Arab Weather - In a special and distinctive paragraph with one of the scientific bodies in the field of weather and meteorology, the Jawk program hosted Dr. Jamal Al-Mousa , the Arab Weather Advisor, to talk about the fifties of winter and the most prominent weather phenomena in it , where Dr. Jamal Bidaya referred to the forties of winter that began with the beginning of the winter season Astronomer on the day of the winter solstice, which happened this year in the northern hemisphere on 12-21-2020 AD, and the forty days will last for 40 days, ending with the end of January.

 

The fortieth of winter - according to the climate records of the region - is considered the coldest period of winter, in which the lowest temperatures are recorded, and the amount of precipitation is about 30% of the general annual rate, and during which the region is affected by the largest number of frontal depressions, which are formed in the eastern sea The average white, that is, the winter fortieth is characterized by extreme weather systems.

 

After the fortieth of winter , the so-called Pentecostal Winter begins , which lasts 50 days, so that the day of the occurrence of the Spring Equinox ends at the end of March, and the Pentecostal is divided into four Sauds , each Saad lasting about 12 and a half days, and this is according to the Arab folklore that was in circulation in ancient times before the emergence of records Climatic.

 

The most prominent weather phenomena that occur in the winter 50's:

The first period of the winter fifties begins with what is called “ Saad al-Dhabeh ,” and the period of “Saad al-Dhabeh ” may be similar to the forty-day winter in terms of coldness and weather systems and the accompanying precipitation or snowfall. According to Jordan's climatic records, the incidence of snowstorms during January And February to 68%, and it happened in the winter of 91/92 that the Kingdom was exposed to 25 low atmospheres, and 18 snowy days, 11 of which were in February.

Dr. Jamal talked about the great snow that affected the Kingdom between 4-7 February 1950 AD, that is, during the period of Saad Al-Khath , which was due to a high-polar air mass, as the polar air masses are divided into two types: the polar air mass coming from Areas close to the pole between latitude 45 - 75 degrees north latitude, and high polar air masses , that is, from areas of the pole at high latitudes (between 75 - 90 degrees north latitude), which is the coldest mass that affected the Kingdom in 1950.

 

The reason for the change in rain and snow precipitation patterns in Jordan

Dr. Jamal talked about the phenomenon of global warming and climate change affecting the world, which caused a change in climate patterns in Jordan as well, as with the increase in the earth's temperature and the melting of ice in the poles, the global weather systems were affected, which affected the coldness of air masses that reach the White Sea In the Mediterranean, the atmospheric depressions that we are affected by in the region, the cold air masses may recede and are prevented from advancing to the eastern Mediterranean due to some weather systems, in addition to the El Nino and La Nina phenomena.

 

An example of this is what happened to the depression that was expected to carry snow to the Kingdom during Thursday and Friday, the strength of the depression was weakened due to the lack of adequate nutrition from the cold air from northern Europe, due to the multiplicity of depressions in those areas, there are depressions on the sea The Lions, the eastern Black Sea, central Europe, and over Britain, and depressions over the Atlantic Ocean west of Britain, all of these depressions worked to slow the progress and push of polar cold air towards the eastern Mediterranean, and thus weaken this expected depression.

 

Dr. Jamal also talked about some memories associated with some weather conditions and snowstorms that affected Jordan, some of the benefits of snowfall , the reasons behind some errors in weather forecasts, and some details about the forecast for the next depression.
