#climatemodel

22 people in the monthly #HCLIM meeting - I remember when you could comfortably fit us all around a single home dining table - Europe's common regional #ClimateModel is taking shape nicely...

"Rapid progress in the use of machine learning for weather and climate models is evident almost everywhere, but can we distinguish between real advances and vaporware?"

Another piece of #ClimateModel and #IceSheetModel work presented by colleague Christian Rodehacke, with work from the @AWI@helmhotz.social group using a coupled system to show how the 2 ice sheets might work together and separately in the climate system as also part of @H2020protect.bsky.social

The great Scandinavian drought of 2018 cost Danish agriculture alone ~ EUR 550million - what are the prognoses for the future?

Great talk by our #NCKF PhD student Rüben Haberli on high res convection permitting #ClimateModel simulations to understand #drought in #Scandinavia

I'm not a scientist, but this is how a model collapse of AMOC actually looks like. Source link in second reply.

Right axis = Sv = flow of water
Grey line = AMOC

• 150 years = slow reduction in flow from about 12 to 10 Sv
• 100 years = yellow band = collapse of Amoc. It drops roughly from 10 to 2 Sv
• 150 years = slow reduction to zero flow

“KEY POINTS
• [They] dynamically downscaled 15 CMIP6 global climate model simulations over Australia to a 10 km spatial resolution using the Conformal Cubic Atmospheric model
• Two new assessment metrics are proposed to assess model performance and added value of downscaling
• The integrated added value of downscaling can be as high as 150% over highly populated areas..."

“KEY POINTS:
• A climate model is used to test the hypothesis that creating a large lake in central Australia would increase rainfall
• Locally, surface cooling effects of the lake suppress the formation of precipitation
• Regionally, moisture from the lake is exported to other areas but the amount is small compared to natural variability in Australian rainfall..."”

In searching for something else, I stumble across @reuterbal 's
epic thread on #Loki

- no not *that* Loki, but an ingenious sounding source translation package for
#Fortran to allow the #ECMWF #IFS model to run on GPU's.

What a cool piece of software...

Worth a deep read for #NWP + #ClimateModel nerds...

https://mast.hpc.social/@reuterbal/110476253044838075

TFL you have 9.5 million special project simulation units to last a whole year at the @ecmwf +while writing the project report *only half way through* you realise you've already spent 10.5 million of them testing a new #ClimateModel of #Antarctica...

#oops
#PolarRES #ECMWF #SpecialProjectECMWF

Interesting how close @awi * #ClimateModel #AWICM is to the #ECEARTH #GlobalClimateModel now

It will never not be funny that the vegetation model in the #UKESM glob #ClimateModel is called triffid.
Robin Smith taking is through the details.
