MEDIUM-TERM CLIMATE TREND, DECEMBER 13-20 – Important baric reorganization on a European scale. Increase in pressure and geopotentials between the Mediterranean and central states, highlighted by positive anomalies, or values above the average, in continuity with the anomalies in Russia. At the same time, negative anomalies will persist in Western Europe. At this stage for Italy a more stable and drier climate with rainfall often below average and temperatures above average, particularly between 15 and 18 December.

LONG TERM CLIMATE TREND, DECEMBER 21-27 – drop in geopotentials in the Mediterranean and Italy, even below the average between the western Mediterranean and Spain. Meanwhile, geopotentials and above-average pressures will be confirmed not only in Russia, but also in northern Europe and especially in most of the North Pole. At this stage, we look forward to a more dynamic time in Italy., particularly in Centrosud where the rain could be more incisive. Also, cold setbacks from the East cannot be ruled out, particularly on the Adriatic side, just before Christmas.

LONG TERM TREND UNTIL NEW YEAR 2021 – Negative anomalies in the western Mediterranean tend to be absorbed by entering the neutral field. Positive anomalies are still confirmed in Russia. At this stage, very little can still be said about Italy, which could still be characterized by some rainy Atlantic passage, with greater participation from the western regions. Important updates to follow!
