Brutal field trip provided new insights into Arctic winter

Hi all, We are excited to announce an upcoming workshop, "Technological Advances in Climate Modelling", taking place June 15–19 at Bjerknes. We have invited five climate model developers to lead a mix of talks and hands-on sessions throughout the week. The current program is as follows (subject to change): • Monday morning: Introduction to Julia and script-based and interactive ESM modelling • Monday afternoon: Introduction to GPU modelling • Tuesday morning: Hands-on experiments using Oceananigans (ocean), SpeedyWeather (atmosphere), and Terrarium (land surface) • Tuesday afternoon: TBD – possibly biogeochemistry-focused • Wednesday morning: Hybrid physics–ML modelling, differentiable ESM modelling, and more • Wednesday afternoon: A bit of continuation from the morning, and afterwards we will have a couple of hours for discussions and general questions of everything introduced since Monday • Thursday morning: Coupled ocean–atmosphere simulations using script-based and interactive ESM modelling (it can be easier than you think!) • Thursday afternoon: Coupled atmosphere–ocean large eddy simulation (LES) / nonhydrostatic modelling, with examples such as prescribed sea-ice leads or complex topography • Friday: TBD; more discussion time This workshop is designed to cater to a wide range of experience levels — from those running their first ocean, atmosphere, or land surface simulation, to seasoned modellers looking to deepen their knowledge of GPU computing, hybrid physics–ML approaches, and more. The introduction and hands-on sessions on Monday and Tuesday in particular are aiming to be beginner friendly, even if you have never approached a model, or Julia/GPUs, before. You are welcome to join only the sessions most relevant to you; there is no expectation to attend the full week. Our guest experts will be around for most of the week and will be available to discuss and help you get started. We are also in discussions with Sigma2 about using their new supercomputer Olivia, which is equipped with the latest-generation GPUs and opens up exciting new possibilities for climate modelling. A sign-up sheet will be circulated after Easter, once the program is finalised. In the meantime, we encourage you to block the week in your calendar if you are interested in joining. Do not hesitate to get in touch if you have any questions — we look forward to seeing many of you there! Best regards, Kjersti Daae, Guillaume Boutin, and Andreas Klocker

Qidi Yu disputerer 15.6.2026 for ph.d.-graden ved Universitetet i Bergen med avhandlingen "Forecast biases and errors – A feature-based approach and the role of diabatic heating". Mer informasjon her: Systematisk identifisering av værvarslingsfeil | Nye doktorgrader | UiB

Instead of the workshop that was initially planned, we have opted for a smaller format with two invited talks and a discussion session: Huiji Lee: Alkalinity Redistribution Leads to Weakened Global Ocean CO₂ Uptake Pushpak Nadar: Enhanced Antarctic Intermediate Water Ventilation During Past AMOC Weakening and Implications for Thermocline Biogeochemistry Both speakers will present their work in a way that is accessible to a broad audience. After the talks, Are will lead a discussion session, followed by a joint lunch. We also hope that Ralph Keeling will be able to join us. Time: 23 June, 11:00–13:00 Lunch: Provided free of charge If you would like to attend, please fill out the registration form by 12 June (so that we know how much lunch we should order): Carbon Theme meeting, 23.06., 11-13h – Fill out form
