NOAA’s G-IV hurricane hunter jet is preparing for a Saharan Air Layer Experiment (SALEX) around Tropical Storm Erika. The proposed flight track is shown below. They will depart at 10:00AM local time from Barbados and fly an eight hour mission. The goal of this flight is to collect data around the Tropical Storm Erika and sample the dry air around it. The data collected from this flight will improve our understanding of how the dry air interacts with the storm. The dots on the flight track (shown in green) represent the aircraft turn points. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.
