🌡️📈 Europe has been experiencing some of the hottest temperatures of summer 2023 so far.

But what is influencing this #heatwave, what are its potential consequences, & is #ClimateChange affecting it?

Today at #IWSM2023 @retostauffer presents our work on long-term #foehn reconstruction

Requires several steps:

1a. Foehn cannot be observed directly, classified based on temperature, humidity, wind speed.

1b. General weather characterization based on #ERA5 reanalysis.

📈According to #ERA5 the 7 days from 3rd to 9th July 2023 were the 7 hottest days on record globally, making the first week of July 2023 the hottest week on record.

May SeaIce highlights from #C3S:

#Antarctic sea ice extent reached a record low monthly value at 17% below average;

#Arctic sea ice extent was very close to average and almost identical to the value recorded in May 2022.

@Ruth_Mottram would be interesting to see what it looks like relative to #ERA5 or if it even makes a difference

The Historical Weather API now dates back to 1940 with the latest #era5 upgrade!

https://openmeteo.substack.com/p/historical-weather-data-from-1940?utm_source=mastodon&sd=pf

In February 2023, most of western #Europe experienced below-average soil moisture, reaching more than 4% below average in many regions, and more than 8% below average in parts of Spain and Türkiye. Although not as low in magnitude as for Spain and Türkiye, the soil moisture levels in parts of Ireland, UK and France, were lower than any previous February in the #ERA5 soil moisture record from 1979.

Hourly reanalysis data from ERA5, the fifth-generation global climate and weather reanalysis, is now available from 1940 to the present day!
This extends the ERA5 data record to over 83 years & is the backbone of many C3S products & services.

Figure below shows a 1941 storm over NW Spain - now resolved by ERA5

@Ruth_Mottram that is an interesting result indeed!

It seems to have come a long way from the #MetNet project.

#ERA5 #ecmwf #DMIDk #Climate #weather #machinelearning #chatgpt

Amid #ChatGPT hype there has been a remarkable advance in use of #machineLearning for #Weather + #Climate- my ace #DMIdk colleague Peter Ukkonen shared this (uses #ECMWF #ERA5 as training data!)

"Our results show GraphCast is more accurate than ECMWF’s deterministic operational forecasting system, HRES, on 90.0% of the 2760 variable + lead time combinations ... GraphCast can generate a 10-day forecast (35Gb of data) in under 60 seconds on Cloud TPU v4 hardware."

https://arxiv.org/pdf/2212.12794.pdf

Update: it worked!

I was making sure we can seamlessly transition from #ERA5 to #ECMWF operational forecasts for forcing #ORAS6

It's not often I look at real fields but you can really see the effect of the higher resolution forcing and fluxes, even on the fixed ocean grid
