The energy for tropical cyclones is primarily delivered to the atmosphere by the water vapor evaporated from warm ocean surfaces. this energy is released within the atmosphere through condensation in thunderstorms and distributed by the persistent, organized wind circulation of the storm. from the color coding of storm intensities indicated on the figure 1 map of hurricane nate (#14), and hurricane irma (#9) upon making landfall, the weakening of the storms’ energy would likely have been due to a. reduced evaporation when over landb. increased surface roughness slowing windsc. both of these factors
