a #ClimateModel is where we discretize all the various, numerous components of the earth into FORTRAN modules.
There is
LandSurface
Ocean
PlanetaryBoundaryLayer
Aerosols
LandIce
Sea Ice ... … ...

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...

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...

Want to use a dynamic global vegetation model, but you're not a modeler? Don't own a supercomputer? We've got you covered! Eva Lieungh and Lasse Keetz developed The Land Sites Platform which runs on your own laptop and can be used through a simple browser interface: https://onlinelibrary.wiley.com/doi/10.1111/gcb.16808

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.

"Reconstructed climates are almost uniformly in the temperate seasonal forest biome, but heterogeneity of specific forest types is evident..Our results show that during the Miocene, climate was most different from modern in the northeastern states, and may suggest a drastic reduction in the meridional temperature gradient along the North American east coast compared to today."

New Energy Exascale Earth System Model (E3SM) paper showing improvements in stratocumulus simulation with both vertical and horizontal mesh refinement. #climatescience #climatemodel

How does a #climatemodel work? A longread Q&A from January 2018 explains everything, illustrated with snippets of equations and code, and a 90second clip of the hardware installation for the supercomputer at the UK #MetOffice 😁 https://yewtu.be/watch?v=q4uKS_wcfow

I used to let my Windows laptop
participate in the #BOINC project "Fight #ClimateChange At Home" or similar. The BOINC software pulled tasks from a climate model run, solved them, uploaded the results and got new tasks

Almost the last trip of the year: To Liege to talk #PROTECT +#POLARRES with the #MAR group and to examine a PhD thesis. Looking forward to some good discussions with Xavier Fettweis and the rest of the group on coupled #ClimateModel development with #ocean #SeaIce + #IceSheet, next gen #RegionalClimateModels and how to choose #CMIP6 #ESMs for #downscaling.

When did people start using the term "IPCC class" climate model?

#climatemodel #climatemodelling

Here's an animation I made for #COP last year but still very relevant (and a test of how here copes with animations).

We talk about "2 degree C" of #ClimateChange but it's not that simple... There are huge regional differences, with the #Arctic warming dramatically more than the average. Our paper looking at this in more detail in the UK's #ClimateModel is here: https://doi.org/10.1175/JCLI-D-21-0234.1

I ran this #Climatemodel at 5km resolution so the topographically driven winds really pop out like in the Nares Straits and in SE #Greenland where strong #KatabaticWinds blast off the steep margin of the #IceSheet. I'm claiming it under lines on the basis of the strong isolines demarking wind speed..

Day 2 of #30DayMapChallenge is "lines". Here is a figure from a paper I hope to submit this year showing annual mean wind speeds over #Greenland from the #HIRHAM5 #ClimateModel
