional center will issue the details progressively.
No signs of polar wave retreat during medium-range periods|
Due to the nature of the atmosphere and its unusual circulation, the flow of polar winds is expected to continue for a long period and possibly in a rare occurrence towards the eastern Mediterranean basin and northern Arabian Peninsula during the coming weeks with no clear indicators of this polar wave retreating, which will greatly increase the demand for fuel for heating purposes.
As a result of these polar winds and their long period of impact, this will greatly affect the agricultural sector and delay agricultural crops from their usual schedules, and will also lead to large amounts of rain or heavy snow accumulation on high mountains, which exposes many areas to valley flooding, dam flooding and significant impact on infrastructure.
This atmospheric arrangement resulted from strong and sharp activity of the Siberian high pressure and it is the first activity this season but it came at a very late time, causing a continuous flow of very cold polar winds towards eastern Europe, Russia, southeastern Europe and even the eastern Mediterranean, and as a result of its coincidence with unusual activity of Atlantic storms, this will expose most areas of Europe and many areas of North Africa to warmer periods and less rain and confine polar winds only towards the eastern Mediterranean basin within a rare and unusual atmospheric arrangement.
This atmospheric arrangement is expected to continue until mid-spring at least, which increases the chance that this season will end with large rainfall and precipitation rates despite weak seasonal performance until 31-1-2025 by about 15% below the usual rate in many areas, where many areas did not exceed more than 35% of the rainy season which is supposed to achieve 50%.
Intensification of the climate phenomenon "Seasonal Shifting"|
This phenomenon is called "Seasonal Shifting" and it is due to climate changes affecting the region, which have caused the intensification of this phenomenon in recent years, where it was found that more than 75% of rainfall in recent years has been delayed to the second half of the rainy season compared to 46% before climate changes.
This phenomenon has also caused an increase in rainfall rates and an increase in the rate of extreme winter or snow storms, and an increase in the chance of very large amounts of rain falling in shorter time periods, and this phenomenon was very evident in the 2022-2023 season, where more than 90% of the rainy season fell in some areas during the second half of that season and rain continued until mid-June, registering a seasonal increase of about 40-70% in most areas.
Jordan has not suffered in recent years from any shortage in rainfall amounts, but rather changes in the nature of rainy seasons, their intensification and an increase in rainfall rates to more than 60%.
