Okey, nice! Yes, something like identifying the leads, broadly categorizing them based on widths, wind speed / direction, stability and cloudiness upstream, and then check impact on the sea-ice / TOA radiation downstream, would be my first instinct.

We have a new preprint online at ESS Open Archive, under review at JAMES. We conducted LES to investigate how Arctic leads impact the moist static energy budget of the ABL and, for example, found that lead plumes are highly effective in removing heat via longwave radiation. doi.org/10.22541/ess...

Thanks a lot! I unfortunately had not seen the figure before, sorry, would have been a great reference.. So cool to see these larger leads resolved in the model with the immediate impact on the atmosphere. Do you see anything regarding clouds / radiation downstream of the features too? Cheers

New paper! 🎉 How do Arctic leads (cracks in sea ice) affect the atmosphere under different conditions? Condensing plumes can act as "radiator fins", efficiently removing energy downstream; sometimes cooling the air even more than the lead initially warmed it! @agu.org @unicologne.bsky.social

On my way to Paris, in the midst of the heatwave, not looking forward to two days in a scorching city 🥵 (currently at 40 degrees). 🔥 Heat waves like this are becoming more and more likely due to climate change. I fear the record for the warmest day broken yesterday won't stand long.
