“Winter returns”. With this title he refers to his forecast of the next few days, saying it comes cold with rains but the possibility of snowfall is small and the only snow is expected to fall on the mountains of the Aegean islands. “After the intense rainy weather that we expect to prevail today and tomorrow until about noon, there is a strong winter weather setting with its main characteristics local stormy northwards towards the Aegean side, the vertical fall of mercury and also the frost,” Clearchos Marousakis noted. CORVERSE This change is due to ‘the displacement of polar gas from northern northeastern Europe to our country’. “It is perfectly normal for the time when we are in and we can even say that it is abnormal that we have been living in the last several days with mercury reaching or even exceeding 20 degrees locally. To make this more understandable, it is sufficient to note that an indicative maximum temperature for early February is about 11 to 13 degrees. With this change we will be driven about and indicatively as a maximum temperature value close to 8 to 12 degrees” it complements. “Ambient precipitations are a combination of several atmospheric parameters. One of these is the available relative humidity at the various levels of the atmosphere. Also an important role is played by temperature differences in height in the atmosphere that leads to the development of instability in the atmosphere combined with other parameters such as, for example, wind profile,” he notes. CORVERSE He adds: “To explain this more simply, we note that these polar air masses even reach our country, have no sources of moisture available from the surface, i.e. they pass over land rather than valuable marine areas.” Concerning the possibility of snowing, it explains: “Since there is no significant potential cause, we expect the polar gas mass to get any moisture from the Aegean sea. So whatever phenomena we expect in areas that “see” towards the Aegean or where topography will favour e.g. mountain – semi-mountain volumes near the Aegean Sea.” “It is worth noting that it is very likely to snow even with low intensity on our Aegean islands, when at the same time high mountains of the mainland will enjoy many hours of sunshine despite the chilly cold and strong frost. And that’s all because the polar gas mass will find the moisture from the Aegean Sea to bring about the phenomena. So summarizing the closer to the sea of our Aegean, the more the chances of low intensity snowfalls even low. The further away from the Aegean Sea, the more hours of sunshine but an intense cold escort” he adds. Then he talks about strong northers that will even reach all 8 Beauforts: “The collision of polar gas masses with warmer ones that will meet along their way will result in the development of a strong barograde (pressure differential). From the course of motion of the polar gas mass it becomes evident that the area with the development of a larger barograde will be the Aegean. There the north will reach tensions the storm levels (7-8 Beaufort). As we move further west, the effect of the north will decline,” he notes. The risks from the new bad weather “In descending order the risks of this change follow, i.e. starting with the most important we will lead to the least important. This assessment takes into account both the intensity and duration of the phenomenon. a. Ice b. Northerly c. Temperature retreat d. Phenomena (rain, snow etc.). Finally, it is worth noting that cold and frost will have a long duration and this should be taken into account mainly by our farmers in order to take appropriate measures to prevent their production,” he concludes.
Weather: Rains until Tuesday and then chilly cold with strong northies – A few snows in the Aegean mountains
