LARGEST EVER OZONE LAYER HOLE CLOSES OVER ARCTIC



The largest hole over the Arctic region closes not due to the lockdown conducted by several countries for COVID-19, but due to some unusual atmospheric conditions as per reports. This hole was first observed in March this year, confirmed by the scientists.
“According to TIMES OF INDIA  ‘ European satellite system COPERNICUS has found that a record-breaking hole ever observed in the ozone layer over ARCTIC has closed ‘

This ozone hole was found by the scientist in the Copernicus satellite system early this year in spring was recorded the largest ever arctic ozone layer hole which can probably harm human civilization if it moved slightly towards the south, as per the scientists, but fortunately, it’s filled not for lesser pollution due to the lockdown for the pandemic called COVID-19 but for due to some unusual polar vortex in the atmosphere. The hole is massive its about 11 miles into the stratosphere, this kind of chemical ozone depletion was found nearly a decade ago as per reports.

WHAT IS POLAR VORTEX?

A polar vortex is usually found in earth’s both poles, which is basically formed in a large area due to low pressure and cold air, these vortexes existed but this weakened during summer and strengthen in the winter. The polar vortexes found in the arctic region are probably weaker due to the typical mountain ranges and nearby lands that are responsible for weather disturbances as compared to the southern poles/part.

The ozone layer is responsible for protecting us from the UV ( ultraviolet) rays/ radiations that are released by the sun along with sunlight, this layer is found probably 9 to 22 miles above from the sun. which usually depleted by human activities such as industrial chemical wastes like chlorine and bromine which migrates into the stratosphere from here ( earth ), which is alarming to humans.

Just like the Arctic ozone hole, the antarctic ozone hole in the southern hemisphere which is typically formed due to the chemical migration of chlorine and bromine in the stratosphere caused an ozone hole in the antarctic from last 35 years.
There is also good news too, that last year the ozone hole was at its smallest size since it was discovered according to the CAMS.

But it’s not sure that ozone will heal on its own for sure, humans too have to cooperate the process anyways moving to the current situation the ozone hole is recovering on its own in this way or that way.
