Jordan: In conjunction with the control of the Siberian Highlands over the region... the radioactive fog is a guest on the desert and plains and affects neighborhoods of the capital

Weather of Arabia - Radiation Fog was a guest in the region of the eastern plains and the eastern desert. As a result of the high values of relative humidity in the low and near layers of the earth's surface to saturation values in those areas, which are followed by the plains of the governorates of Mafraq, Zarqa, east and south of the capital, and this includes Zizia, Queen Alia International Airport and Airport Road.

The aforementioned areas are characterized by the rapid cooling of the air after it is still in the late hours of the night and early morning (which raises the chances of fog formation in it compared to other areas such as mountain heights), and in the event that water vapor is available and the air temperature reaches the dew point. Without it, fog forms. These weather conditions, in addition to others such as high atmospheric pressure, declining wind speed, and the absence of significant cloud cover, are among the necessary conditions for the formation of radiation fog in these areas, which is sometimes dense and extends for long hours. It sometimes extends to some central central regions of the Kingdom.

And it works sometimes to obstruct movement on the roads, as well as perhaps air navigation. According to the official report released on the Amman Civil Airport station in the Marka area, the horizontal vision range was only 50 meters! At 8 am on Thursday 12-29-2022.

This type of fog in these areas, which usually affects with stable atmospheres, differs from advection and upslope fog that affects high areas in the Kingdom, including the heights of the capital, in the presence of an air depression and is associated with the formation of clouds in contact with the surface of the earth.
