Why is Australian sun so strong?

During summer, the Earth’s orbit brings Australia closer to the sun (as compared to Europe during its summer), resulting in an additional 7% solar UV intensity. Coupled with our clearer atmospheric conditions, this means that Australians are exposed to up to 15% more UV than Europeans.

Is the sun brighter in Australia?

This is from Solar irradiance and it gives a much more accurate picture of insolation in Australia. It’s still very high – make no mistake, Australia’s got some powerful sunshine. But no more so than southern Africa or areas in the northern hemisphere at the same latitude.

What country has the strongest sun?

Australia – where the Sun hits the hardest

  • 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 the sun stronger in New Zealand than Australia?

In terms of energy, the sun is stronger in Australia due to it being closer to the equator. But in terms of UV light which causes sunburn, it is stronger in New Zealand due to a thinner ozone layer, and less pollution (clearer air).

Why is the sun stronger in the Southern Hemisphere?

The southern hemisphere tends to have more UV exposure because of the ozone hole, a seasonal depletion of the ozone layer centered on the South Pole.

Why is there no ozone layer in 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 Australia hotter than America?

Is the Australian summer hotter than an American? They cannot be compared. Remember that both Australia and the USA are massive countries.

Is the sun stronger in Arizona?

Arizona is Close to the Equator and has Higher Elevation

Another reason it’s location makes it so hot is it’s proximity to the equator. It’s about 2,300 miles from the equator, which is close enough to mean it receives a lot of the sun’s energy, especially at the end of the year.

Is the sun stronger in Hawaii?

Due to the Hawaiian Island’s proximity to the equator, the suns rays are much stronger that what you might experience at home. (Unless of course, your home is also near the equator.)

Is the sun stronger in Colorado?

The higher up in altitude that you get, the stronger the sun becomes. And so Colorado, you know we’re probably somewhere around 20 to maybe 35 percent stronger sun, or stronger UV radiation than what you have at sea-level. Also the air is more dry here.

Why is there no ozone layer in New Zealand?

Ozone concentrations measured over New Zealand are not affected directly by the ozone hole, which lies over Antarctica each spring. The ozone hole is an area where the ozone layer is less than 220 DU, caused mostly by ozone-depleting substances emitted by people.

Why is the NZ sun so strong?

In high summer, the sunshine in New Zealand is really strong. … Earth’s orbit takes it closer to the sun during the southern summer than during the northern summer. There is less pollution in the southern-hemisphere to block the UV rays. The sun’s burning strength is measured by the UV index.

Where on earth has the highest UV?

Peak UV should occur within the tropics (high sun, low ozone), at a high altitude site, in the Southern Hemisphere. Near the Tropic of Capricorn, overhead Sun occurs during the period when the Earth- Sun separation is a minimum.

Why is UV so high in Australia?

During summer, the Earth’s orbit brings Australia closer to the sun (as compared to Europe during its summer), resulting in an additional 7% solar UV intensity. Coupled with our clearer atmospheric conditions, this means that Australians are exposed to up to 15% more UV than Europeans.

How dangerous is the sun in Australia?

Sun exposure is the cause of around 99% of non-melanoma skin cancers and 95% of melanomas in Australia.

Is the sun getting stronger?

The Sun is becoming increasingly hotter (or more luminous) with time. … Astronomers estimate that the Sun’s luminosity will increase by about 6% every billion years. This increase might seem slight, but it will render Earth inhospitable to life in about 1.1 billion years. The planet will be too hot to support life.
