Tabuk, December 27, 2022, SPA -- The Saudi Press Agency (SPA) in Tabuk covered the weather conditions affecting the region during this period that witnessed snowfall at 1am on most mountains of Al-Lawz area. Areas covered with snow became a tourist attraction for Tabuk residents and visitors who arrived from various regions to enjoy the snow and the beauty of that area that witnessed snow. In a statement to SPA, director of the branch of the National Center of Meteorology in the Northern Region Alenizi stated that snowfall in the Northern Region of the Kingdom of Saudi Arabia, especially Al-Lawz Mountains and adjacent areas, depend on two main factors: the first is the extent of depth and movement of the polar depression and the availability of suitable moisture, as it often touches the northwestern areas of Alkan and Al-Lawz Mountain ", where a depression may deepen further south and affect the Hasmi mountains west of Tabuk. Its impact rarely reaches the south of Tabuk, where the Harrah Mountains are. The director added that the second factor is the extent of the freezing line's descent as polar depressions are accompanied by a drop in the tropopause level, thus the level of atmospheric layers falls. Weather enthusiasts look for some lines known as snowlines, such as the 540 line in the 500 mb layer and the 130 line in the 850 mb layer, he added. The director pointed out that the following factors give the likelihood of snow at the Earth's surface level: lines drawn in weather maps expressing how high or low the layer is, and thus how deep a depression can be, noting that the real scale is the zero Celsius temperature at any level, which determines the type of precipitation that occurs. --SPA 14:50 LOCAL TIME 11:50 GMT 0008 www.spa.gov.sa/w1832757
