AOML and HRD researchers at 30th AMS Conference on Hurricanes and Tropical Meteorology, Ponte Vedra Beach, FL – 16-20 April 2012

There were over 600 abstracts submitted to the conference of which 593 were presented (427 oral in 65 sessions and 166 posters in 3 poster sessions). Of the 593 presentations roughly 85% were related to tropical cyclones. 16 HRD scientists (of which 5 were CIMAS) and 2 PhOD scientists participated in the conference as authors or coauthors on 44 presentations (35 presentations and 9 posters). They also chaired 6 sessions. Of the 500 TC-related presentations roughly 24% (119) mentioned or used data sets developed at HRD (H*WIND appears to be a favorite product for model evaluations). There were 3 dedicated sessions to HFIP and IFEX with 24 presentations, plus another 30-35 presentations sprinkled through 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 developments and simulations over numerous cases.

Recordings of the 35 presentations and the abstracts for the 9 posters AOML and HRD researchers presented (or were co-authors) at the Conference are available online from the AMS website:
