New work on #AtmosphericRiver families led by Meredith Fish (w/co-authors inc. @Climate_Done, Dr. Daniel Swain, @AnnaWilsonWx,& Peter Gibson). We find that nearly all interannual variability in California AR frequency is driven by successive (vs single) events! journals.ametsoc.org/view/journals/…

#climatetwitter Does anyone have a reference estimating how much CMIP6 costs, in terms of model development and runtime etc. I've heard estimates > $1B but can't track down a source

There are a lot of things to be worried about with climate change - this by far trumps them all for me

New Zealand’s August 2022 atmospheric river (AR) was the strongest August AR in the New Zealand region on record, shown by an analysis from Tristan Meyers, Peter Gibson & I. Extreme rainfall in Nelson was a 1-in-120-year event - sorry to those affected! niwa.co.nz/news/exception…

Funded by MBIE’s Endeavour fund, NIWA researchers are developing a physics-informed and AI-driven method to vastly reduce the computer power needed to provide accurate climate change projections. 🖥️ Find out more here 👉 niwa.co.nz/climate/resear…

🚨NEW JOURNAL PAPER ALERT!🚨 Promising results for NIWA researchers who have been using deep learning to produce high-resolution climate projections and weather forecasts over NZ’s complex terrain. Read here 👇sciencedirect.com/science/articl…

I'm told ChatGPT has been upgraded to be able to solve math problems and that is it the future of math tutoring. But my hit rate is ~0 so far... and I wasn't even trying trick questions. Not dissing the system at all -- just a PSA.

The last 100 years of May temperature anomalies. This is what a developing El Nino at 420ppm looks like. El Nino at 500pm will be something else. Data: data.giss.nasa.gov/gistemp/

One of the benefits of my job running high-resolution climate models: data visualisation of what they can spin up. When we push to high enough resolution we begin to see emergence of cat-5 tropical cyclones like this one😳. Note this doesn't correspond to a real world event

Important paper subjecting an AI global weather model to atmospheric dynamics tests. Beautiful work by Greg Hakim at UW and Sanjit Masanam. Equation (1) was a crafty idea to tease out response to perturbation & forcing relative to smooth climatology. arxiv.org/abs/2309.10867

The last 50 years of global warming. Wait till the end to see how ridiculous and widespread September 2023 warmth was. Data NASA GISTEMP. Shown are temperature anomalies relative to 1951-1980 base period #wxtwitter #climatechange

Excited to lead this newly funded Marsden Fund proposal, with help from Neelesh Rampal, working out the how's and whys of atmospheric river changes in a warming world. Despite the devastating impacts of atmospheric rivers, there is still lots we don't know

Small Island states need high resolution climate projections in order to understand and plan for climate change @scigibson nature.com/articles/s4155…
