So far two intense cyclones has formed, named "Tauktae" and "Yaas", over Northern Indian Ocean .
Tropical cyclone observation has been carried out over the past couple of centuries in various ways. The passage of typhoons, hurricanes, as well as other tropical cyclones have been detected by word of mouth from sailors recently coming to port or by radio transmissions from ships at sea, from sediment deposits in near shore estuaries, to the wiping out of cities near the coastline. Since World War II, advances in technology have included using planes to survey the ocean basins, satellites to monitor the world's oceans from outer space using a variety of methods, radars to monitor their progress near the coastline, and recently the introduction of unmanned aerial vehicles to penetrate storms. Recent studies have concentrated on studying hurricane impacts lying within rocks or near shore lake sediments, which are branches of a new field known as paleotempestology.
About cyclone Tauktae and Yaas
 |
| Cyclone Tauktae |
Cyclone Tauktae (pronounced as Tau'Te) has got its name from Myanmar, which means "Gecko".
Tauktae was a powerful tropical cyclone in the Arabian Sea that became the strongest tropical cyclone to make landfall in the Indian state of Gujarat since the 1998 Gujarat cyclone and one of the strongest tropical cyclones to ever affect the west coast of India. The second depression, first cyclonic storm, first severe cyclonic storm, first very severe cyclonic storm, and first extremely severe cyclonic storm of the 2021 North Indian Ocean cyclone season, Tauktae originated from a tropical disturbance, which was first monitored by the India Meteorological Department on May 13. The disturbance drifted eastward and organized into a deep depression by May 14. The storm soon took a northward turn, continuing to gradually intensify, and the system strengthened into a cyclonic storm and was named Tauktae later that same day. Tauktae continued intensifying into May 15, reaching severe cyclonic storm status later that day. Tauktae began to parallel the coast of the Indian states of Kerala, Karnataka and Maharashtra, before rapidly intensifying into a very severe cyclonic storm, early on May 16. Early on May 17, Tauktae intensified into an extremely severe cyclonic storm, reaching its peak intensity soon afterward. Later that same day, Tauktae underwent an eyewall replacement cycle and weakened, before restrengthening as it neared the coast of Gujarat, making landfall soon afterward. After making landfall, Tauktae gradually weakened as it turned northeastward, moving further inland. On May 19, Tauktae weakened into a well-marked low-pressure area.

| Cyclone Yaas |
The cyclone named 'Yaas' was the second storm of the year, which formed over the east-central Bay of Bengal given by Oman. The name is derived from the Persian language, which means Jasmin in English.

Yaas was a relatively strong tropical cyclone that made landfall in Odisha and also brought significant impacts to West Bengal during late May of 2021. The second cyclonic storm, second severe cyclonic storm, and second very severe cyclonic storm of the 2021 North Indian Ocean cyclone season, Yaas formed from a tropical disturbance that the Indian Meteorological Department first monitored on May 23. Conditions in the basin favored development as the system became a deep depression later that day, before intensifying into a cyclonic storm on the next day, receiving the name Yaas. The system further intensified as it turned to the northeast, becoming a severe cyclonic storm on May 24 despite moderate wind shear. Marginally favorable conditions further continued as Yaas accelerated northeastward, strengthening to a Category 1-equivalent tropical cyclone and to a very severe cyclonic storm on May 25. Yaas crossed the northern Odisha coast around 20 km south of Balasore at its peak intensity as a very severe cyclonic storm on May 26. Upon landfall, the JTWC and IMD issued their final advisories as Yaas further weakened inland while turning north-northwestwards.
Naming Cyclones:
Cyclones itself has location specific terminology;
· Hurricane- Caribbean Sea, the Gulf of Mexico, the North Atlantic Ocean and the eastern and central North Pacific Ocean
· Typhoon- western North Pacific
· Cyclone- Bay of Bengal and Arabian Sea
· Severe tropical cyclone- western South Pacific and southeast Indian Ocean
· Tropical cyclone- southwest Indian Ocean
Global bodies like--World Meteorological Organisation (WMO), United Nations Economic and Social Commission for Asia, and the Pacific give names to cyclones. Besides, regional specialised meteorological centres (RSMC), as well as tropical cyclone warning centres, also prepare the names of cyclones.
The WMO and UN ESCAP comprise India, Myanmar, Bangladesh, Sri Lanka, Thailand, Pakistan, and Oman. In 2018, the WMO and ESCAP included five more countries--Iran, Qatar, Saudi Arabia, United Arab Emirates, and Yemen.
Last year, there were list of 169 new cyclones, which were suggested by 13 countries.
Reason behind naming cyclones
The cyclones are named to identify the storms to send out warning notifications about their development. As the technical names could be difficult for the common people to remember and spread awareness on, naming them gives a unique identifier to these cyclones and makes it easier for the media and various authorities to disseminate information on them. If the speed of a cyclone is more than 34 nautical miles per hour then a panel gives it a special name.
Next cyclones
The list of 13 names prepared by each of the 13 nations are out in public domain. The next cyclone will be called 'Gulab', a name was given by Pakistan that will make landfall in the region. Other cyclones that are likely to hit the region in the coming months include Shaheen (the name given by Qatar), Jawad (the name given by Saudi Arabia), Asani (a name suggested by Sri Lanka), Sitrang (a name suggested by Thailand), Mandous (a name suggested by UAE), and Mocha (a name suggested by Yemen).
At present the first list is in use. Once the names in the first list are exhausted, the second list of the names in the table will be used, and so on.
And again, so far Nepal is not included in the countries name to provide cyclone name.
If you had to recommend the name of a cyclone from Nepal, what name would be right?
