🔆 Cyclone Shakti: Severe Cyclonic Storm over Arabian Sea (2025)

📍 Classification:
✅ Cyclone Shakti was classified as a Severe Cyclonic Storm (SCS) by the India Meteorological Department (IMD) with wind speeds of 130–145 km/h.
✅ It formed over the east-central Arabian Sea, serving as a key case for studying tropical cyclone dynamics — oceanic heat, Coriolis force, and atmospheric instability.

📍 Naming:
✅ The name “Shakti”, meaning power and resilience, was proposed by Sri Lanka under the WMO–ESCAP Panel on Tropical Cyclones.
✅ Cyclone names are drawn from lists submitted by 13 member countries (including India, Bangladesh, Oman, Myanmar, etc.) to enhance clarity in communication and disaster management.

📍 Formation Mechanism:
✅ Warm sea surface temperatures (>27°C) provided latent heat for convection.
✅ Low pressure formed at the surface; Coriolis effect induced rotation.
✅ Upper-level outflow maintained structure, while low wind shear over the Arabian Sea (Oct 2025) aided intensification into a Severe Cyclonic Storm.

📍 Climatic Background:
✅ Arabian Sea cyclones are rising in frequency and intensity due to warming trends — India’s mean temperature has risen by ~1.2°C since 1901 (CSE, 2017).
✅ Reduced vertical wind shear and higher moisture transport from the equatorial zone support cyclone formation along India’s west coast.

📍 Geographical Path:
✅ Formed near 21°N, 66.8°E, around 270 km southwest of Naliya, 300 km east of Porbandar, and 360 km south of Karachi (as of Oct 3, 2025).
✅ Moved northwestward under subtropical westerly influence, a typical post-monsoon trajectory.
✅ The Arabian Sea’s semi-enclosed basin traps heat and moisture, making it increasingly cyclone-prone.
