Paper on daily changes in hurricanes released online in Geophysical Research Letters

Summary: The very tall clouds that we see in satellite pictures of tropical cyclones (also known as hurricanes) fan out from the hurricane's center over the course of each day, what we call a diurnal cycle. This is because a pulse of thunderstorms and rain forms near the hurricane center each night and steadily moves …

AOML Flies Science Missions into Succession of Atlantic Storms

“Many of the storms we flew in 2019 were ‘living on the edge,’ in that they were weak, vertically sheared, but also unpredictable. In previous years, we saw these storms intensify, such as Hurricane Michael in 2018. This season, many struggled to intensify. As we continue to build a dataset of these sheared storms, we …
