Abstract
This study investigates historical variability of Atlantic Basin tropical cyclones (TCs) using a novel framework that groups TCs by the first letter of their assigned names. TC characteristics were analyzed through non parametric trend tests to assess temporal patterns for different TC variables. Correlation testing was used to identify TCs relationship to large-scale climate modes. Results indicate that early-letter TCs have been forming earlier in the year and achieving weaker peak intensities compared to historical counterparts. In contrast, later-letter TCs have become proportionally stronger over time, masking these intraseasonal shifts in aggregate analyses. Correlation testing revealed strong modulation of TC activity by ENSO, the Atlantic Meridional Mode, The North Atlantic Oscillation, and the Atlantic Multidecadal Oscillation, while geospatial patterns such as landfall and genesis location showed no meaningful long-term trends. These findings highlight the importance of non-aggregate TC research designs and the dominant role that climate modes play in the modulation of Atlantic Basin TCs.
