Climate modelling and weather forecasts – low 2 by 2 degrees grid resolution versus higher resolution.

Daniel Swain's Office Hour about the Texas #FlashFlood included much explanations how weather models work nowadays. youtube.com/live/OJEddh6dhrU
In this excerpt, (at 1hr:9min) he shows the accumulated amount of rain as predicted by various weather models, high resolution ones, and what can be called global weather forecast models in much lower grid resolution.

He emphasizes that AI models did the worst in predicting the exceptional event on July 4.

Now, this weather event involved convective activity which is apparently something that global models don't have detailed-enough formulae for. As Daniel says, it's expected that their rain amounts won't depict what's happening on the ground.

But their low resolution is also "to blame".
in June, Brunner et al published a comparison between normal CMIP6 2x2° climate models and how many future temperature extremes (#heatwave and maximum °C) can be teased out from them – which is important information for us, for city planners and insurance companies and the like – 
versus how many extremes two very fine-grained climate models find in their 9 to 15km grid. Spoiler: plenty more.

The US based Weather and Climate Livestream will be livestreaming for 100 hours, starting on Wednesday May 28 at 1pm ET.
Here is their intro video:

Why is this important? The Trump administration is cutting funding for weather research and forecasting, so lots of scientists have joined together for this live-stream.

Please #boost.

East Africa: Horn of Africa to Be Wetter Than Usual From May to July, Says ICPAC: [ENA] Addis Ababa, -- Most parts of the Horn of Africa are expected to be wetter than usual between May and July 2025, the Climate Prediction and Applications Center (ICPAC) of the Intergovernmental Authority on Development (IGAD), an East African bloc, said Tuesday in its latest forecast. newsfeed.facilit8.network/TKSS #EastAfrica #HornOfAfrica #ClimateChange #WeatherForecast #ICPAC

The natural climate pattern La Niña started to make her presence felt last fall. Now, she's on her way out. According to a new National Oceanic and Atmospheric Administration report, things have shifted into a "neutral" phase, which is forecast to last into at least early fall. Forecasters are predicting an active hurricane season and above average temperatures nearly everywhere in the U.S. aside from the Pacific Northwest and parts of the Northern Tier. Here's more from @CNN.
