A Diagnostic Phase Space for the Structural State of Pre-genesis Tropical Convective Systems
The phase space is constructed so as to identify the current state of the structure and immediate environment of pre-genesis tropical convective systems. The immediate research application of this tool is to produce homogeneous subsets of cases for compositing. This approach to compositing retains the positive characteristics of both case studies and composite studies (the detailed analysis and representativeness, respectively) while minimizing the drawbacks of each (the lack of representativeness and loss of highly variable details, respectively). Additionally, insight on the variability of the system structural evolution can be gained by examining the variations in the trajectories through the phase space. Applying the pre-genesis phase space in real-time using operational models will provide a visualization of the current and forecasted state of a tropical convective system. Furthermore, application to model ensemble output presents the opportunity to examine the uncertainty in the forecasted structure and could potentially pave the way for future predictability studies regarding the structure of these systems.
