End of a great week at the storm tracks conference in Oléron. Lots of interesting science and good discussions. Looking forward to the next one! #oleron #stormtracks

The elegant weather maps by Tomer Burg point out that the mid-June European heatwave is "partnered" with two other anomalously hot areas: one SE of Greenland, the other over Middle East ♨️ These hot spells are joined by a single, NW-SE oriented Rossby wave packet in the jet stream〰️

Whoop!🙌 Fluids Symposium 22 University of Leeds Leeds was a great success! Fantastic speakers, great attendance and really well organised by the postgraduate team @rm_collet Michael Jacob Perez 👏

Just published: Schwartz, Garfinkel et al, incl Priyanka Yadav: Model biases in extratropical stationary wave patterns lead to significant forecast errors. Improving on these biases will likely improve the long-range prediction of extreme events.

The 1976 heatwave was very different in character to the short, sharp event of this week, and there are a few other interesting comparisons: 1/4

Since folk have asked, here's how the jet has been in July - bent north over W. Europe, setting the scene for the heatwave to develop to its south. In the UK the jet has protected us from most of it, but it just let a little of the hot air slip north. (anyone notice? 😉)

The 2nd part of our @AMSJCLi study on drivers of biases in CMIP6 storm tracks was recently accepted and now available online! In this part we looked into the Southern Hemisphere and tried to understand the influence of SSTs and temperature gradients ⤵️ doi.org/10.1175/JCLI-D…

WALL OF WATER! 🌧️👀 Crazy time-lapse today showing severe weather with heavy rain and strong wind blowing into Fort Myers, Florida. Looks like the Mothership! @WINKNews #StormHour Stephanie Abrams Jim Cantore

Jacob Perez presenting his interesting work developing a new approach for diagnosing the North Atlantic eddy driven jet at #iugg2023 EPSRC CDT Future Fluid Dynamics @ICASLeeds

Thanks to everyone that came to my talk yesterday. Look out for the paper in the near future! #iugg2023

The Jet stream is a band of winds coming the west, that has large impacts on our surface weather. My research involves developing new methods to characterise the jet position, strength and tilt and how these features alter the location of extreme weather (1/3). #CDTTweCon

In my work we have developed a new way to characterise the Jet, by extracting what we call Jet objects from the wind data. The Jet position (blue dot), tilt and strength are all calculated by using the winds within Jet object. (2/3) #CDTTweCon

By considering different Jet characteristics, leads to different surface impacts! Below is a plot of the rainfall (blue-wetter, brown -drier) where the tilt is increasing from left to right. Changes in the tilt lead to different wet and dry areas in Europe. (3/3) #CDTTweCon

Discussion open for comments on EGUsphere: A new characterization of the North Atlantic eddy-driven jet using 2-dimensional moment analysis doi.org/10.5194/egusph…

Weak eddy feedback has been proposed to explain the NAO signal-to-noise problem. Our new study highlights limitations of the diagnostic used in some earlier studies and question the interpretation in past work Dr Christine McKenna (she/her) CONSTRAIN @ICASLeeds agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

Discussion open for comments on EGUsphere: Minimal influence of future Arctic sea ice loss on North Atlantic jet stream morphology doi.org/10.5194/egusph…

Our new paper led by Jacob Perez suggests a method to diagnose the North Atlantic jet using moment analysis: wcd.copernicus.org/articles/5/106… Really pleased to see this work finally come out. We hope it will be used by others. Well done Jacob! @ICASLeeds
