New paper out! A look at the climate and weather scale for the 2018 summer heat wave. Focussing on Germany and Scandinavia it has also some interesting points for Ireland. Published in @EGU_NHESS nhess.copernicus.org/articles/23/16… (1/11)

1/n Interesting to monitor the forecast for the seven #LSDPatKIT North-Atlantic European regimes in the advent of the major warming going on in the stratosphere – a thread for the weather experts.

The stratosphere is preparing for a sudden stratopsheric warming (SSW) event, meaning a breakup of the stratospheric polar vortex — what does it mean for weather at the surface? 1/n washingtonpost.com/weather/2023/0…

1/ There has been a recent hype about the polar vortex, so I want to add some info (and an SSW poll — better late than never, see further down in thread). By “polar vortex”, I mean the stratospheric vortex at ~20-50km above the Earth’s surface over the polar regions in winter.

@MattPattClimate @aduesterhus @atmosbarnes Thanks @MattPattClimate! We are currently working on it, using a seasonal forecast system and reanalysis data.

Could we potentially use spring North Atlantic SSTAs to anticipate European summer heatwaves? Check our new paper in collaboration with @aduesterhus, @atmosbarnes, Wolfgang A. Müller and Johanna Baehr. agupubs.onlinelibrary.wiley.com/doi/full/10.10…

A great new paper in GRL by Goratz on the connection between Sea Surface Temperatures and European Summer Heatwaves on seasonal scales done with a neural network approach. (1/7)

A week full of networking and science outreach! Many thanks to @BC3Research, @NaturKlima, @ZarautzOn and @GKale_Nagusia.

Excited to present the progress of my PhD in my hometown! Thanks @ZarautzOn for the opportunity. #heatwaves #neuralnetworks

The Basque language has always been surrounded by mystery with regards to its origin. Today, there has been a massive breakthrough on its history and origin 🧵

'The extremely hot and dry 2018 summer in central and northern Europe from a multi-faceted weather and climate perspective' See our new preprint open for discussion @EGU_NHESS led by @syn_efou as a joint effort from #ClimXtreme @BMBF_Bund project members egusphere.copernicus.org/preprints/2022…

A new study suggests the increasing frequency of western European heatwaves is linked to increased persistence of Eurasian double jets in the upper troposphere. @syn_efou @Kkornhuber @BeobideG @FeiLuo_Climate @DimCoumou @PIK_Climate nature.com/articles/s4146…

Our new study on European #HeatWaves covered by New York Times @nytimes nytimes.com/2022/07/06/cli…

New study: Europe is a heatwave hotspot, exhibiting upward trends that are three-to-four times faster compared to the rest of the northern midlatitudes. The reason: changes in the jet stream. nature.com/articles/s4146…

"We've been warning against climate change for about 50 years or so." We spoke to new laureate Klaus Hasselmann just minutes after the announcement of his #NobelPrize in Physics. Take a listen:

The response of El Niño–Southern Oscillation to the #ClimateCrisis is discussed in this Review by Wenju Cai et al., including increases in ENSO magnitude, ENSO-related rainfall, and SST variability. nature.com/articles/s4301… free: rdcu.be/cv4f4

A strong manifestation of the Circumglobal Telecconnection (CGT) pattern is showing up just after mid-July, esp on the GEFS. This pattern is in large part forced by subseasonal enhancement of the Indian Summer Monsoon. See Beverley et al (2021) for more: link.springer.com/content/pdf/10…

Just out: our new paper affirming the unprecedented slowdown of the Gulf Stream System (aka Atlantic meridional overturning circulation, 𝗔𝗠𝗢𝗖) in Nature Geoscience! @NatureGeosci A thread. 1/11

The winter heat is starting to gather momentum. This is just the beginning with countless records about to fall later this week. Hamburg, Germany 🇩🇪 just shattered the record for its hottest winter day ever. Average for this time of year is closer to +4°C.
