HRD Debrief for missions into Hurricane Dorian – 30 January 2020
HRD researchers discussed the results from the 15 P-3 and 10 G-IV missions into Hurricane Dorian, AL05 (26 August – 5 September 2019). The format of the debrief was different than in the past. A brief overview is provided of the storm and missions, followed by a series of 8 short presentations discussing planned and […]
Paper on daily changes in hurricanes published 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 […]
HRD at the American Meteorological Society Centennial Meeting
HRD scientists recently attended the 100th American Meteorological Society Meeting in Boston. There, they presented 33 oral presentations and 10 posters. You can access the abstracts and recorded talks (when available) by clicking on them.
Paper on differences in rainfall between tropical disturbances that form into tropical cyclones and those that don’t published in Monthly Weather Review
Summary: Many weather satellites are outfitted with instruments that can see through clouds to sense where and how hard it is raining (the rain rate), and how much of the rain is occurring in deep convective clouds (cumulus and cumulonimbus clouds that form when warm air rises). They can also see tropical disturbances, which are usually […]
Paper on the unusual eyewall replacement cycles in Hurricane Irma published in Monthly Weather Review
Summary: Accurate forecasts of hurricane strength are necessary to protect people in the path of a storm. The strongest winds in a hurricane are found near the center of the storm, in a ring of dangerous weather called the eyewall. As a hurricane grows older, it is common for the eyewall to eventually weaken and get […]

Paper on the intensification of tropical cyclones in wind shear published in Mausam
Hurricanes are fed by energy from the warm ocean. The center of a hurricane is surrounded by tall clouds, called cumulus clouds, that produce the heat needed to keep the spin, what we call vorticity, in the hurricanes going. When there are a lot of cumulus clouds around the hurricane’s center, the hurricane spins more rapidly. However, […]
