Cyclone formation in Arabian Sea

  • Cyclones formed in the Bay of Bengal side of the north Indian Ocean are more frequent and stonger than those on the Arabian Sea side.
  • Meteorologists suggest the relatively cold waters of the Arabian Sea discourage the kind of very strong cyclones that are formed on the Bay of Bengal side; Odisha and Andhra Pradesh face the brunt of these cyclones every year.
  • Five cyclones originated in the area in 2019 — Vayu, Hikka, Kyarr, Maha and Pavan
