Interesting!

Somebody should also check what is going on in ERA5 north of Greenland.

October 2021 was globally the 3rd warmest (as per ERA5 data).

But if considering only the land area (where we people actually live!), the month was the *1st warmest* on record.

The peak intensity of today's storm (~962 hPa) is close, if not even outside the ERA5 1961-2020 climatology for October.

Very unusual storm for the time of the year!

Les 1eres estimations tombent. Alors que les français se plaignent de la pluie pour leur vacances (pour les récoltes, c'est autre chose), ils ne comprennent pas leur chance.

Le mois de juillet est le mois le + chaud jamais observé sur Hemi N (ERA5). Comme ca, c'est clair 👇

June 2020 temperature anomalies in Arctic Siberia were striking.

The maximum temperature anomaly in ERA5 0.25° gridded data was 10.3°C, which is the highest value in the Northern Hemisphere at any summer month since 1979 (so in the whole dataset).

We have just published WFDE5, a bias-adjusted ERA5 reanalysis dataset. It was developed solely within our Toolbox!

WFDE5 will contribute to ISIMIP to adjust GCMs & to evaluate & drive a wide range of impact models.

How is the year shaping up in terms of temperature against the latest 10 year climate average (2009-2018)? Using the ERA5 reanalysis from the boys , Jan-Oct has been colder in large parts of North America and notably warmer in Alaska & a large area of Russia.
