Utilizing datasets from the National Oceanic and Atmospheric Administration (NOAA) hurricane research aircraft over the last two decades, we identified and documented the thermodynamic and kinematic conditions in the vicinity of convective cells within the rainband regions of Atlantic hurricanes. Both lower fuselage and composited tail radar data are used to identify convective cells, primarily focused on those distinct from the rainband. Near-cell proximity dropwindsondes are selected, categorized and analyzed. Each dropwindsonde is categorized as either an inflow sonde, an outflow sonde, or a general environmental sonde based on its location to the cell and the sonde's thermodynamic and kinematic characteristics. After compiling these categories of sondes, thermodynamic variables and kinematic parameters are calculated and statistics are compiled.
The final goal of this research is to gain a better understanding of environmental characteristics associated with the initiation, morphology, and dynamics of convective cells in tropical cyclones. This study should lead to a better understanding of the physical processes responsible for these cells' evolution and maintenance, especially compared to those environments meteorologists are familiar with in other non-tropical cyclone severe weather convective situations.
