Arab weather - The last depression, classified as a fourth degree, brought abundant amounts of rain to most of the governorates of the Kingdom, praise be to God. The central regions, including Amman, were most affected by the goodness of the air depression, as the winter square came to an end in 2021/2022 and this coincided with the end of the effects of the depression Fourth-degree weather, the statistical rain data issued by the Jordanian Meteorological Department showed a remarkable improvement in rain performance, despite the fact that the cumulative rain amounts are still below average in most regions of the Kingdom. We review with you in this detailed report, which sheds light on some important aspects of the performance of the rainy season in Jordan.
Rain performance is defined as the percentage of the cumulative amount of rain that is supposed to fall until a certain date, as the data of the Jordan Meteorological Department showed that the percentage of the performance of the rainy season reached about 75% compared to the amounts of rain that are supposed to fall for this time of year. general.
It is clear from the same data and values that there is a noticeable improvement in the rain performance in most regions of the Kingdom, especially the central ones. This is evident from the recording of Al-Salt’s presumed rainfall rates to date, as the Salt station recorded a performance of 128% over the assumed rate, with 345 mm of rain, which is the most It has been raining since the start of the rainy season.
The rain performance of the capital, Amman, has been very good until now, as most of the stations in the capital approached their usual rates, especially the meteorological station located in Al-Hussein Gardens, which has exceeded its assumed rainfall rate to date, and whose performance has so far reached 107%, at a rate of 277 mm, compared to 258 mm as an assumed total based on previous years’ rates. It is worth noting that the areas in which dams are concentrated in Jordan are located in the north and center of the Kingdom.
Referring to the statistical report, it shows that there is a noticeable difference in rain performance between the governorates of the Kingdom, while the northern and central regions recorded a very good rain performance, but most of the southern and eastern regions still suffer from modest rain performance until the moment, and by this we mean weak rainy cases in recent regions The mentioned, and this is evident from the data received from meteorological stations in the southern and eastern regions, for example, the rain performance in Karak and Shobak was about 64%, while in Tafila 81%, while the rain performance decreased significantly in Wadi Musa, recording modest values of about 22 %.
The results of analyzing the same data indicate that the areas in which dams are concentrated in Jordan (northern and central of the Kingdom) have significantly improved rain performance, praise be to God.
When comparing what has been achieved about the actual amount of rain falling in this rainy season with the entire annual average (which ends in the month of May), we find that to date, no region has reached its annual average, and this is considered normal if approximately four remain in the rainy season. Months, however, the Aqaba Airport monitoring station (King Hussein International Airport) exceeded 123%, meaning that more than the seasonal average has fallen in the last period, which is a promising value.
The central regions are also considered the closest to their seasonal average by about 53%, meaning that the last period of rain fell equivalent to half of what should fall in the same region throughout the entire rainy season. Ras Munif in Ajloun has a seasonal average of 586.8 mm.
There is no doubt that Jordan and several regions in the Levant suffered from a rain fall at the beginning of the season, as the region was affected by the first classified air depression at the end of the autumn season, and this is considered too late if we compare the weather conditions this year with its predecessors in the climatic archives of Jordan and the region, and it continued Weakness in the rainy season during the first half of the square.
Perhaps the second half of the quadrangle has restored its balance to the rainy season, praise be to God, after the Kingdom was exposed to three air depressions, two of which were classified as advanced degrees, due to the way the air systems and air masses from the Atlantic Ocean, the North Pole and the European continent were distributed, which led to the push of cold air masses. In the upper layers of the atmosphere towards eastern and southeastern Europe and the Balkan basin, and these last mentioned areas are considered the most important source of effective atmospheric depressions affecting the Kingdom.
And the mercy of God Almighty remains above everything, and we ask the Almighty to grant us relief.
