“Anticipating the atmosphere: a look at the modern weather forecast process”

Benjamin Owen

Meteorologist, South Australian Regional Forecasting Centre
Australian Bureau of Meteorology

Our complex relationship with the world around is no more apparent than that we share with the weather. On a personal level, weather has the potential to make or break our day, whether it be warm and sunny or cold, wet and windy. From a commercial perspective, weather plays a critical role to a range of important industries which include aviation, agriculture and energy. And probably on the most profound level, weather has the potential to deliver catastrophic destruction in a relatively short time frame. It is therefore unsurprising that we depend on weather forecasts to best prepare and respond to the future weather as appropriate.

Over the past 50 years, our ability to accurately predict the weather has improved dramatically. While our understanding of the atmosphere has certainly evolved over this time, the most significant advances have come through improvements in the tools a forecaster has at their disposal. Where the challenge of 50 years ago was trying to make a forecast from the sparse information available, the challenge today is trying to create the best possible forecast from the vast amount of information available. In this talk, we take a look at exactly how forecasters go about creating a weather forecast, considering the tools used to capture the current and future state of the atmosphere, and how these are used to translate this into the forecast that is sent out to the world.

Please enter via the eastern door of the Physics building, from the roadway between the Scott Theatre and the Hub Building. There will be a person at the door to let people into the building until 6:30 p.m.  Refreshments will be available in Room G10 on the ground floor from 6:00 p.m.

ABSTRACT

There’s more to the universe than stars, planets, asteroids, comets, and space dust and the familiar matter that we interact with on a daily basis. Despite the fantastic successes of our theories that have predicted the Higgs boson and gravitational waves, there’s a lot about the universe that we can’t yet explain.

We believe that dark matter, which we have so far only detected through its gravity-based effects in space, makes up about a quarter (26.8 percent) of the total mass and energy of the universe. Something that is driving the universe’s accelerating expansion – which we call dark energy – accounts for another 68.3 percent. The ordinary matter, like stars and planets and galaxies, makes up just 4.9 percent of the total mass and energy of the universe.

It seems likely that dark matter is made up of undiscovered particles and one of the major challenges today is how to combine this possibility with our already highly successful Standard Model of particle physics that so well explains the behaviour of normal matter.

Abstract

The recent best-seller novel and the blockbuster movie “The Martian” presented an adventure tale of an astronaut marooned by his crew and forced to become the first colonist required to “live off the land” on Mars.  The story is well done and, for the most part, technically plausible but what would it take to live off the Martian land?  What can Mark Watney expect if he really did exist and had to grow his own to survive? Can we make this work in reality?  Can we test that environment here on Earth?  If so, can we make “living off the land” work to reduce the mass (and cost) of exploring the Red Planet?

Mars is a unique environment and the more we explore with our robotic colleagues, the more interesting and challenging the terrains become.  The soils are enriched in sulfates and phosphides which can be good fertilizers in some forms but toxic in others.  The surface is very dry; so dry there is nowhere on Earth as dry as Mars. Mars also has essentially no geomagnetic field protecting the surface from solar and galactic radiation, therefore some form of protected facility will be required for the crew and any other living organisms required to support the mission. It has a very low pressure atmosphere composed almost completely of carbon dioxide, and about half the incident solar energy seen at Earth.

Instead of OJT on Mars, as Watney had to do, we will need to consider these requirements in designing future Mars mission parameters and objectives. We can build some analog experiences here on Earth, though none can fully expose the future exploration teams to the true Martian environment.  One of the few places that can get close will be on the Moon.  For this, and other reasons, an extension of the lunar research program begun in the Apollo heroic phase of exploration needs to be an international space priority.

MA Hons (Edinburgh)

Abstract: The Solar System is a big place. Our galaxy, the Milky Way, is even bigger! But how big? This lecture will explore the size of moons, planets and stars, from ‘tiny’ Vesta to the largest stars like Betelgeuse and VY Canis Majoris. Real-time 3D graphics will be used to help visualise the immense scale of the stars and planets and the mind-blowing distances that separate them. Caution: You may feel small after attending this lecture, and that’s okay.

