Rare direct observations of coupled air-sea interactions during the intensification of a tropical cyclone over Gulf of Mexico’s warm oceanic mesoscale eddy features. New evidence supporting the hypothesis that enhanced buoyant forcing from the ocean is an important intensification mechanism in tropical cyclones over warm oceanic mesoscale eddy features. First direct observations of a positive oceanic feedback mechanism on storm intensity via wind-driven horizontal convergence of warm sea surface temperatures over warm oceanic mesoscale eddy features. New direct measurements of contrasting vertical shear, gradient Richardson number, and vertical mixing in Gulf of Mexico’s mesoscale eddy features during the forced stage in a hurricane. Direct measurements of the water mass response to a Gulf of Mexico hurricane, including an upper-ocean fresh water anomaly and the formation of a new density class.
