Expected Results:
  • Increase understanding of the energy transfer from the ocean to the atmosphere in the hurricane environment.
  • Development of hurricane balloon will be a major technological advance for collection of data in hurricanes.
  • Project will increase the accuracy of surface energy flux estimates used in hurricane numerical models. These models are one of the primary resources for hurricane forecasting
