AOML and HRD researchers at 33rd AMS Conference on Hurricanes and Tropical Meteorology, Ponte Vedra, FL – 15-20 April 2018

Thirty-one AOML and HRD scientists participated in the recent 33rd AMS Conference on Hurricanes and Tropical Meteorology in Ponte Vedra, FL, as authors or co-authors on 65 presentations and 19 posters. Roughly 783 presentations (507 oral presentations in 67 sessions and 276 posters in 2 session) were submitted to the conference.

Of the 567 TC-related presentations and posters at the conference, 198, or about 35%, used data sets developed at HRD. There were 3 regular sessions and 1 poster session dedicated to HFIP with 37 presentations, plus another 72 presentations sprinkled throughout the rest of the program that reported on HFIP and IFEX related work. It was also clear that HFIP research influenced a number of other presentations through recognition of the importance of evaluating numerical model system developments.

Recordings of the 65 presentations and the abstracts for the 19 posters AOML and HRD researchers presented (or were co-authors) at the Conference are available online from the AMS website.
