The ENSO is a recurring climatic pattern involving temperature changes in the waters of the eastern and central tropical Pacific Ocean, and changes in the patterns of upper and lower-level winds, sea level pressure, and tropical rainfall across the Pacific Basin. It was coined by Henry Peddington because the tropical storms in the Bay of Bengal and the Arabian Sea appear like coiled serpents of the sea. These classifications offer the opportunity to improve the way extratropical cyclone evaluation in climate models is currently done by giving more insight into the dynamical and physical processes that occur in climate models (rather than just evaluating the mean state over a broad region as is often done). Which of the following statement(s) is/are INCORRECT. The lowest official classification used in the North Indian Ocean is a Depression, which has 3-minute sustained wind speeds of between 20–31 mph (31–49 km/h).

For e.g. Hurricanes are found in the Atlantic and Northeast Pacific, typhoons are found in the Northwest Pacific. Majorly formed from clouds and thunderstorms, a Tropical cyclone is a rotating system majorly originating from the subtropical or tropical regions. The IMD follows a five-stage classification for cyclones, with the lowest a ‘cyclonic storm’ generating wind speeds of 62-87 kmph, and the highest a ‘super cyclonic storm’, generating winds over 222 kmph. Cyclone Vayu is likely to halt the northward progression of the monsoon for a few days. Tropical cyclone, also called typhoon or hurricane, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain.Drawing energy from the sea surface and maintaining its strength as long as it remains over warm water, a tropical cyclone generates winds that exceed 119 km (74 miles) per hour. Cyclones are classified into five different categories on the basis of wind speed, from Category 1 to Category 5. Vayu, even at its most powerful, therefore would only be categorised as a “severe cyclonic storm”, while Fani was an “extremely severe cyclonic storm” and almost satisfied the conditions for classification as a “super cyclone”.
