A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
If the named tropical system intensifies further and reaches winds speeds of 48 knots (89 km/h; 55 mph), then it will be classified as a severe tropical storm. A severe tropical storm is designated as a tropical cyclone when it reaches wind speeds of 64 knots (119 km/h; 74 mph). If a tropical cyclone intensify further and reaches wind speeds of ...
The typhoon has also surpassed the strength of any storm recorded in 2022 and now stands equivalent to a category 5 super typhoon. #Mawar now up to 150 knots (175 mph) per latest JTWC advisory.
Should the storm intensify further and reach sustained wind speeds of 48 knots (55 mph; 89 km/h) then it will be classified as a severe tropical storm. [19] Once the system's maximum sustained winds reach wind speeds of 64 knots (74 mph; 119 km/h), the JMA will designate the tropical cyclone as a typhoon—the highest category on its scale. [19]
