Sim Aberson highlighted in NOAA Research’s Profiles in Diversity

On June 2, 2000, President Bill Clinton declared June “Gay and Lesbian Pride Month.” The month was chosen to remember the 1969 Stonewall riots in Manhattan, NY. Patrons of a gay bar, Stonewall Inn, fought back against a police raid, sparking three days of riots. It is considered to be the start of the gay liberation … Continue reading Sim Aberson highlighted in NOAA Research’s Profiles in Diversity

Paper on the potential impact of radio-occultation data on tropical cyclone forecasts released online in Monthly Weather Review

Summary: Radio Occultation (RO) is a technique used to gather information on atmospheric temperature and moisture by seeing how signals from satellites change as they travel through the atmosphere. This study looks at how RO data from a proposed satellite system might improve weather model forecasts of where hurricanes will go (called track forecasts) and … Continue reading Paper on the potential impact of radio-occultation data on tropical cyclone forecasts released online in Monthly Weather Review

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

Lifesaving NOAA Support Following the Sinking of the Bourbon Rhode

The National Oceanic and Atmospheric Administration (NOAA) provided critical assistance during the international search and rescue (SAR) and recovery efforts that followed the sinking of the M/V Bourbon Rhode in Hurricane Lorenzo last fall.  This intra-agency NOAA effort included Hurricane Hunters from the Aircraft Operations Center (AOC), scientists from the National Environmental Satellite, Data, and … Continue reading Lifesaving NOAA Support Following the Sinking of the Bourbon Rhode