Bio: Graeme Stanley, MA Hons (Edinburgh). Graeme graduated from Edinburgh University in 1998 with a degree in Artificial Intelligence and Linguistics. In 2005, Graeme moved to Murthly, a rural village in Perthshire. Living more than a kilometre from street lights gave him greater access to dark skies which reignited his interest in back yard astronomy and astrophotography. In 2012, Graeme moved to Adelaide with his wife and young son. He fell in love with the southern sky and joined ASSA within months of arriving. Graeme presented the ASSA public lecture in April 2014 on beginners’ astrophotography. Graeme is a software developer, specialising in mobile apps for Android.

Giant Icebergs and the Future of the Antarctic Ice Sheet

Wednesday 20 September 2017, 8.00-9.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Dr Sue Cook
Antarctic Climate and Ecosystems Cooperative Research Centre

Events such as the 1 trillion-tonne iceberg which recently broke away from the Larsen C Ice Shelf capture headlines around the world. But what can these icebergs really tell us about the future of the Antarctic Ice Sheet? This lecture examines what we know about how icebergs form, how they are affected by climate change, and the implications for Antarctica’s future contributions to sea level rise.

Measuring Radiation Doses in 3-D with Polymer Gel Dosimeters

Tuesday 22 August 2017, 8.00-9.00 pm
Physics lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Professor Clive Baldock
University of Tasmania

Polymer gel dosimeters are fabricated from radiation sensitive chemicals which, upon irradiation, polymerize as a function of the absorbed radiation dose. These gel dosimeters, with the capacity to uniquely record clinical radiotherapy (radiation therapy) radiation dose distributions in three-dimensions (3D), have specific advantages when compared to one-dimensional dosimeters, such as ion chambers, and two-dimensional dosimeters, such as film. These advantages are particularly significant in dosimetry situations where steep dose gradients exist such as in intensity modulated radiation therapy (IMRT) and stereotactic radiosurgery. Polymer gel dosimeters also have specific advantages for brachytherapy dosimetry. Potential dosimetry applications include those for low-energy x-rays, high linear energy transfer (LET) and proton therapy, radionuclide and boron capture neutron therapy dosimetries. These 3D dosimeters are radiologically soft-tissue equivalent with properties that may be modified depending on the application. The 3D radiation dose distribution in polymer gel dosimeters may be imaged using magnetic resonance imaging (MRI), optical-computerized tomography (optical-CT), x-ray CT or ultrasound. The fundamental science underpinning polymer gel dosimetry will be reviewed along with the various evaluation techniques. Clinical dosimetry applications of polymer gel dosimetry will be presented.

Meet the John Mainstone Youth Lecture Tour Speakers

The 2017 AIP Lecture Series will be delivered by Dr Helen Maynard-Casely.

 

Helen Maynard-Casely is a Planetary Scientist based at the Australian Nuclear Science and Technology Organisation (ANSTO) where she uses the neutrons and synchrotron x-rays to investigate the materials that make up our solar system.  She has a PhD in high-pressure physics from the University of Edinburgh and has been lucky enough to have collected data in facilities all over the world, blowing up a few diamonds along the way.  Always keen to tell anyone who’ll listen about planetary science, she writes a column ‘The Tides of Venus’ for The Conversation and tweets @Helen_E_MC.

Helen’s talk “Journeying to the centres of the planets” takes us on a journey, not just to visit the planets of our solar system, but to get to know them more intimately though understanding their varied and downright dangerous insides.  We’ve yet to actually dive under the clouds of the gas giants, crack through the ice of the dwarf planets or drill into the rocks of the terrestrial planets – so how do we know what lies beneath planetary surfaces?

An additional regional lecture will be delivered in Mount Isa in 2017 by Dr Sean Powell. Sean Powell’s research experience is in theoretical and computational modelling of particle dynamics and diffusion and MRI characterisation of diffusion in complex pore spaces. In addition, Sean has industry experience in computer software and hardware engineering, 3D visualisation systems, and solar thermal energy research. Presently, he leads the biofabrication research team within the Biofabrication and Tissue Morphology research group at the Queensland University of Technology. His quantitative and problem solving skills as a physicist complement those of the multi-disciplinary team of biologists, organic chemists, clinicians and medical engineers. He is also passionate about learning and teaching and lectures undergraduate physics at all year levels from introductory to advanced.

John Mainstone Youth Lecture Tour 2017

This year’s AIP youth lecture tour will promote physics to senior high school students and science teachers in a selection of regional centres throughout Queensland.

Commencing in August, Dr Helen Maynard-Casely and Dr Sean Powell will present their lectures in major centres across Queensland.
