Cyclone “Biparjoy” intensifies in the Arabian Sea, posing significant risks and uncertainties for the affected regions.
- The India Meteorological Department (IMD) reports the storm’s rapid development, expecting it to strengthen into a severe cyclonic storm with winds reaching 115-125 kmph and gusts of 140 kmph on June 8, 2023.
About Cyclone “Biparjoy”:
A cyclone is a low-pressure system that forms over warm waters. Usually, a high temperature anywhere means the existence of low-pressure air, and a low temperature means high-pressure wind.
How it was named?
- ‘Biparjoy’ by Bangladesh and the word means ‘disaster’ or ‘calamity’ in Bengali.
How are cyclones named?
- Countries follow certain existing guidelines to name cyclones on a rotational basis.
- Worldwide, there are six regional specialised meteorological centres (RSMCs) and five regional Tropical Cyclone Warning Centres (TCWCs) mandated for issuing advisories and naming of tropical cyclones.
- IMD is one of the six RSMCs to provide tropical cyclone and storm surge advisories to 13 member countries under the WMO/Economic and Social Commission for Asia-Pacific (ESCAP) Panel including Bangladesh, India, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates and Yemen.
Cyclones in the Arabian Sea: A quick recap
- Frequency of Cyclones: It is not rare for cyclones to develop in the Arabian Sea. While less frequent than in the Bay of Bengal, cyclones in this region are not uncommon.
- Favorable Months: June is one of the favorable months for the formation of cyclones in the Arabian Sea.
- Factors Influencing Cyclone Formation: Cyclones form due to low-pressure systems over warm waters. The Bay of Bengal is slightly warmer, but the Arabian Sea is also getting warmer due to climate change, leading to an increase in cyclones.
- Coriolis Effect and Weather Systems: In a depression or low-pressure situation, the air blows in an anticlockwise direction in the northern hemisphere, influenced by the Coriolis Effect.
