15:18 - Alarm ozone, in the sky over the Arctic regions has been found enormous an empty one of that layer of gas that it protect to us from the harmful beams of the sun for our skin, those ultraviolet ones. Ozone to March is come down to levels minimums in our hemisphere. The survey in the atmosphere of this event has been executed from the satellite of the Agency Spaces them European Envisat. No worry in Italy, above all for who already from now begins to go in beach. As Maximum Carlotti of the CNR has explained us
Which consequences on the zones of the earth that are found under this hole of ozone?
The satellitari measures supplied from ESA show that the hole has been taken place over an area enclosed within the Arctic polar circle, therefore over zones practically depopulated of the planet. Human beings presents in the interested zone however are protect from the cancellation ultrvioletta (left to leak from the ozone absence) from the clothing that is used normally in the polar zones.
Which the repercussions on Italy?
For analogy with the evolution of the hole of the ozone that verification every year on the Antarctic continent (in the months between september and November) puo' to assume a thinning of the layer of ozone to the high latitudes (Russia, Alaska, Scandinavia) after that the dissolved polar vortex sara' (presumablly within meta' May). The entita' of this monitorata thinning sara' with continuita' from the instruments of satellite ENVISAT of the Agency He spaces them European but much minor regarding the currently measured hole previews itself that sara' however. In the event of meaningful impoverishments of the ozone layer the populations of the zones interested must have the shrewdness to wear glance at them when exposed to the solar cancellation. Alle latitudes of Italy does not expect us no consequent impoverishment to this hole and therefore no increase of the ultraviolet cancellation.
The forecasts: it is destined to increase or it could also be shrunk?
The mechanism of formation and evolution of the hole of ozone is by now very famous perche' verification every year on the antarctic continent in the period between september and November (spring in the hemisphere south). This anomalous hole on the hemisphere north is consequence of temperatures particularly lowlands that they have taken place this year during the Arctic winter. The hole is destined to disappear when the temperatures will go back (presumablly within meta' May). The scientific question regards the eccezionalita' of the conditions that have lead to the formation of the hole and if draft of a shunting line statistics or if is destined to repeat perche' consequence of climatic changes us in action Is percio' important to currently continue the measurements from the space with piu' possibly powerful instruments of those in use.
The causes and because own in this period has taken place the drastic thinning of the ozone layer.
Perche' is during the winter that the temperatures of the stratosphere come down to levels that they provoke, on one side the formation of the polar vortex and from the other the condensation of some gas present in stratosphere that real clouds go to form solid particles () on which chemical reactions happen details that are to the origin of the formation of the hole of ozone.
