Why does Australia have less ozone?

The stratospheric ozone layer absorbs the biologically damaging wavelengths of ultraviolet (UV) rays but in the 1970s, Australia’s ozone layer was severely thinned as a consequence of heavy use of ozone-depleting, substances such as chloroflurocarbons (CFCs) and hydro-chloroflurocarbons (HCFCs).

Is there less ozone in Australia?

More about ozone layer depletion

Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. Data collected in the upper atmosphere have shown that there has been a general thinning of the ozone layer over most of the globe.

Why does Australia get more UV light than other parts of the world?

Ozone in the atmosphere can absorb ultraviolet light, which stops the light from reaching Earth’s surface, so people absorb less of it. Australia has less ozone than other places, like Brazil, and this is why Australia gets more ultraviolet light.

Why is there less ozone in the Southern Hemisphere?

In the Southern Hemisphere, the South Pole is part of avery large land mass (Antarctica) that is completely surrounded by ocean. … This chlorine and bromine activation then leads to rapid ozone loss when sunlight returns to Antarctica in September and October of each year, which then results in the Antarctic ozone hole.

Why is the sun so bad in Australia?

The problem with Australia is that the continent receives higher UV radiation levels than Europe. “Being located close to the ozone hole over the Antarctic means that much higher, more severe levels of UV radiation get through to ground level,” says Dr Hasanien.

Which country has the worst ozone layer?

The Antarctic ozone hole is an area of the Antarctic stratosphere in which the recent ozone levels have dropped to as low as 33 percent of their pre-1975 values.

Why does NZ have a hole in the ozone layer?

The very strong vortex that forms over the Antarctic in winter blocks the poleward flow of ozone, leading to the springtime increase in ozone over New Zealand at the same time as it isolates polar ozone and primes it for the annual Antarctic ozone hole.

Why is the ozone hole above Australia?

The stratospheric ozone layer absorbs the biologically damaging wavelengths of ultraviolet (UV) rays but in the 1970s, Australia’s ozone layer was severely thinned as a consequence of heavy use of ozone-depleting, substances such as chloroflurocarbons (CFCs) and hydro-chloroflurocarbons (HCFCs).

Is the sun brighter in Australia?

Look at the bright red spots in the Pacific, mid-Atlantic and Australia where irradiance (the power of solar radiation) is highest. … Australia receives much more solar radiation than California or even the Mediterranean famed for its sunny summers and beautiful beaches.

Is Australia humid or dry?

Due to the huge size of the country, Australia has serveral different climate zones. The northern section of Australia has a more tropical influenced climate, hot and humid in the summer, and quite warm and dry in the winter, while the southern parts are cooler with mild summers and cool, sometimes rainy winters.

Why is the largest ozone hole over Antarctica?

A new NASA video highlights the giant ozone hole that opened over Antarctica this year. A cold Southern Hemisphere winter, and possible effects of global warming, have caused the hole to grow to its 13th-largest extent since 1979.

Why is there more ozone depletion over Antarctica?

Antarctic ozone hole

The Antarctic is much colder than the rest of the planet and experiences consistent strong winds. The Antarctic ozone hole develops in August and dissipates in late November when warmer weather and ozone rich air from outside the polar vortex disrupts the chemical reactions causing ozone depletion.

Where is ozone the thickest?

The location of the ozone layer

The amount of ozone above a location on the Earth varies naturally with latitude, season, and from day-to-day. Under normal circumstances, the ozone layer is thickest over the poles and thinnest around the equator.

Is Australia closer to the equator?
