What Time Is It In Brisbane?


What Time Is It In Brisbane

Why are Melbourne and Brisbane in different time zones?

DAYLIGHT saving begins in many states around the country tomorrow morning, and no wonder Australians are about to get confused. From 2am on Sunday, the country will officially have five different time zones. Designed to make the most of the summer months, residents from New South Wales, Victoria, South Australia, Tasmania, and the Australian Capital Territory will turn their clock forward one hour.

  1. This means you won’t be woken by the morning sunlight anymore as we gain more daylight in our evenings.
  2. However as QLD, the Northern Territory and Western Australia are not followers of daylight saving, the country is set to go into a time zone confusion.
  3. Think of it like this.
  4. Residents of Sydney, Melbourne, Hobart and Canberra will now be half an hour ahead of Adelaide, one hour ahead of Brisbane, one and a half hours ahead of Darwin and three hours ahead of Perth.

Confused much? The differing time zones is due to the size of our land mass. Australia is usually divided up into three separate time zones, however with daylight saving this becomes five. Queensland recognises Australian Eastern Standard Time (AEST), but New South Wales (except Broken Hill), Victoria, Tasmania, and the Australian Capital Territory recognise Australian Eastern Daylight Time (AEDT).

South Australia and the town of Broken Hill in western New South Wales follow Australian Central Daylight Time (ACDT), the Northern Territory follows Australian Central Standard Time (ACST) and Western Australia stays on Australian Western Standard Time (AWST). Phew. To add to the confusion, Queensland, who rejected a move to daylight saving 22 years ago, is considering a partial move to daylight saving suggesting that those in either southeast Queensland or southern Queensland, who are close to the NSW border, move their clocks forward one hour during summer, leaving the rest of the state operating under AEST.

So what does this mean for our sleep? Moving our clocks forward means we lose one hour of sleep, but you can be prepared for it. Dr Doug McEvoy, an Australian sleep physician from the Sleep Health Foundation, says the best thing you can do is follow the sun.

  1. Over the next week you should get as much bright light exposure first thing in the morning to help reset the body clock.
  2. This may mean having breakfast on your patio or not wearing sunglasses on your way to work,” he says.
  3. The time change will also mean that it may be more difficult for some to get to sleep at their usual time.

“Preparing for sleep is really important, no caffeine, tea or chocolate before bed. Get into a relaxed frame of mind before going to bed and keep iPad’s and televisions out of the bedroom.” Interestingly, it is the 35 to 50 year old age groups that are the most vulnerable to the daylight saving shift due to their tendency to be “short sleepers”, he says.

Christmas Island is a dot in the Indian Ocean, located 2600km north-west of Perth, Western Australia. Even though it is an Australian Territory, its closest neighbour is Java, 360km away.

Why is Australia close to the sun?

Beachgoers in Darwin, Australia, have given up their bikinis and bare chests. Instead, they shield their skin from the blistering sun with long-sleeved shirts and hide their faces under floppy hats. Ultraviolet (UV) radiation in Australia is so intense that on a sunny day, a fair-skinned person can get a sunburn in less than fifteen minutes.

  1. Australia’s unusually harsh sunshine results mainly from its location in the Southern Hemisphere.
  2. The elliptical orbit of the Earth places the Southern Hemisphere closer to the sun during its summer months than the Northern Hemisphere during its summer.
  3. This means that the summer sun in Australia is 7 to 10 percent stronger than similar latitudes in the Northern Hemisphere.

Air currents high in the atmosphere sometimes bring ozone-depleted air from Antarctica’s ozone hole to Australia, letting even more UV through. And Australia’s sunny weather and relatively pollution-free air provide little additional protection from harmful UV rays.

  1. With the highest skin cancer rates in the world, Australians have reason to pay attention to the factors that modulate UV light, such as cloud cover, ozone, and aerosols.
  2. Australians have already experienced an increase in sun intensity from ozone depletion, resulting from human-generated emissions of chlorofluorocarbons.

Scientists are concerned that climate change could have further effects on UV radiation levels by changing the amounts of aerosols suspended in the atmosphere. Dust, smoke, pollution, and other small particles can scatter solar radiation back into space, decreasing the sun’s intensity.

But in certain situations, they can also increase UV levels. Aerosols absorb solar and thermal radiation, contributing to warmer temperatures and climate change. Scientists are not sure which of these processes wins, because they know little about how UV and aerosols interact. To sort this out, a group of scientists from Australia and the United States decided to study how aerosols affect UV radiation.

