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 https://t.co/YoHcwg9f1I (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

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.

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)
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 🧵

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

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.

"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.

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.

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.
