Informal info about me.
We just published this exciting piece of work about the climate change impact of the Montreal Protocol. That Protocol is the only treaty ever to be ratified by all nations on Earth, and was designed to combat the ozone hole (which it does).
Interestingly, it turns out that by coincidence it is also the most effective treaty on greenhouse gas emissions in history. There is a beautiful video done by the Australian Academy of Science about the paper and a short video teaser made by myself. The paper is available for free online here.
I am excited to be an invited speaker at the Dynamics and Variability Model Intercomparison Project (DynVarMIP) workshop on Atmospheric circulation in a changing climate in Madrid, Spain. The workshop will focus on atmospheric dynamics in climate prediction and I will be talking about stratosphere-troposphere coupling and its role in surface weather predictability.
We have an exciting opportunity for a fully funded PhD scholarship with Prof. Steven Sherwood, Prof. Tim Duty and myself at the interface between climate, physics and maths. Deadline 21 July 2019. For more details, click the banner!
After a four-year absence I am very excited to come back to the Conference on Atmospheric and Oceanic Fluid Dynamics of the American Meteorological Society. It will be great to catch up with that community and hopefully have some of those great interactions this conference is so famous for.
After months of preparation, my class on
We're finally going to the place we are all so obsessed with - Darwin, NT. Why are we obsessed with this place? We're using the radar data all the time, and running high-resolution models to study convection in and around Darwin.
Me in particular, as I will be giving a talk about the performance of the UK Unified Model and the Weather Research and Forecasting (WRF) model. Of course, performance as in "compared to the Darwin radar". So it's about time we're visiting. Will be hot and humid though...
Excited to go to the SPARC GA - if it's only half as good as the last in New Zealand, it'll be epic. My poster will be about the work with Thomas Reichler on Sudden Stratospheric Warmings. It can be previewed here.
The official close down of the ARC Centre of Excellence for Climate System Science is happening in Canberra. I was be there to let people "fly" into my model simulations in virtual reality. Photos of the event here.
The ARC Centre of Excellence for Climate System Science is coming to an end but we are doing down under full throttle with the last Convection Group Workshop at the University of Melbourne, were I will be one of the few researchers outside the Bureau of Meteorology to present results from the Unified Model explicit convection model.
Just arrived, and already teaching a full module of the UNSW Fundamentals of Atmospheric Science class. Gettin' right in there!
After a few turbulent weeks I have arrived at the University of New South Wales in Sydney, Australia. I am very excited to commence my new position as a lecturer in climate dynamics at the Climate Change Research Centre.
The idealised climate model framework Isca is now fully launched with the final publication of our paper, freely available here. I have also written a short, more philosophical article about the benefits of open source, version control, and idealised climate models in The Conversation here. Feel free to share and even comment if you like.
Our new paper about the relative roles of Rossby waves and nonconservative processes has been published online in JAS. You can read it here.
I will finally be able to present my own climate model MiMA at a conference in person. So far, Ed Gerber has done an amazing job at representing our work and MiMA, and other MiMA users presented as well, but I couldn't make it to the relevant conferences yet. This is going to change at the end of the month, were I will be giving a talk at the Understanding and Modelling Atmospheric Processes (UMAP) meeting, which is also known as the second Pan-GASS meeting.
I am excited to have been invited to give a presentation about the uses of 3D visualisation in research. I'll give the talk to the plenary during the annual workshop of the ARC Centre of Excellence for Climate System Science in Canberra, October 29 - November 1.
My newest scientific visualisation video uses YouTube's 360 degree capabilities, and brings the viewer around, above, and even into three of the September 2015 Hurricanes. It's very high resolution, so be sure to be on WiFi, and don't forget to move around with your mouse or phone/tablet! See it here. Tip: if it's too fast, you can hit "pause" and then have a 360-degree look around.
After the devastating September Hurricanes in the Caribbean (see post below), I have accelerated a project I had in mind for some time now: Adding Ocean basin domains to my live weather regions. These domains are the Tropical Atlantic and the North Western Tropical Pacific. As Northern Hemisphere Hurricane season slowly comes to an end, I will probably switch to their Southern Hemisphere counterparts in the near future.
I have now uploaded my first virtual reality rendering of my scientific model output. It works in the browser by navigating with the mouse, or with Google Cardboard on any mobile phone. Have a look here. A small tip: If you are using an iPhone, go to the sharing icon, hit "Add to Home Screen", and then open it as a normal App - that way, the annoying address bar will disappear.
My talk is entitled "Stratosphere vs Troposphere: A Dance of Scales", and will take place on 26 July. If you happen to be around, come, see the talk, have a coffee, and be merry.
I am happy to announce that our paper Untangling the annual cycle of the tropical tropopause layer with an idealized moist model has been published online on the Journal of Climate website at DOI 10.1175/JCLI-D-17-0127.1.
The paper introduces the Model of an idealized Moist Atmosphere (MiMA), which closes the gap between idealized dry or gray radiation schemes and full-blown General Circulation Models by including full radiative transfer, but neglecting clouds, chemistry, and ocean circulation. It also explores the annual cycle of temperature in the upper tropical troposphere/lower stratosphere, and shows how midlatitude baroclinicity plays an important role in setting up the observed structure.
As part of our efforts to improve the performance of convection permitting simulations with the UK MetOffice's Unified Model, I will be taking part at the 2nd Convective Scale Modelling Workshop 12-14 June. I will also visit Geoff Vallis' climate dynamics research group at Exeter University, and discuss some projects related to global climate dynamics. I will also try and pick up a brand new copy of the 2nd edition of "Atmospheric and Oceanic Fluid Dynamics", which contains a few of my scientific visualisations.
