Understanding Cyclone Names: Nisarga, Gati, Nivar, Tauktae, Yaas
The question asks us to identify what Nisarga, Gati, Nivar, Tauktae, and Yaas are names of from the given options.
Analyzing the Options
- New fighter aircrafts: Names of fighter aircrafts are typically technical designations or specific model names (e.g., Rafale, Tejas, F-16). These names do not sound like typical aircraft designations.
- Tourist places: Tourist places are geographical locations (e.g., Goa, Paris, Shimla). These names do not correspond to known tourist destinations.
- Weather stations: Weather stations are facilities that collect meteorological data and are usually named after their location or a technical code. These names do not fit the pattern for weather station identification.
- Cyclones: Tropical cyclones are often given names to help in tracking, communication, and awareness. The names Nisarga, Gati, Nivar, Tauktae, and Yaas are indeed names assigned to tropical cyclones that have occurred in the North Indian Ocean region in recent years.
Detailed Explanation of Cyclone Naming
The naming of tropical cyclones in the North Indian Ocean is managed by the India Meteorological Department (IMD) as a member of the World Meteorological Organization (WMO)/United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) Panel on Tropical Cyclones. This panel includes 13 member countries (Bangladesh, India, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, UAE, and Yemen) who contribute names to a list. When a tropical cyclone forms and reaches a certain intensity, a name is picked sequentially from this list.
The names provided in the question correspond to significant tropical cyclones:
- Nisarga: A very severe cyclonic storm that hit Maharashtra in June 2020.
- Gati: An extremely severe cyclonic storm that hit Somalia in November 2020.
- Nivar: A very severe cyclonic storm that hit Tamil Nadu and Puducherry in November 2020.
- Tauktae: A very severe cyclonic storm that hit Gujarat in May 2021.
- Yaas: A very severe cyclonic storm that hit Odisha and West Bengal in May 2021.
These examples confirm that Nisarga, Gati, Nivar, Tauktae, and Yaas are names of cyclones.
| Cyclone Name | Year of Occurrence | Region Affected |
|---|---|---|
| Nisarga | 2020 | Maharashtra (India) |
| Gati | 2020 | Somalia |
| Nivar | 2020 | Tamil Nadu, Puducherry (India) |
| Tauktae | 2021 | Gujarat (India) |
| Yaas | 2021 | Odisha, West Bengal (India) |
Therefore, based on the analysis and the nature of these names corresponding to tropical cyclones in the North Indian Ocean region, the correct identification is that they are names of cyclones.

Additional Information: Tropical Cyclones and their Impact
Tropical cyclones are intense circular storms that originate over warm tropical oceans. They are characterized by low atmospheric pressure, strong winds, and heavy rainfall. They rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Cyclones can cause significant damage through high winds, storm surges (a rise in sea level), and flooding.
The naming system helps in avoiding confusion when multiple cyclones are active simultaneously in a region. Each name is used only once in a particular basin, and names of very destructive cyclones are retired.
