Al-Shaker explains: 3 scientific reasons behind the weak rainfall and lack of weather events

Mohammed Al-Shaker, CEO of Arab Weather, said that the weakness of the current rainy season and the absence of effective weather events is due to several interconnected scientific reasons that affect weather systems in the region.

Al-Shaker explained that the first reason is the occurrence of a large diversion in the polar jet stream towards the south of the European continent, the central Mediterranean and North Africa, which led to the concentration of low-pressure systems in those areas and their accompanying heavy rain and heavy snowfall, while in contrast, strong high-pressure systems pushed towards the eastern Mediterranean and the Kingdom, preventing the arrival of rain systems.

He added that the second reason is due to the development of the “La Niña” phenomenon in the Pacific Ocean, which is a cooling of the tropical waters off the coast of Peru, leading to a decrease in sea surface temperature below normal levels. This has been clearly reflected in the region through the intensification of high-pressure systems that act as a barrier preventing low-pressure systems from advancing towards the eastern Mediterranean.

The third reason, according to Al-Shaker, is an unprecedented cooling of the Arabian Sea. This year, the sea is experiencing its strongest cooling since 1998, with surface temperatures dropping to rare levels due to changes in wind patterns and regional weather systems. Al-Shaker emphasized that this cooling is not limited to the sea itself, but extends its impact to the climate of the Arabian Peninsula, weakening the performance of the autumn season, which relies heavily on the temperature of the Arabian Sea as a primary source of humidity.
