The present study aims at using this new data in conjunction with data from previous field experiments, such as NAMMA, GATE, and TOGA COARE, to evaluate three existing theories: top-down vortex merger (Ritchie and Holland, 1997; Simpson et al., 1997), top-down shower-head (Emanuel, 1993; Bister and Emanuel, 1997), and bottom-up vortex merger (Montgomery and Enagonio, 1998; Enagonio and Montgomery, 2001). Additionally, these observations are used to briefly examine the newer marsupial framework for tropical cyclogenesis in African easterly waves (Dunkerton et al. 2009). The processes associated with each of these theories create unique signatures in wind, vorticity, potential temperature, and humidity fields. Timelines of these fields, created from composited mean dropsonde soundings, are used to determine the system-wide evolution. Further, the temporal evolution of sub-system processes, which are minimized or removed as a result of the compositing process, are identified in isobaric surface plot series. While previous studies have shown that no theory completely explains tropical cyclogenesis, it is hoped that a thorough analysis of these data sets will highlight both consistencies and inconsistencies between theory and observation.
