HRD Debrief for missions into EP95/Pre-Ivo in collaboration with OTREC – 3 March 2020

HRD researchers and our collaborators from the NSF-sponsored Organization of Tropical Eastern Pacific Convection (OTREC) experiment discussed the results from the 4 P-3 and 3 NCAR G-V HIAPER missions into EP95 which eventually became Hurricane Ivo in the Eastern Pacific. IFEX flew 4 P-3 missions from Liberia, Costa Rica into the disturbance that became Ivo, … Continue reading HRD Debrief for missions into EP95/Pre-Ivo in collaboration with OTREC – 3 March 2020

HRD Seminar – Dr. Altug Aksoy (CIMAS/HRD) – 3 March 2020

Dr. Aksoy presented a seminar titled “Assimilation of Coyote UAS Observations in Hurricane Maria (2017): Optimization of Data Impact”. ABSTRACT The Coyote is a low-altitude small unmanned aircraft system (sUAS) that is air-launched from the NOAA WP-3D (P-3) hurricane hunter aircraft through its existing standard A-size sonobuoy launch capability. Its meteorological sensors directly measure temperature, … Continue reading HRD Seminar – Dr. Altug Aksoy (CIMAS/HRD) – 3 March 2020

Paper on how tropical cyclones can intensify in high shear released online in Monthly Weather Review

When the wind within about 150 miles of the center of a tropical cyclone (what we call the near environment) is very different at the bottom and the top of the storm (what we call wind shear), the storm usually weakens, especially if the storm is already weak. However, sometimes this doesn't happen, and the … Continue reading Paper on how tropical cyclones can intensify in high shear released online in Monthly Weather Review