Calvin, University Corporation for Atmospheric Research) Aerosol interactions Frank Mills, a research scientist at the Australian National University, moved to Australia from California five years ago with the goal of exploring the relationship between climate change, aerosols, and UV radiation.

  1. Other researchers have suggested that climate change may lead to warmer, dryer weather that could increase smoke and dust aerosols.
  2. Mills wondered how changing aerosol levels would affect UV rays and whether aerosol type would make a difference.
  3. An atmospheric physicist, Mills saw the lack of information on the interactions between aerosols and UV as a snarl of connections waiting to be untangled.

“Climate change is likely to induce changes in cloud cover, aerosol abundance, and wind patterns, and these changes could have effects on surface UV levels,” Mills said. “But there hasn’t been any research as to whether that’s true or not.” Mills decided to start with a basic question: how do different aerosol types affect UV radiation? From his previous work, Mills knew that a variety of data on aerosols was available.

But finding accurate UV data would be more difficult. “At the time that I came to Australia, the UV data that existed were of sporadic quality and limited geographic range,” Mills said. Then in 2004, the Australian Bureau of Meteorology set up full-spectrum UV monitoring stations at Darwin, on Australia’s northern coast, and Alice Springs, a desert town 1,500 kilometers (932 miles) south of Darwin.

With the UV data gap filled, Mills needed a dust and smoke expert. He recruited research scientist Olga Kalashnikova from NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. Kalashnikova had helped develop a way to separate dust from other aerosol types using the Multi-Angle Imaging Spectroradiometer (MISR) instrument on the NASA Terra satellite.

  • The idea of connecting aerosol properties with variations in UV radiation intrigued her, because she wanted to know how aerosols could affect climate.
  • But knowing that aerosols come in many shapes and sizes, Kalashnikova also knew that different aerosol types have very different effects on sunlight.
  • Understanding those wavelength-dependent differences was crucial for studying climate change.

Australia’s low levels of aerosols primarily come from controlled fires in the north and occasional dust storms in central and southern Australia. The burning season usually peaks in November; December represents the beginning of the rainy season. These images show aerosol optical depth (AOD) in November and December 2004; orange and red indicate higher AOD, while blue and green indicate lower levels.

(Courtesy O. Kalashnikova, from Terra MISR) Effects on UV light Previous studies had shown that some aerosols, such as the pollutants that linger over big cities, reduce the UV reaching the ground, absorbing it or scattering it back into space. But aerosols include a diverse collection of materials, including a variety of airborne particles from the gases and particulate matter in pollution to natural dusts and smoke from wildfires.

Each of those particles has different properties. So Mills and Kalashnikova planned to explore how different aerosol types affect solar radiation, using MISR aerosol data from NASA’s Atmospheric Science Data Center (ASDC), together with the Australian UV measurements.

Serendipitously, the two sites the Australian Bureau of Meteorology chose for their measurements were home to completely different aerosol conditions. Darwin, on Australia’s northern coast, is occasionally blanketed in smoke from nearby wildfires. Alice Springs experiences periodic dust storms, which turn the sky a hazy orange.

The different aerosol conditions provided a natural laboratory in which to compare the UV effects of dust and smoke. The aerosol conditions at Darwin and Alice Springs were also well suited to satellite study, since MISR could differentiate between dust and non-dust aerosols.

Alashnikova said, “Unlike other satellites, MISR can see the way light scatters from many different angles.” This unique capability meant that MISR could measure not only aerosol depth, but also determine what type of aerosol was present from the particle shape. Most aerosol particles, including smoke, are spherical.

But mineral dusts, essentially minuscule pieces of rock, have an irregular shape. By examining the way that an aerosol layer scatters multiple beams of light, Kalashnikova used the MISR sensors to determine whether those layers are made up of chunky, irregular dust particles, or smooth, spherical smoke.

  • And this allowed her to compare how each aerosol type affected sunlight.
  • Smoke in the skies Mills and Kalashnikova first examined smoke effects on UV.
  • They identified wildfires using thermal anomaly data from the NASA Moderate Resolution Imaging Spectroradiometer (MODIS), and identified the smokiest days using MODIS aerosol optical depth measurements.

Then they compared UV measurements from the clearest and haziest days in Darwin over the yearlong study period, finding that dense smoke coverage reduced the amount of UV light reaching the ground by as much as 50 percent. However, the effect depended on wavelength.

  1. The UV radiation that reaches the Earth contains wavelengths just shorter than the visible spectrum of light, and is classified into UV-A and UV-B.
  2. Lower-energy UV-A has a longer wavelength, while higher-energy UV-B has a shorter wavelength.
  3. In Darwin, smoke aerosols reduced UV-B radiation as much as 40 to 50 percent on the smokiest days.

The same amount of smoke reduced UV-A only 20 to 25 percent. While the team had expected that UV-A effects would be smaller, they were surprised at the magnitude of the difference. Kalashnikova said, “It’s very important to know how different wavelengths are affected.” UV-B light is responsible for sunburns and is linked to the development of certain skin cancers.

  • Longer wavelength UV-A penetrates further into the skin and can damage collagen, connective tissue that provides skin with structure and elasticity.
  • Next, Mills and Kalashnikova hoped to compare their smoke results to dust events over the Australian desert.
  • However, in Alice Springs, the team encountered a problem.

“We couldn’t find any good dust events,” Kalashnikova said. Using MISR, Kalashnikova had searched for plumes of aerosols that had dust-like scattering properties, but even with a year of data to draw from, they found only a few days showing moderate dust storms over Alice Springs.

A big part of Australia is covered by desert,” Kalashnikova said. “In theory you would expect a lot of dust there.” But even though the deserts around Alice Springs spewed up the occasional dust storm, very little dust reached their study site. “In our study, not much dust was transported outside of smaller dusty regions,” Kalashnikova said.

The dearth of dust storms proved a setback in comparing the two aerosol types, but Kalashnikova said that it was a fascinating finding in itself. “It’s interesting because Australia was thought to produce a lot of dust,” she said. However, the study showed that, unlike Africa, where huge desert storms regularly send plumes of mineral dust thousands of miles across the Atlantic Ocean, Australian dust storms may often be confined to smaller areas.

  • Even without major dust events to draw from, the Alice Springs data suggested that dust aerosols were not as opaque to UV as smoke was.
  • Alashnikova said she hopes to repeat the experiment in a dustier location.
  • A global interest Australia’s unusually strong sunlight has created a national interest in exploring the factors that affect UV radiation.

Mills said, “Interest on UV radiation levels within Australia is driven primarily by health concerns.” But while Australian health officials worry that climate change might increase UV radiation and skin cancer risk, scientists note that the same factors that could lead to changes in UV may also affect the climate.

Increased aerosols may contribute to a feedback cycle that increases warming, or they might lead to a negative feedback cycle that dampens warming. Such changes could have broad implications for people and the environment. However, before scientists can incorporate those factors into climate models, they need to understand how aerosols interact with the environment.

Scientists must understand not just aerosol amount, but also aerosol type and how aerosols affect different wavelengths of light. Kalashnikova said, “We need to understand every part of the spectrum, from UV to infrared. Atmospheric studies show that aerosols have a very big effect on the climate, but that effect is not well understood.” Although it is well accepted that aerosols have an overall cooling effect on the environment, climate scientists still do not understand how changes in total aerosol amount and properties affect the climate on local and global scales.

Observing the interplay between UV radiation and aerosols may help scientists tease out the connections and better understand one aspect of the tangled interactions that link climate, dust, smoke, and UV.

Does South Australia have 2 time zones?

Anomalies – Road sign near Broken Hill Yancowinna County in New South Wales Unlike the rest of New South Wales, Broken Hill and the surrounding region (specified as Yancowinna County ) observes Australian Central Standard Time (UTC+09:30), a time zone it shares with nearby South Australia and the Northern Territory.

  • Heron Island, 72 km (45 mi) off the coast off Gladstone in Queensland, has two time zones: the island resort follows DST all year round, whereas “the Marine Research Centre and the Parks and Wildlife office on the island remain on Eastern Standard Time.
  • Resort manager Alistair Cooray says no-one is sure how the time zone came about.

‘I believe it started in the late ’50s early ’60s as a way to give the guests a bit more daylight time on the island and no-one knows for sure though. ‘ ” Lord Howe Island, part of the state of New South Wales but 600 kilometres (370 miles) east of the Australian mainland in the Pacific Ocean, uses UTC+10:30 during the winter months (30 minutes ahead of the eastern states), but advances to UTC+11:00 in summer (the same time as the rest of New South Wales).

