2020 and 2011 weather anomalies due to ozone layer depletion – Terra & Poli

Arctic ozone depletion causes atmospheric anomalies in our hemisphere, and could be one of the main causes of anomalies recorded in the spring of 2020 and in 2011. suggesting a direct link between ozone depletion and vortex evolution changes Polarity is an international study led by Thomas Peter of ETH Zurich and published in Nature Geoscience.

When we talk about the ozone hole, we generally think of the great thinning found in the upper layers of the atmosphere that lie above Antarctica, in the Antarctic, but another critical region even if less well known is that above the North Pole, in the North Pillar . Ozone is a gas that is found at very high altitudes and plays an essential role in protecting life on Earth because it is able to block out most of the dangerous radiation that arrives from the sun. Gas envelopes the planet, but there are two types at the poles. of wormholes (more visible in the south) also due to human pollution that shrink and expand dynamically during seasons, and its size has long been suspected to somehow determine some meteorological anomaly.

By entering data on changes in the Arctic ozone layer into mathematical models, the researchers observed associations between ozone depletion peaks and anomalous hot and dry springs in central and northern Europe and in Russia and Siberia in 2020 and 2011. According to the study, less Arctic ozone is present. , and therefore less filtering of solar ultraviolet rays, leading to greater cooling of the stratosphere and thus reducing the ‘strength’ of the polar vortex, the large mass of cold. Air circulates in the polar region. Polar vortex interactions will have direct meteorological consequences with what is being recorded across the entire hemisphere.
