| Abstract | Rapid Intensification (RI) of tropical cyclones (TC) is one of the most challenging processes to predict even with the latest scientific understanding about TCs and technological developments in coupled modelling. The frequency of RI events in the Arabian Sea (AS) has doubled since 2013. Studies highlight that India experiences the highest number of landfalling RI cyclones among the North Indian Ocean (NIO) countries. In this review, we present a bibliometric analysis of RI literature published since 1982, using peer-reviewed studies from Scopus and scientometric visualization through VOSviewer, to understand the ongoing research trends, collaborations, and emerging themes in this field. The analysis reveals a global transition in research focus over the years from diagnosing environmental precursors such as vertical wind shear, ocean heat content, mid-level humidity, and inner-core structure using high-resolution numerical models, to the adaption of AI and ML approaches in recent years. Compared to other ocean basins, research on RI in the NIO is still in its infancy as reflected by the relatively lower number of publications identified in this bibliometric study. Additionally, recent research highlights a shift from classical RI theory toward recognizing long-lived, sustained intensification and explosive, short-lived intensification occurring even under strong shear, with climate change increasingly linked to this shift, although the exact processes remain poorly understood. Studies in the BoB have received relatively more attention, likely due to its higher cyclone frequency and socio-economic vulnerability in that basin, whereas the AS remains less studied, reflecting both fewer cyclone occurrences and limited observational data. Despite the reported progress, key gaps remain, including understanding of inner-core dynamics under multi-scale forcing, basin-specific differences that weaken model transferability and incomplete representation of air⿿sea interactions and mesoscale features. The study aims to guide future research priorities, methodological advancements, and interdisciplinary collaboration in the field of TC RI. |
