The Centre-North hit by rain, the South free

A North focused by rains introduced by Atlantic currents filled with humidity and a South left free by those self same currents, that are unable to succeed in it, whereas temperatures are in all places greater than common. That is the meteorological state of affairs during which Italy at the moment finds itself and which, in accordance with specialists, after at this time’s truce may come up once more within the subsequent few days with the identical strategies, and with rains that may hit rivers and lakes during which the extent of the water is already excessive.

“This era of the yr is characterised by Atlantic currents: depressions that deepen over Northern Europe and push in direction of the Mediterranean”, observes Silvio Davolio of the Institute of Atmospheric and Local weather Sciences of the Nationwide Analysis Council. The origin of the moisture-laden currents is within the low stress space which is producing cyclones which can be set to accentuate over the British Isles. The southern reaches of this space of ​​low atmospheric stress “don’t deepen into the Mediterranean, nor are Mediterranean cyclones forming”, observes the Cnr-Isac professional. After having entered from the West by means of the Strait of Gibraltar, the truth is, the Atlantic currents filled with humidity rise till they attain Italy within the Apennines space between northern Tuscany, Emilia Romagna and Liguria.

“The penetration of a trough linked to an Atlantic disturbance is a typical phenomenon of the interval between October and November”, observes Lorenzo Giovannini, professor of Meteorology on the College of Trento. “Regardless of this being a traditional state of affairs as a kind of phenomenon, October thirtieth was undoubtedly a really intense autumn occasion”, he added. Particularly, “the injury within the province of Parma was on account of very stationary convective bands, linked to the orography of the Apennines between Tuscany and Liguria, and which dumped very intense rainfall in the identical space, inflicting injury”.

The state of affairs “is destined to repeat itself within the coming days”, observe each specialists. “Within the night time between Thursday and Friday the same disturbance is anticipated in the identical areas” and, continues Giovannini, “hydrogeological issues can’t be dominated out because the soils are saturated and the river ranges have already suffered a flood wave”. Additionally for Davolio, the traits of the meteorological state of affairs are such that the important points will proceed to concern the identical areas already affected “in fluctuating phases, during which in the future of unhealthy climate alternates with a break, relying on the frequency of the cyclones that generate the humid currents”.
