AGAIN TWO BARIC STRUCTURES CONNECTED ON THE WEEKEND
Dear friends of RIWMAG and METEOEVENTI, the holiday season is approaching and the last weekend before Christmas is just around the corner.
From a meteorological point of view, the European scenario is divided into two: to the west high pressure prevails, to the east the low pressure. There are, Therefore, the conditions for wind generation thanks to the pressure difference between these two structures. Let's see together what lies ahead over the weekend.
The whole weekend will be characterized by the scenario described above, but the pressure gradient will be greater on the southern coasts of the Bel Paese and it is there that the wind will give a pre-Christmas weekend worthy of note.
Pressure (Geopotential Height Black isoline) temperature (in color) scheduled for the night between Saturday and Sunday. On the southern part of Italy there will be the most pronounced clash between the two meteorological structures highlighted in the figure. (source ECMWF www.ecmwf.int and elaborated by METEOEVENTI).