  • A compromise between Western and Central time (UTC+08:45, without DST), unofficially known as Central Western Standard Time, is used in one area in the southeastern corner of Western Australia and one roadhouse in South Australia.
  • Towns east of Caiguna on the Eyre Highway (including Eucla, Cocklebiddy, Madura, Mundrabilla and Border Village, just over the border into South Australia), follow “CWT” instead of Western Australian time.

The total population of that area is estimated at 200 people. This area did not change when South Australia introduced DST. During the Western Australian trial of DST from 2006 to 2009, this area also sets its clocks ahead one hour during summer. This time zone is not officially recognised, but is marked by official road signs.

Why is Australia so hot if its so far south?

Australia gets more sunlight during the summer primarily because it is closer to the equator than the landmass of other English-speaking countries like the U.S. and the U.K. Also, the Earth is closer to the Sun in January (summer in the southern hemisphere) than it is in July (summer in the northern hemisphere).

Why cities in Australia have different time zones?

Because Australia is a large country. East to West with a three hour difference between sunrises or sunsets (hence three time zones East, Central and West). But it is also a large country north to south meaning a large difference in the sent length if the day between the south and the north.

Why does the sun set earlier in Brisbane than Melbourne?

One of the consequences of living in Australia is there is less daylight on summer evenings compared to the United Kingdom. The reason for this is largely due to latitude. Most southern Australian cities are around 31-35 degrees south of the equator, compared to London at 52 degrees north (and Scotland close to 60 degrees north).

The result of this is that although the amount of daylight is the same over the year, days in winter are longer, and summer days shorter, than is the case in countries like Britain or Canada. In London or Vancouver, summer days are around 16 hours long, while winter days last only 8 hours. In Sydney and Perth, summer days are only around 14 hours long, although winter days last for 10 hours.

In tropical Australia, the length of the day is close to 12 hours all year around. Geoscience Australia publishes a site allowing calculation of sunrise and sunset times in Australia. Sunset times in Summer On 21 December, the sun rises and sets at the following approximate times in the major Australian cities:

Adelaide 0558 / 2028 (daylight saving) Brisbane 0450 / 1842 Cairns 0541 / 1849 Canberra 0545 / 2017 (daylight saving) Darwin 0619 / 1910 Hobart 0529 / 2050 (daylight saving) Melbourne 0555 / 2042 (daylight saving) Perth 0607 / 2022 (daylight saving) Sydney 0541 / 2005 (daylight saving)

By comparison with the southern cities, Brisbane has an exceptionally short summer evening. There are a few reasons for this:

Brisbane is closer to the equator the city is further to the east than others in eastern Australia, so the sun rises (and sets) earlier. the Queensland government refuses to adopt daylight saving time.

Daylight Savings Time (DST)

Time zones are a state/territory matter in Australia. The effect of DST is to facilitate everyone starting and finishing their day earlier relative to the sun, DST is relatively uncontroversial in south-eastern Australia, although this could always change. Most of Queensland is tropical and hence does not want DST. It would be possible for Queensland to create a separate time-zone for Brisbane, but the government refuses to do this. Many Queenslanders, even in Brisbane, prefer to have daylight before the working day, rather than afterwards. Western Australia is operating DST on a temporary basis, but may stop doing do after a referendum in 2009.

Moving to Brisbane, ?

If you decide to move to Brisbane, you do need to accept the short Queensland evenings. If you end up working 9-5 you will not have much daylight after you arrive home. Some people can make arrangements with their employer to start and finish sooner in summer (especially if employer serves NSW customers). However, many Queensland employers are not flexible on a 9-5 working day. Even if you can make arrangements with your employer, your children’s school or other services may not be able to accommodate. The concept of working “summer hours” – ie, starting and finishing sooner in summer, although popular in Canada and the United States, is not common in Australia (and especially not in Queensland). If this is going to be a huge problem for you, perhaps Melbourne or Adelaide might be more appropriate for your lifestyle?

Why is Brisbane one hour behind Sydney?

The only difference between Brisbane and Sydney is daylight saving. The benefits of daylight saving become less the further you are from the equator.

Do Melbourne and Sydney have the same time zone?

Time zones in Australia – All of Victoria operates on Australian Eastern Standard Time (AEST) which is 10 hours ahead of Coordinated Universal Time (UTC). New South Wales, Queensland, Australian Capital Territory and Tasmania all share the same time zone as Victoria.
