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 … Continue reading Paper on the unusual eyewall replacement cycles in Hurricane Irma published in Monthly Weather Review

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 … Continue reading AOML Flies Science Missions into Succession of Atlantic Storms

HRD observation team monthly meeting – 21 November 2019

The purpose of the observation team meetings is to bring together the people who use observations in their research on a regular basis to discuss issues they’re having, provide updates on observations they’re analyzing or collecting, and any other information that may be of interest to the broader group.  These meetings are also an excellent … Continue reading HRD observation team monthly meeting – 21 November 2019
