Hurricane Katrina from Space

Technology and Modeling Innovations Usher in the 2016 Hurricane Season

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) are at the vanguard of hurricane research. Each hurricane season we fly into storms, pore over observations and models, and consider new technological developments to enhance NOAA’s observing capacity and improve track and intensity forecasts. The 2016 hurricane season will provide an opportunity for our scientists to test some of the most advanced and innovative technologies and refined forecasting tools to help better predict a storm’s future activity.

Hurricane Danny & Tropical Storm Erika Provide Wealth of Research Opportunities for the 2015 Hurricane Field Program

AOML’s hurricane researchers conducted a number of field activities in August that provided data and critical insights into two Atlantic tropical cyclones, Danny and Erika. The two storms enabled researchers to test new instruments in support of the 2015 Hurricane Field Program and conduct research that will benefit future forecasts. Among the highlights were more than 15 successful manned and unmanned aircraft missions into Danny and Erika to collect and provide real-time data to the National Hurricane Center (NHC), as well as evaluate forecast models.

Upcoming Observations with Underwater Gliders

Underwater glider SG610, deployed on July 14, is located in the Caribbean Sea. This glider navigated in a SW, then in a SE, and now in a SW direction since it was deployed. The temperature and salinity profile observations indicate that on July 25 this glider started sampling waters of a cyclonic eddy that is now centered at approximately 16.5°N, 67.5°W, and has a radius of ~0.75deg as derived from satellite altimetry observations. These profile observations show a decrease in the salinity maximum, and a shallowing of the depth of this maximum salinity and of the depth of the 26°C isotherm.

Gliders Patrol Ocean Waters with a Goal of Improved Prediction of Hurricane Intensity

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory are in the Caribbean to launch two underwater gliders from a vessel off Puerto Rico to collect temperature and other weather data to improve hurricane forecasting.One of the gliders will collect observations in the Caribbean Sea, and another in the North Atlantic Ocean. They are positioned to operate over the next six months (June-November) collecting data in areas where hurricanes are common and areas where there is a lack of environmental data.
