Paper on how the regions closest to the surface changed during the landfall of Hurricane Irene in 2011 released online in The Journal of the Atmospheric Sciences

Summary: Objects on land and the land itself cause wind to be weaker at the surface than above due to friction.  In hurricanes, the strongest wind occurs where friction is no longer important, near the top of a region we call the boundary layer.  Some people live close to the surface, but others live in … Continue reading Paper on how the regions closest to the surface changed during the landfall of Hurricane Irene in 2011 released online in The Journal of the Atmospheric Sciences

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
