Summary The goal of this proposed project is to examine the hypothesis that changes in tropical cyclone intensity and structure depend on: i) vertical alignment of the initial vortex ii) characteristics of the upper-level environment, iii) tropical cyclone structure, iv) phasing of the tropical cyclone and the environmental features, and iv) feedback of the tropical cyclone onto the environment. A factor common to all of the above features is the outflow from the tropical cyclone into the large-scale environment. Observations of the interactions between a tropical cyclone and the complex upper-level environment of the subtropical Atlantic and the subtropical western North Pacific will be used to examine the spatial and temporal changes in TC outflow that influence TC intensification versus decay. Additionally, the sensitivity of numerical model forecasts to initial conditions that include observations of the tropical cyclone outflow will be investigated.
