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. https://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.

🆕 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.

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.)
