3D Visualisation Talk at ARC Centre of Excellence WorkshopOctober 2015

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.

New 360-degree video of Irma, José and KatiaOctober 2015

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.

New live 3D weather domains October 2017

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.

New movie of the September 2017 Hurricane activity October 2017

I have made an animation incorporating Harvey, Irma, Jose, Katia, Lee, and Maria. This runs from August 20 to September 30 2017, and can be seen in my movie section or directly on my YouTube channel.

MiMA paper published online June 2017

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.

Visiting Exeter UK June 2017

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.

Animation of Tropical Cyclone Debbie April 2017

Tropical Cyclone Debbie devastated large parts of the eastern Queensland coast and flooded much of northern New South Wales during its passage at the end of March 2017. This was the first tropical cyclone hitting the country I live in since my live weather website is up, so I have been able to follow its evolution very closely. I have created an animation of the cyclone from its formation all the way to its passage back onto the sea. You can see it in the movies section of my visualization page or directly on YouTube here.

Talk at Bureau of Meteorology March 2017

The Australian Bureau of Meteorology asked me to present my most recent results on stratosphere-troposphere coupling and possible applications to seasonal forecasting. I've spent a very interesting day at the Bureau, thanks to everyone for some exciting discussions!

Full program at AMOS conference February 2017

I'm excited to present both a poster and a talk at this year's Australian Meteorological and Oceanographic Society (AMOS) Conference. The poster will be about my newest research on tropical convection over the Maritime Continent, whereas the talk will be focused on the Model of an idealized Moist Atmosphere (MiMA). The latter will combine both tropical convection, tropospheric turbulence, and stratospheric dynamics, so it's going to cover a lot of material.

Busy AGU Fall Meeting December 2016

My visit of San Francisco is a busy one. Starting off with the invited talk delivered by Ed Gerber about my Model of an idealized Moist Atmosphere on Monday morning, I will present my newest publication as a poster on Tuesday, and will go on to present my colleague Claire Vincent's work on the Madden-Julian Oscillation on Wednesday. Looking forward to some serious science discussions (and also a few nice views of the Bay of course).

SSW paper published December 2016

My most recent paper about Sudden Stratospheric Warmings has just been published. It uses an idealized GCM to see whether or not SSWs are (once they happen) similar to each other (yes), if there are differences between those that influence the surface weather and those that don't (yes), and if we can identify an entirely different "species" of SSWs which propagate (no).

ARCCSS newsletter article October 2016

I've written a small piece about the Dos and Don'ts in scientific visualisation, with the example of my newest addition to my website, Weather Alive. If you'd like to know more about how such things can be done, go have a read.

Introducing my new weather page September 2016

After months of working on it every now and then, I am proud to reveal my very own weather page. You'll be able to look at the cloudiness and winds over the entire globe, or look into more detail in one of several regions. There's also a time picker, where you can travel into the past (sorry, no earlier than 1. August 2016), or the future! If your browser supports it, you can even look at it in 3D and use your mouse to navigate everything. Last but not least, have a look at some of history's most impressive weather events - in 3D of course. Go enjoy the weather here!

Featured video on Paraview websiteApril 2016

One of my pv_atmos videos (Fly Me) has been chosen as one of six to showcase the power of their software on the main page. Have a look here.
