“…The cyclone Shaheen was formed due to the remnants left behind by the previous cyclone Gulab [10]. The latter initiated its track from the Bay of Bengal on 24 September 2021 and during its landfall it crossed almost the entire Indian peninsula from east to west (Figure 2) to set a favorable environment for Shaheen to grow northwest of India a few days later.…”

“…The formation of Shaheen in the Arabian Sea on 30 September 2021, marked a rare meteorological event [9]. This uniqueness was characterized by several distinctive attributes, including its remarkable persistence over the Indian mainland [10] and its emergence during an active southwest monsoon period in the month of September [11]. Furthermore, it was the first severe cyclonic storm to hit the northern coast of Oman in almost 150 years [9], a fact that underlines the exceptional nature of this event.…”

Tropical Cyclone Shaheen (TCS), originating in the Arabian Sea on 30 September 2021, followed an east-to-west trajectory and made landfall as a category-1 cyclone in northern Oman on 3 October 2021, causing severe floods and damages before dissipating in the United Arab Emirates. This study aims to analyze the synoptic and dynamical conditions influencing Shaheen’s genesis and evolution. Utilizing ERA5 reanalysis data, SEVIRI-EUMETSAT imagery, and Sorbonne University Atmospheric Forecasting System (SUAFS) outputs, it was found that Shaheen manifested as a warm-core cyclone with moderate vertical wind shear within the eyewall. Distinctive features included a trajectory aligned with rising sea surface temperatures and increased specific humidity levels at 700 hPa in the Arabian Sea. As Shaheen approached the Gulf of Oman, a significant increase in rainfall rates occurred, correlated with variations in sea surface temperatures and vertical wind shear. Comparative analysis between SUAFS and ERA5 data revealed a slight northward shift in the SUAFS track and landfall. Advance warnings highlighted heavy rainfall, rough seas, and strong winds. This study provides valuable insights into the meteorological factors contributing to Shaheen’s formation and impact.
