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

Lead Impacts on the Moist Static Energy Budget of the Low‐Level Arctic Atmosphere in Large‐Eddy Simulations Based on MOSAiC Data
Idealized leads are introduced into a set of large-eddy simulations based on Multidisciplinary drifting Observatory for the Study of Arctic Climate field campaign data during polar night Lead imp...

Meteorologist Matthew Cappucci flew into the eye of Hurricane Melissa, a Category 5 storm that is projected to hit Jamaica. “It was equal parts scientifically stunning and horrifying from a humanitarian standpoint,” he wrote, flying in one of two groups of hurricane hunters. wapo.st/42XpWmq

Simply incredible imagery of Hurricane Melissa this morning as it approaches Jamaica.

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...

🆕 The discovery of new complex organic molecules at Saturn's #Enceladus enhances the likelihood that the moon is habitable 🪐 On Earth, these molecules are involved in chemical reaction chains that lead to the more complex molecules essential for life. Read more 👉 www.esa.int/Science_Expl... 🔭 🧪 ☄️
Scientific illustration showing a cross-section of Saturn’s moon Enceladus. It features three labelled layers: An ice shell at the top, with visible cracks releasing jets of water vapour into space; an ocean in the middle, depicted as a large body of water beneath the ice; a rocky core at the bottom, shown emitting heat that may drive the jets. In the background, Saturn and its rings are visible in space.

So this is pretty amazing - yesterday EarthCARE sampled Hurricane Humberto straight across the eye! The eye of a tropical cyclone is small so a direct hit is rare: this is the first time EarthCARE has hit one after over a year in orbit! (Showing here also VIIRS on NOAA-20 for context.)

We recently published a paper on how the low entrainment efficiency of Arctic mixed-phase cloud layers is influenced by wind shear and radiative effects using dozens of high-resolution Large-Eddy simulations @ametsoc.org doi.org/10.1175/JAS-...

I will present our current work on simulating the impact of leads on the Arctic atmospheric boundary layer at #AGU24 @agu.org / Contribution C41E-0231. This is strongly based on our recently published paper in JAMES: doi.org/10.1029/2024...
