Arabia Weather - The regions of the northern half of the Earth, including the Kingdom of Saudi Arabia, entered the autumn season on the first day of September and continues until the end of November. During this period, gradual changes begin to occur in the distribution of weather systems, and this is reflected in a slow decrease in temperatures, God willing, in Most areas.
The west of the Kingdom of Saudi Arabia will be affected in the coming days, especially on Wednesday 9/6/2023, by the heat dome phenomenon, which is caused by the positioning of the seasonal Arabian Ridge over the region, leading to a severe heat wave in some western parts.
The phenomenon of a heat dome is known as pushing hot air close to the surface of the Earth, thus preventing the return of heat in the atmosphere, so it remains trapped in the lower layers within the framework of this heat dome, leading to increased periods of sunshine and increased temperatures and humidity together.
The dominance of this thermal dome over the west of the Kingdom is due to the distribution of weather systems in the northern hemisphere, where it is expected that the upper lows, accompanied by less hot air, will rush towards central Europe and reach the central Mediterranean, and this will necessarily lead to an intensification of the upper air high. Over Egypt, western Saudi Arabia, and the Levant.
The impact of the extremely hot air mass on the west of the Kingdom causes temperatures to rise beyond their usual levels by more than 8-10 degrees Celsius in some parts.
This heat wave directly affects most parts of the Medina region, especially Tihama and Mecca, reaching nearly 50 degrees Celsius in the Holy Capital, especially on Wednesday.
