“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.

Special Pre-lecture tour of the State Library Exhibition

‘From Outback to Outer Space: Woomera 1955 – 1980’

5:15pm for 6:00pm, State Library of South Australia

Register for a free ticket (first 40 registrations only) using the same link as above

Woomera put Australia into the space age. The ‘From Outback to Outer Space: Woomera 1955 – 1980’ exhibition will not only tell the story of that journey into the stars, but also what life was like for the men, women and children who lived on the ground. Presented by the State Library and the National Archives of Australia.

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.

Free, visitors welcome. Booking not required (*Please note: university security locks entrance doors at 8pm sharp*)

Bronze Bragg presentation and lecture

The Australian Institute of Physics (SA branch)

Physics, Power and Climate Change

Tuesday 11th of April 2017 at 6.30 to 7.45 pm
Napier 102 lecture theatre
1st floor, Napier Building,
University of Adelaide (off Victoria Drive)

Professor David Jamieson
University of Melbourne

Although the human responses to climate change are volatile, the laws of Physics are not. Since the 1905 Chemistry Noble laureate Svante Arrhenius first modelled the greenhouse effect on the temperature of our planet little has changed from his prediction of a 2.1 degree Celsius temperature rise for a doubling of the 1905 carbon dioxide levels in the atmosphere.  Today, with greatly improved physical models, the prediction is between 2 and 4.5 degrees under the same scenario.  Physics helps us understand the past, present and future scenarios for the climate of our planet.  Working out what to do about our emissions and climate change requires us to look at our present and future energy budget.  But it is power that drives our civilisation, not energy.  The paths from energy to power are constrained by the unbreakable laws of entropy.  This lecture explains entropy and the big challenges involved in charting the uncertain future.  Please bring your smartphone to participate in the online polling during the lecture!

The Bronze Bragg medal and merit certificates will be presented at the lecture. The medal is awarded for the best performance in 2016 in Physics in the Stage 2 SACE assessments, with certificates being for students who achieved a merit.

The presentation and lecture will be held in the Napier 102 Lecture Theatre, Napier Building, 1st floor, University of Adelaide, North Terrace, north from Pulteney St., at 6.30pm. Members of the public are warmly invited to attend. We are obliged for security reasons to keep the front door of the building attended, so please arrive before 6.30pm. Bookings are not available.
