WASM- WASM Regional Center is monitoring the forecast of a new polar wave surge towards the Eastern Mediterranean basin and the Kingdom, beginning after mid-month and continuing through the final third of February accompanied by renewed very cold conditions and large additional quantities of rain and precipitation, after the Kingdom received large quantities of rain during recent days that modified the current rainy season.
Rain is expected to continue intermittently during the coming days before the impact of the new polar wave after mid-month, making the current weather activity the longest in years.
West of the capital Amman recorded rainfall amounts exceeding 130 mm until Wednesday morning since the beginning of the current polar wave activity, bringing the total rainfall since the beginning of the season to 300 mm, which equals 60% of the entire rainy season, and the current rainy season improved after large quantities of rain that fell during recent days in most areas and forecasts for more rain during the coming days.
Rain continues intermittently in the coming days|
Rainy conditions and rain will continue "intermittently" during the coming days with the continued influx of atmospheric depressions over the Kingdom and the Eastern Mediterranean region, where heavy rains are renewed during Wednesday and Thursday, as well as during Saturday evening and the following Sunday and Monday on and off and intermittently with the Kingdom's continued exposure to the long-lasting polar wave and coinciding with very low temperatures approaching zero degrees Celsius and below in mountains and plains.
A strong polar storm is expected to surge towards Eastern Europe, Turkey and the Black Sea in the coming days, which increases the chances of renewed polar winds surging again towards the Eastern Mediterranean basin after mid-month.
A new polar wave looms on the horizon|
A new polar wave is expected to surge gradually towards the Eastern Mediterranean basin starting from the end of next week and intensify during the last week of February, which will renew heavy precipitation in various regions.
A strong high pressure zone is expected to persist over most areas of Europe coinciding with a strong polar storm in Eastern Europe, which causes polar winds to surge gradually towards the Eastern Mediterranean basin, especially with the coincidence and activity of Egyptian-African depressions, which will contribute to pushing polar winds southward more effectively, and this increases the probability of snow during the coming period.
The continuation of rain and precipitation during the recent period saved the current rainy season, especially with the seasonal performance exceeding in some central areas for the first time since the beginning of the current rainy season, and we expect further improvement to the rainy season, and we do not rule out that some areas will achieve their entire rainy season early during the coming period, especially the central region of the Kingdom.Intensification of the climate phenomenon "Seasonal Shifting"|
This phenomenon is called "Seasonal Shifting" and it is due to climate changes that affect the region, which have caused the intensification of this phenomenon in recent years, as it was found that the sum of more than 75% of rain in recent years has been delayed to the second half of the rainy season compared with 46% before climate changes.
This phenomenon also caused an increase in rainfall rates and a rise 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 clear 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 and recorded a seasonal increase of around 40-70% in most areas.
Jordan has not suffered during recent years from any shortage in rainfall quantities, but rather changes in the nature of the rainy seasons and their intensification and an increase in rainfall rates to more than 60%.
