Weather of Arabia - the European continent is preparing during the next few days to face a severe cold wave that will be the strongest for this season, as weather forecasts indicate an eruption of a very cold air mass of polar origin and Siberian characteristics to the west, unusually towards the whole continent at the end of the week.<h3 style=";text-align:left;direction:ltr"> Eastern European rally at the end of the week</h3> As we enter the month of February, the atmospheric enters its height in the northern hemisphere, where the amount of cooling for all layers of the atmosphere reaches its peak before we enter the month of March, which is the beginning of the spring season in meteorology. What accompanies this great activity in the atmospheric movement is the sharp rippling in the jet stream, which leads to the separation of the polar air masses and their rapid movement south, which will happen during the next two days with the separation of a huge polar air mass and its movement towards western Siberia and the formation of a strong and wide air height located over the countries of Scandinavia And the far north of Europe pushed it west.<h3 style=";text-align:left;direction:ltr"></h3> The usual weather patterns in the northern hemisphere begin to change in the middle of the current week, with the cycle of atmospheric movement entering its peak coinciding with the expansion of an air height over Scandinavia, the Arctic and the eastern Atlantic Ocean, the main air mass separating from the Arctic and moving around this high air towards western Russia and then It moves unusually westward directly towards the east of the European continent and later reaches its west. <img alt="" src="/sites/default/files/uploads-2020/arabiaWeather-map-2021-02-07--14_06_45.jpg" style="width: 800px; height: 532px;" /> Among the features of the separate polar mass that will move towards Europe is that it is of the dry continental polar type, with Siberian characteristics, and it is the coldest type of air mass on the face of the globe, bringing with it freezing weather, ice and severe frosts throughout Europe for several continuous days. As a result of this polar eruption, temperatures in all European capitals drop below zero degrees Celsius, and perhaps below 20 degrees Celsius in some storms in the east of the continent.<h3 style=";text-align:left;direction:ltr"> The warming of the stratosphere during the month of January may be one of the reasons for the separation of the entire polar mass from its habitat on more than one occasion this winter</h3> The attached map represents a distribution of the temperature of the stratosphere during the month of January, as it clearly shows the amount of heating in this layer above the North Pole specifically, as this heating prevents the cohesion of the polar air mass over the pole and its dispersion far south to farther latitudes. <img alt="" src="/sites/default/files/uploads-2020/polar-vortex-splitting-weather-winter-united-states-europe-major-warming-event-february-2021.png-nggid0522151-ngg0dyn-700x700x100-00f0w010c010r110f110r010t010.png" style="width: 699px; height: 600px;" /> Because of this warming, there is a hypothesis about the effect of this phenomenon indirectly about the expected polar eruption on Europe in conjunction with our entry into the peak of the atmospheric activity and activity in the eastern returns in February.
