Isca paper pulished together with Conversation articleMarch 2018

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.

Sudden Warming Paper published onlineFebruary 2018

Our new paper about the relative roles of Rossby waves and nonconservative processes has been published online in JAS. You can read it here.

MiMA talk at UMAP/Pan-GASS conferenceFebruary 2018

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.

3D Visualisation Talk at ARC Centre of Excellence WorkshopOctober 2017

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 2017

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.
