However, just as suddenly as it formed, the gash has now healed. These waves drive movements of air through the upper atmosphere akin to weather systems that we experience in the lower atmosphere, but much bigger in scale.In a typical year, these waves travel upward from the mid-latitude lower atmosphere to disrupt the circumpolar winds that swirl around the Arctic. “The waves stir the white paint, higher amounts of ozone in the mid-latitudes, with the red paint or low ozone contained by the strong jet stream circling around the pole.”The mixing has a second effect, which is to warm the Arctic air. "The game is not totally over. The hole is still nowhere near as worrisome as its southern counterpart and doesn't currently threaten human health.

These waves drive movements of air through the upper atmosphere akin to weather systems that we experience in the lower atmosphere, but much bigger in scale.In a typical year, these waves travel upward from the mid-latitude lower atmosphere to disrupt the circumpolar winds that swirl around the Arctic. Researchers were recently awarded rapid-turnaround project grants to explore how COVID-19 stay-at-home measures are affecting the environment and how the environment is affecting the virus's spread. A space-based laser that measures clouds and small atmospheric particles called aerosols has provided a unique view of the massive Saharan dust plume that crossed the North Atlantic Ocean in June. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control total global production and consumption of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge and technological information. Satellite data from NASA shows the ozone layer above the Arctic in March 2019 compared to March 2020, when the hole formed.
An analysis of satellite observations show that ozone levels reached their lowest point on March 12 at 205 Dobson units.While such low levels are rare, they are not unprecedented. The blue and purple colors are The This summer, Siberia has seen potentially record-breaking temperatures as high as 100.4 degrees Fahrenheit (20 degrees Celsius) as well as wildfires burning on a massive scale across the countryside. This image made available by NASA shows a map of a hole in the ozone layer over Antarctica on Sunday, Oct. 20, 2019. unless otherwise noted. over the Antarctic pole. ozone for March 2020. Chlorofluorocarbons are long-lived compounds that take decades to break down, and scientists expect stratospheric ozone levels to recover to 1980 levels by mid-century.NASA researchers prefer the term “depletion” over the Arctic, since despite the ozone layer’s record low this year, the ozone loss is still much less than the annual ozone “hole” that occurs over Antarctica in September and October during Southern Hemisphere spring. (2020, March 17). “But we do know that if we hadn’t stopped putting chlorofluorocarbons into the atmosphere because of the Montreal Protocol, the Arctic depletion this year would have been much worse.”Since 2000, levels of chlorofluorocarbons and other man-made ozone-depleting substances have measurably decreased in the atmosphere and continue to do so. These clouds enable the release of chlorine for ozone-depleting reactions. In addition, the stratosphere remained cold, leading to the formation of polar stratospheric clouds, which allowed chemical reactions to release reactive forms of chlorine and cause ozone depletion.“We don’t know what caused the wave dynamics to be weak this year,” Newman said. Ozone-depleting chlorine and bromine come from chlorofluorocarbons and halons, the chemically active forms of chlorine and bromine derived from man-made compounds that are now banned by the Montreal Protocol.
By late March, these balloons measured a 90% drop in ozone at an altitude of 18 kilometres, which is right in the heart of the ozone layer. NASA Ozone Watch This animation shows daily ozone levels observed by NOAA satellite from January 1-April 18, 2020. NASA Ozone Watch ... with these clouds to eat away at the ozone layer. The warmer temperatures then make conditions unfavorable for the formation of polar stratospheric clouds. “The waves stir the white paint, higher amounts of ozone in the mid-latitudes, with the red paint or low ozone contained by the strong jet stream circling around the pole.”The mixing has a second effect, which is to warm the Arctic air. First, they bring with them ozone from other parts of the stratosphere, replenishing the reservoir over the Arctic.“Think of it like having a red-paint dollop, low ozone over the North Pole, in a white bucket of paint,” Newman said. Arctic stratospheric ozone reached its record low level of 205 Dobson units, shown in blue and turquoise, on March 12, 2020. Credit: NASA’s Goddard Space Flight Center.
