40 m/s). An anomalously high mid-tropospheric relative humidity (RH) (~90%) is indicated at the developing stage, indicating the onset of RI, during which the system showed RH ~100% at the mid-troposphere. On 14 June, when the system reached VSCS, the simulated storm's low-level relative vorticity was ~359.93 × 10 –5 s-1, whereas ERA-5's was ~175.39 × 10 –5 s-1only.The simulated storm cyclone energy (9.35×104 knts2) was lower than the observed (11.54 ×104 knts2). The significance of the results obtained from the study is that the model can skillfully simulate the track and intensity of an Arabian Sea TC and capture TC Vayu's cyclogenesis. The study also provides insight into the cyclone's synoptic parameters, such as mid-tropospheric relative humidity, low-level relative vorticity, and cyclone energy, during its development and intensification. The study's findings can be useful in improving the accuracy of tropical cyclone forecasting and enhancing our understanding of the physical processes involved in their formation and intensification for the Arabian Sea region.
