Scientific analysis | How did the behavior of the atmosphere over the Arctic contribute to the absence of heat waves in the Kingdom?
Arabia Weather - Weather forecasters at the “Arab Weather” Center said that the outputs of weather maps up to the moment indicate that heat waves will continue to move away from the Kingdom’s atmosphere, and experts in Arabia Weather explained that the behavior of the atmosphere up to the moment and since the Kingdom was affected by the last heat wave last June. It forces hot air masses not to advance further into the Kingdom’s atmosphere.
The behavior of the atmosphere over the North Pole helps in the absence of heat waves in the Kingdom
In a study conducted by weather specialists at the Arab Weather Center on the behavior of the atmosphere over the North Pole and the movement of air masses from the beginning of last July until the present moment, a calm was observed in the movement of air pressures over the North Pole, specifically the Greenland region, and the Arctic Oscillation recorded wave values. Mild to neutral, as this oscillation often allows the continued movement and activity of the polar jet stream around the North Pole and thus linked to the movement of cold air masses around the North Pole, as shown in this chart from NOAA:
North Pole AO oscillation
North Atlantic Oscillation (NAO).
Weather forecasters at the Arab Weather Center said that the movement of air pressures over the North Pole contributed to the continued undulation of the polar jet stream and its non-concentration in a specific region in the northern hemisphere, as studies indicate that the undulation of the polar jet stream contributes to the continued flow of cold air masses from The North Pole and projecting it eastward towards Russia and eastern Europe, thus benefiting from the upper refractions, which reach the eastern Mediterranean region and the Levant in the form of air masses with lower temperatures and act as a counter to the tropical air high stationed over the Arabian Peninsula.
Heat waves in Europe and the control of the heat dome over North African countries play an important role in the absence of heat waves in the Kingdom
Specialists in “Arab Weather” say that the weather systems in the northern hemisphere are linked to each other, as the behavior of the atmosphere in low latitude regions is closely linked to the behavior of the atmosphere in high latitude regions and the regions of northern Europe and the Arctic, and with reference to what We talked about it previously. We find that the weather conditions are forcing, up to the moment, the African air high to be stationed continuously over the north of the African continent and to continue directing hot air masses towards the European continent. This is due to the undulating behavior of the polar jet stream, which allows the continued penetration of the African high air towards western and central Europe, leaving the area It is open to the cold air masses heading towards the north and northeast of the European continent and later heading towards southeastern Europe and the eastern Mediterranean.
