| Abstract | Hurricanes are increasingly becoming more powerful and frequent as Earth continues to warm rapidly. Scientists are challenged with understanding and predicting complex storms to mitigate impending disasters. Remote-sensing instruments have been developed to aid in deciphering storm microphysics and kinematics, yet many limitations have hindered the comprehensive analyses of tropical cyclones. The Airborne Phased Array Radar (APAR) represents a groundbreaking advancement in hurricane research and forecasting. APAR– a next-generation airborne radar – will provide agile scanning capabilities, allowing a deeper understanding of the intricacies of atmospheric phenomena. APAR boasts dual Doppler and dual polarimetric (transmits and receives both horizontally and vertically polarized electromagnetic waves) capabilities, ideal for distinguishing between raindrops, ice, and snowflakes. To support APAR’s development, the APAR Observing Simulator (AOS) was created to simulate realistic APAR observations of high-impact weather events. By leveraging the advantages of APAR, the advanced structure of tropical cyclones can now be analyzed. This project investigates and compares the structure of tropical cyclones as theoretically sampled by APAR to the Tropical Rainfall Measurement Mission Precipitation Radar (TRMM-PR) as documented in the literature and observations made by the NOAA Tail Doppler Radar. With the construction of reflectivity distribution diagrams and a detailed literature review, comparative radar reflectivity characteristics are discussed. New structural information obtained from Particle IdentificationPlots and dual pol variables highlight the advantages of APAR. The enhanced capabilities of APAR reveal significantly greater detail compared to earlier observations. This highlights distinct reflectivity values and hydrometeors unique to various segments of tropical cyclones. This study proves that APAR has the potential to significantly improve the understanding of tropical cyclone structure and contribute to more accurate forecasting and research in the field of meteorology. |
